Interlux Brightside

I chose the Primekote 404/414 as primer because, at the time, I had not decided between Brightside and Perfection.  I have long referred to Perfection as 'the poor man's Awlgrip' and to Brightside as 'the poor man's Perfection'.  All three share similar qualities: they are rugged, hold up well to UV and to seawater, go on very well with a minimum of application effort (just roll on and take care) and are somewhat compatible in that primer for any one of them can be used with the lower grades of paint.  If you can't afford Awlgrip or a guy like Jeremiah at CY to apply it for you, your next bet is to apply the two-part epoxy Primekote and then pick either Perfection or Brightside.

Jerry, from the C44 Second Alarm, has been my boatyard neighbor for two seasons now.  He very generously offered to assist me with the application and did most of the rolling of both the Primekote and the Brightside himself.  I defer to his expertise in applying surface finishes as he's completely redone the hull of his 1981 boat from bare fiberglass to finish gelcoat, almost entirely on his own.  We readily share concerns, advice and encouragement and so he was a natural and welcome partner in this vital chore for Diana.


Taking the time to do it now


I took the better part of two days off from work for this.  To some this sounds irresponsible; but, to me, a boat is like a pet.  If it needs you now, it needs you now; and you are irresponsible to put it off till a situation becomes unhealthy.  I don't consider boats mere things, like that.  They have spirits and souls and feelings and needs.  Sail one and you know what I'm talking about.  I saw it during the Sandy storm-- with 68,000 boats in New Jersey having insurance claims filed, you just know that some of them were owned by people who said, 'It's only a boat.  It's insured.'  I could use the money anyway.'

Forgive the harsh opinion; but these people clog up the insurance-claim process and annoy and delay those of us who truly care.  I saw BOATUS and many others come through like knights in shining armor for boat owners who truly cared-- and I worked very hard on restoring several of those boats myself, if only because of two things:

1. I know what you feel like when your boat needs work, since I love my boat as much as you love yours.
2. I want to see your boat happy and sailing again as much as I want to see mine happy and sailing again.  This is what I do, and this is why I do it.

So I was grateful to Jerry for his help but I knew he knows how I feel about it because I know he feels the same way about his boat.


Brightside lessons


Since this is me, I have to delve into the bad news first!

I uploaded these two pics in a large format to illustrate how the first coat of Brightside goes on.  Formerly both of these places on Diana were repaired, using a combination of Evercoat 27 and WEST epoxy with filler.  The first one, below, had some significant pitting in the gelcoat and, being on the shaded, close-quartered side of the boat when it was in The Swamp, I did not get the chance to finish fairing these.  In truth I didn't really see them that well there.  So Jerry and I decided, what the heck? --and we painted over them to see what we'd get.  I don't think you can notice in this picture but the Brightside does not cover imperfections very well, if at all.

So, Lesson #1 with using Brightside:
It is not latex house paint.  It is not 'high hiding'.  It changes the color and seals the surface; it does not fill divots at all.


The second pic, below, illustrates what I call 'the thin white panties problem'.  (You get no further explanation of the name.)  This was where I filled the factory-installed galley-sink drain hole (relocating it, with seacock, to the bilge).  I was anxious to see how well Brightside would cover over darker-colored stuff like the WEST epoxy with gray and tan filler in it.  The result was that one coat did pretty well.  This would disappear completely on the second coat.

So, Lesson #2 with using Brightside:
It does change color; but when it's white over dark, it'll take two coats.  This is in line with pretty much any other paint; but here I believe it is a factor of the thin application layer of Brightside.  You don't put it on thick; you do multiple coats.  (In other words, it's not Bilgekote!)


At the end of the day, the guys from the shop were coming out and saying things like 'Hey!  John has a shiny boat now!'  I doubt they realized what this meant to me-- it may be the first time I have received any kudos from others on my work with this boat at all.  Naturally I replied that it was all down to Jerry-- for his constant encouragement, invaluable assistance and almost-paternal admonishing me to keep moving.  This is a guy who supervises urban firemen-- he knows how to motivate people and in my case has done it well.


We got the second coat done the following day, after I spent the whole morning (18-20 hours' drying time) sanding this coat with 320.  We had one egregious error (mine, I am sure) where we had to retouch a place where I missed tipping (probably due to intense sun glare that side).  The attempt to get it on and all smooth was not successful.  It ended up being covered but as a lump that looks like a bulkhead pressing through.

