Replacement cockpit drains - Take Two

18-19 July 2014


I don't think I mentioned this before, so....

The small brass fittings I installed about two seasons ago (here) were really too small.  After making a big deal out of putting them in, I decided to replace them with the very idea I have been advising other H25 owners to do for many years.

The original H25 drains were RC Marelon through-hulls straight out the back wall of the cockpit-- necessitating that water either climb up the 5/8" threshold to flow out or else stay in the cockpit pan.  I installed the little brass drains in the sole itself, fitted them with 90-degree elbows and though them good enough.  After consulting with my friend Roland (SV Moonshine) about his solo Atlantic crossing, I decided too big can never be big enough.

The fix I have been long suggesting for this entails the fitting of a rigid fiberglass tube straight out the very bottom corner of the cockpit pan through the transom.  In what has to be the most productive two two-hour work sessions I have ever had on this boat (even in the face of predicted rain), I drilled the holes, bedded these into place, removed the old ones and filled and faired the old holes.  I did one one day and one the next, after a full day of work each time.  It impressed even myself!


Here's the view from the cockpit.  The tubes are 1" inside, 1-1/4" outside diameter, pressed fiberglass, ordered from McMaster-Carr.  It was about $21 for one 60-inch piece, which, cut in half, fit perfectly for this application.  I deliberately made the cut on an angle, twisting each tube in its hole in order to fill the corner (shorter side inboard).  Bedded in 5200 and faired with WEST epoxy and Microlight, they look like they were molded there.


At the transom I allowed the excess length to just stick out and, when the epoxy had dried, cut them shorter with a hacksaw and used the orbital sander to smooth them over.  This picture doesn't show it so well, but the factory's installation wasn't symmetrical-- one old hole (filled as of this picture) will appear closer to the new tube than the other side.  I just eyeballed the site from above, applied a ruler and made them lead  out parallel to the centerline, straight aft from the corners of the cockpit pan.

The green tape covers the HIN.  I got some epoxy into it a while ago and decided to preclude any more messing it up.

The other two through-hulls are the Marelon ones I installed for the bilge pumps.


Looking under the cockpit the downward angle and parallel leads are seen clearly.  The duct tape is part of one of my 'mooyock' solutions for filling holes.  When the old through-hulls were taken out (with hammer and chisel), I taped over the holes in the inside and made up 'communion wafers' of fiberglass to stuff into the voids from the outside with epoxy.  Why try to fill a hole that's overhead or angled so that the epoxy will only dribble out?

This isn't a great view of it, but below the tubes is a little floor I installed aft of the low bulkhead in the foreground.  This low bulkhead, a little higher than the waterline, will contain water from any rudder-post leaks in the event of a rudder strike (which should be high on the list of any sailor's worst nightmares).  A small hole, here seen stained in epoxy, is fitted with a brass tube which will accommodate one of those little rubber transom-drain plugs.  It's not the most secure arrangement; but it's much better than having nothing at all in the event of this happening, for which Stephen Dashew says your best scenario is to crack the rudder blade.  Any other possibility involves catastrophic damage to the hull-- and, with your average production spade-rudder boat, probably the end of your voyage.


This pic, with the fuel tank in place, shows the upper end of the cockpit-drain tube.  With the little brass things in place, there had to be an elbow over the back edge of the tank that seriously complicated attaching fuel hoses and intruded on space for removing the tank.  Now this is practically structural-- no worries for stuff in the lazzarette weighting down the drain hoses till they fail or pop off.

(The dark spot on the tank is an old epoxy spill, not a leak or any damage.  This tank has been kicking about this boat for very long, getting dusty and spilled-upon, and only now (September) is is finally in its place for good.  Of course I've kept all the openings well taped-up!)

Head compartment

In these photos this is far from being done; but I was just fooling about with the camera and took some photos of the head area to record progress.


This is the head sink, which, as all H25 owners know, the boat did not originally come with.

The stainless-steel basin came from an old Chris-Craft; I bought it on eBay for $19.00.  Its drain goes through the forward bulkhead-- to get out of the foot area-- and then to a trap and down to the drain seacock.

The after portion of this countertop (to the left) lifts up for access to a 4-inch-deep compartment above the foot of the bunk.  The two openings outboard of the sink are for toiletries and towels.  The little mahogany stick on the forward bulkhead, inside the locker, is the cleat for the shelf in there.  The shelf divider is sitting against the hull.

I put the tissue dispenser in there to calculate the space for it; but I certainly won't rely on a cardboard tissue dispenser to be kept in the head, under the large foredeck hatch, aboard a 25-ft boat!

There is no headliner or hullliner in place in this photo.  The trim is not installed here either.

The wiring isn't really this messy-- it's just dangling down from the connections block above this doorway where the spar wiring enters the cabin and the cross-cabin circuits pass by.  When it is connected properly you won't see the danging bits in and out of the lockers.


This Wilcox-Crittenden Head-Mate toilet was given to me by a guy called Bill who was working on his friend's boat in Hancock's Harbor, NJ.  I saw it sitting outside the boat on a Sunday and left a note on it: 'If you are getting rid of this toilet, call me and I'll take it.'  The guy called me as soon as he returned to the boat.  It pumps perfectly well-- they must have been switching to either a larger bowl or just an electric one.  The intake/flush lever is a little rusty; that's all I can find wrong with it.

I had intended to mount my existing 'Frankentoilet' with the crossover sanitation pipe underneath this blue shelf; so the shelf is mounted a little higher than it would otherwise be.  Unfortunately this toilet's pump doesn't mount on the level; it mounts at a slight angle (like a modern Jabsco) on an angled flange on the crossover pipe.  So I can't mount this pump on the shelf, with the crossover pipe underneath, because it won't sit flush.  I have no idea why Wilcox did it like this.  I really wish I were reusing the original Raritan Compact Mk I; but this is similarly 'retro' and works fine-- and best of all the price was right.

The two little openings under the shelf are meant for access to the bolts; and this was supposed to accommodate the crossover pipe underneath so these would allow for cleaning out as well.

Behind the toilet the black ring is a Starboard trim piece around the exit pipe (PVC) leading to the holding tank.

The all-plastic Rubbermaid tool box is actually in its intended place-- this V-berth area has become a true forepeak, having room for only one to sleep but getting equipped with a tool box, workbench, hanging locker, microwave oven, plenty of outlets for charging cordless tools and possibly also a fresh-water supply tank for flushing the toilet. The holding tank is underneath, with most of the plumbing and all but one of the boat's through-hulls.  And that's in only the aftermost 26 inches of it! [wink]

The mahogany in the foreground is the backup to the compression post, underneath where the maststep really is.  It's a piece of the stock I cut for the cabintop handrails, but here it is solid except for only one hand hole (through which the vacuum cleaner's cord is running).  I gauged this hand-hold for someone