So, Lesson #3 with Brightside:
You have about five minutes, and no more, to finish rolling and tipping applied paint.  Don't hesitate-- get it right now, and keep moving on.  You won't be able to go back and fix it; it'll mean another whole coat if you let it go.

This is all well anyway, as I'd like to redo a few places on the transom and resolve the matter of a few divots.  I'll do the third coat in the spring (as well as another barrier coat on the bottom).  For now, Diana's going under a shrink-wrapped cover so I can focus on the engine, the electrical system, and a few odds and ends that can be fit to the boat and finished in the shop.

Thanks again to Jerry for all his work; for this is really all down to him here.

Moving day

24 October 2014


I have not been happy with the boat's being where it's been.  This is sort of the 'swamp' of the yard.  Well-- it is not really a swamp-- Diana has been sitting on good solid packed gravel-- but the ground immediately beside her is low and tends to fill up in any rain.  This, in addition to the constant mosquitoes, makes doing boat work after 4.00 pm and on weekends less than fun.  So I contracted the guys to relocate Diana to a drier, happier place, especially with regards to facing another (her last?) winter on land.

Here in the Northeast, when placing a boat for the winter season, it is best to situate her nose-into the weather.  This is better for the boat, for any covers, for the stowage of gear on deck and on the ground, for persons entering the boat in the off-season, and for a host of a million other reasons.  Diana, especially, with her low-profile deck and cabin, heads to weather very well-- but all my covers and the cockpit have taken a beating over these (too many) years sitting stern-to the weather, which here in Delran comes to us on a direct line from Philadelphia (bearing from W/SW) in summer and from W and NW in winter.  The compass in the bulkhead shows her facing E/SE.  Enough said.


This is Diana's old spot, in 'The Swamp'.  Here Jerry's C44 Second Alarm has been moved to his new spot and I was standing, for the first time in two years, where his boat had been.  Together these boats and the others in this photo weathered Superstorm Sandy and all the rest.



Now I know how these guys work.  The guys from Riverside Marina come over, back the hydraulic boat carrier to the front of your boat, and then-- wait for it-- remove all the stands.  I mean all of them but the very back and the very bow.  I've seen them do this even on windy days, with the rig up.  Yikes.

Watching them do this with a C44 or Ben's Rhodes Reliant (with that narrow transom!) is unnerving.  Watching them do it with my own boat is an automatic case of the heebie-jeebies.  I was so paranoid that I subtly replaced the stands in the very back with a pair a little closer forward, though they were not at any bulkhead, just to persuade them to leave those as the last two.  But they moved them back (to right where they were before), saying they couldn't get the truck under it.  I was near fits.


Then, to really bring on the stomach acid, the forward pads on the truck would not find the boat.  I've seen this thing in action many times but always thought that for smaller boats the pads would angle inwards.  Apparently, they don't.  The picture shows the back ones too far forward and too low, the front ones way too high, and the keel (read that: whole weight of the boat) on a 3-inch-wide strap spanned between the wheels of the truck thing.  Sheesh.

Meanwhile, between snapping photos (which I did not really do so much) I was worrying that the pads in front are pushing against the v-berth shelf, probably popping off the rode-locker bulkheads I 'glassed there, and definitely scraping off the newly-applied primer paint.

Then Jeremiah in the shop says, 'It better not be scraping off the paint.  It's epoxy.  If they're scraping it off, it wasn't applied right.'  And it was applied right.

End result: Diana arrives across the yard safe and sound.  There was a problem with blocking her, as the guys could not get the strap out from under the keel without blocking the keel bottom in the same place as before-- meaning I still can't scrape, prime and barrier-coat the very bottom.  But I can sort that out another day.  The bulkheads forward were fine (of course).  And the epoxy primer survived very well-- the traces of black wiped off with one hand while I was talking on the phone.  No worries.


In this location the barn part of the shop will block most wet snow.  The weather now comes from off Diana's nose or from slightly to port.  I will have this shrink-wrapped by the end of November (after topcoat on the hull).

The few odd places where the barrier coating was sanded through are the repairs I had to make for the cracks; this is reported elsewhere.  Jerry gave me some leftover stuff so I may not need to go into the quart kit of Pettit Protect that I bought for these (and for the rudder).  The gray cover is because of the instrument holes in the back of the cabin and because the forward edge of the hatch hood is still open (needing woodwork, the last major job to be done to the deck).

On the deck there is a bucket upside-down over the mast step.  The step will be removed for the deck to be painted and then reinstalled with 5200.

The holes forward, where the running lights were mounted, are to be covered with Plexiglas panels, as Diana's eyes (more on this 'secret' later). 

The foredeck hatch is slid open in this picture.  I have to put hinges on it, then remove them, then varnish the whole thing, which, with the boat under shrink-wrap, can easily be done in the shop.


Little Diana likes her new spot in the sun!


In the background can be seen the CY spars rack, welded and bolted to the side of the former storage trailer that is now the lumber-storage room for the shop.  On this rack are C44 spars, the ones for Dave's Reliant, and a few others.  Jeremiah puts each up there with the forklift (another operation that has to be seen to be believed).

I prefer six stands, not four (not counting the bow) because it's simple to pull one down to paint the bare spot.  The plywood steps came over from Diana's old place because I used them to fill and fair the old bow damage and will use them now to reinstall the section of toerail, the stem fitting and the anchor roller.  In this photo I have not yet moved the spars and the workbench to the new spot.

The half-gallon of iced tea is Turkey Hill from 7-11-- the very best cold green tea you can get!  :)

Finally! --it's paint.

9-10 October 2014


I have been procrastinating the hull paint on this boat for an inordinate time.  This is really 'just because' --I truly haven't felt like investing the time and effort into it till now.  But I've had the gallon kit of Interlux Primekote for a while, just for when I decided to do it, and so I finally bowed to the constant encouragement of my friend and boatyard neighbor Jerry (C44 Second Alarm) and together we attacked this.
(The spots on the bottom are my repair of some hull cracks that had spread through the Pettit Protect barrier coating that I applied last year.  Discovering these was distressing; but I've been determined to have this boat done properly and so the Dremel took was applied right through it and WEST epoxy, with milled fibers as filler, was troweled into the gouges.  As of now it's really pretty good.)


Jerry did the rolling and I was going to try tipping it, for which I bought a couple of really good brushes, but we found that Primekote doesn't want to be tipped.  We also found that it should be thinned more than the 20% the label advises-- I approximated about 25% (or a little more) into each batch.  We mixed 5 batches of about 20 ounces each and this did a little more than two full coats of the hull.  Jerry was a champion with the rolling and really made the paint spread well with virtually no heavy spots.


Earlier pics will show the extensive repair on the transom.  Upon removing the center-mounted backstay tang, I discovered its load had sort of impressed upon the transom, creating a hollow.  I filled this with new 'glass and plenty of WEST epoxy with Microlight.  With Jerry's help I sanded the entire hull with 80 grit, and then 120 grit, using DryGuide, this marvelous black powder that, applied to the hull before sanding, illustrates clearly where your highs and lows are.  Sand it all off and it's fair-- and, amazingly, that stuff does not lie.  This hull is incredibly fair-- and, in some places, fairer than it was fresh from the factory!


I haven't seen this transom all one color since I brought the boat up to Delran!


This poor boat had numerous close encounters with pilings and the like, to the point where some PO cut off a section of bow rail to effect a repair.  I took this off again to repair his repair and left it off for the painting.  By some odd coincidence this is the very section of rail that needs to be cut down to accommodate the anchor roller (as it's tradition for sailboats to have the primary anchor rode to starboard).  The whole nose has been redone with 'glass, Microlight, milled fibres, and endless sanding.  Now in the bright white Primekote it looks almost done.

The holes formerly occupied by the hull-mounted running lights will be fitted with teardrop-shaped black Plexiglas windows, giving light to the forepeak locker and finishing off the bow in a familiar way.  I'm putting little blue LED lights in here (called 'docking lights' on the breaker panel) to represent Diana's personality.

Waterline stripe

I've been getting frustrated that the progress I have been making on this boat does not look like progress; so I reached a limit recently and opened the can of Pettit Protect I've had for over a year and just went for it.  I cannot say this is a perfect job; there are minor spots in the hull I really should have faired better or filled better, and of course the first roller cover broke down after two coats and for the third I had to dig into my horde of stores for another which was too nappy and not as good.  But the paint's on the boat and that's good enough. 
   
I chose the Pettit Protect over Interlux Interprotect for one solid reason.  To reach the desired thickness, Interprotect requires five coats where as Pettit Protect requires only three.  It goes on thicker.  Therefore I accomplished this with only one roller replacement and in only about three hours of a hot Saturday in August.  
   
The rugged outline of the top edge of paint wants explanation.  In filling and fairing the hull's numerous cracks, I encountered quite a few of what I determined were 'bottom-style' cracks above the designed waterline, especially in the bow.  These are typical of any boat; and for a sailboat that one must conclude will be heeling more often than not, under way, the imposed delineation of a waterline is pretty arbitrary.  So I prepared these places as I would for any 'underwater' area; and once the waterline is established the gray can be sanded down above the line to accept topsides paint.   
  

The black Sharpie lines, applied at the upper edge of the green-tape stripe, will represent the lower edge of the painted stripe(s).  Thus I am 'cheating' the original waterline up about two inches.  

I lowered the rudder in its shaft tube but without digging a hole I was unable to remove it entirely.  As of this picture it has been sealed and re-'glassed (the yellowish stuff is epoxy, with some Microlight filler).  I found every seam in the rudder shell to have been open and filled with bottom paint (not a good sign), which was responsible for the whole thing being saturated in water.  As I used up all the Pettit Protect on the hull, I will have to buy more for the rudder and the stand squares.
   
From earlier photos one can see that I stripped the entire hull bare-- leaving no stripes.  Earlier I had plotted all three lines-- float waterline, designed waterline, and top of bootstripe-- and recorded the measurements.  These current lines come from those plots.
   

This sort-of-closeup view shows my 25-foot Stanley tape clamped along the toerail of the boat.  Using this as a kind of number line, I dangled the other Stanley tape from this, at prescribed intervals, taking 'soundings' down along the hull to the stripe.  To get the waterline back onto the hull, I had only to read my numbers back and to plot the marks from them.  
  
I am not sure I'm happy with the replotted marks.  Though I did the plotting accurately, I fear the boat is going to be too heavy, especially forward, and especially to starboard, which worries me.  To starboard are the engine-starting battery, the galley, the toilet itself, the toolbox, the primary anchor and (short) chain rode, and the microwave oven as well as the skipper's usual sitting area below, where the computer and stereo are located.  Everything else is more of less balanced out by a complement to the other side.  For now I shall let these lines alone and count on shifting some weight about (possibly by storing all canned goods to port, for example).   
   
In the background Jerry's 1980 C44 can be seen.  Jerry's a liveaboard who's been doing a heroic job stripping bad 'glass from his boat's bottom and re-'glassing the whole thing.  His stamina and indefatigable fortitude are an inspiration.
  
  
After taking some of these pics I just had to snap this view of Diana's underside all recently done in pewter gray undercoater (Pettit Protect).  
  
Yes; the keel looks a little bent out of shape.  Believe me-- it was much worse before I got my hands on it.
   
The paint does look a little blotchy in this view.  Maybe it's glare.  I can vouch for the effort than went into smoothing this; and the result really is pretty good.  Undoubtedly it's better than it was when new.  
  
The little oval block affixed to the bottom, aft of the keel, is the fairing block I made for the bronze drain plug.  Maybe it's just overkill; but, then again, every girl can use a little help....

Bare-bottomed girl

I suppose this really should read 'bare-bottomed lady', as she is 38 years old; but it got attention.


This status is the product of about 2 seasons of scraping and sanding (with everything else I have to do).  I began using Stryp-Eaze but I had a very bad scraper and made little progress.  I changed to Pettit's Bio-Blast, which I found did not respond to following the directions as they were given.  It's supposed to stay on 15-25 minutes without drying; but I found that on a moderately-warm day, not even hot, it went from gel to utter varnish in much less time than that.  The best tactic was to apply it, using a brush from a cup, wait about 5 minutes and then go at it.  I got a really good deal on a scraper-- with two sets of blades-- at Harbor Freight for $2.99.  No complaints at all with this-- it worked great; but I did rotate the 4-sided blade several times before sharpening it as it did jam up pretty quickly.

I also found that the chemical stripper, having to soak into the paint in order to work well, does not work overhead!  On surfaces that were more on the bottom than on the sides, apparently the stripper merely hung on the paint, softening the very outer layer but doing little else.  So all of the bottom (read that: hardest-to-work-with) places were done mechanically, with 'Dusty' the orbital sander, 50-grit discs and hard work.


Here is a pic from earlier in the season which shows the very bottom layer of paint.  There were, apparently, three layers, all of old-school hard-shell antifouling.  This one was, of course, hardest to remove.  The chemical stripper did not permeate this paint, no matter how many times it was reapplied-- the greenish places are dried Bio-Blast which did not cut it.  For the most part it came off with the orbital sander (which meant that, for the most part, I wore my work home).

(May-Be is my cousin Mike's Capri 26 which was sold in the middle of this summer and relocated to its new home in New York.  This freed up plenty of room to work on mine!)

The black stripe came off well; apparently it was just standard enamel and the stripper ate it easily.  It was always too small and I will be redoing it completely more in keeping with the lines of the boat.


I am sure to have more on this later; but here I will add a reminder that the boottop stripe always has sheer, in both top and bottom edges.  Nothing looks worse than a perfectly-straight boottop, like how this one was.  The top, of course, reflects the sheerline of the boat.  The bottom edge does too; but much less conspicuously. For a boat of this size the bow end might be 2-1/2" above the actual floating waterline, the middle about 1-1/2" and the stern about 2" (I'll post my actual dimensions when I have worked them out). The bottom paint is exposed to the stripe (there should be NO hull color showing, ever).  Without getting too metaphysical you might think of the revealed bottom paint as that thin line of not-yet tanned skin that the woman shows just beyond her swimsuit at the beach.  It looks like vulnerability (a boat at rest should never show her bottom paint to strangers!) but it also indicates strength and hardiness, that she can and will endure whatever these elements hand out.  No one admires a boat that looks like it can barely stay afloat!


This view shows (albeit only slightly) some of the patching I did to the bottom.  The old through-hulls were removed and filled (the two larger circles below and beyond the stand pad).  Below them are seen the new through-hulls, which my daughter helped me install (it's always a two-person job).  The forward one is for the old SR Mariner speedometer-- I got a new fitting from them and almost too late realised it had to be aligned fore-and-aft to ensure the paddlewheel works properly.  I had expected the alignment was done by the paddlewheel itself.

I have since faired the very top of the keel in front-- it looks awfully big here but it's not really.


The other blotches are places where the gelcoat was chipped, not from blistering but just from age.  I filled these using Microlight most of the time, just whenever I had some extra from fairing the deck or keel blade.  This is not the best stuff to use under the waterline; as the filling compound will soak up water; but this bottom will all be sealed in barrier-coat epoxy and so it'll survive just fine.

I also mean to carry the barrier coating up above the waterline in some places, merely to seal some cracks there; so as yet there is no paint-to line or masking involved.

It is important to note that these ancient-gelcoat cracks are not moisture blisters.  One task I had long feared to attempt was to get moisture readings on this hull; but Jerry was checking his C44 in the yard and I borrowed the meter for Diana.  Being so long out of the water it now reads a very respectable 6 and below (out of 22) just about everywhere.  The place along the port side of the keel, where I had detected some delamination and then repaired, now reads under 10.  This might even account for standing bilge water.  The starboard side, however, reads about 16 which is alarming.  I will probe this from inside when I get the chance (before barrier coat) but it may reflect bilge water as well.

(The rudder reads well over 22-- with loud pinging from the detector meter! --which I will address in another place.)




Poor Diana, of course, is understandably embarrassed to be laid so bare and undignified before strangers' eyes.  I told her she has nothing to worry about, that at least it's a very good-looking bottom; but she was very prompt, as soon as I had taken these photos, to rap me in the head with a bit of stray line and then to lash out at my leg as I vaulted out of the hatch--


By the way this still hurts (wearing long pants is like sanding it with 80 grit all day); and I have promised the boat to get the barrier coat on as soon as possible.  At least then she'll be in her pewter-gray underwear, not a bad look for any hull.
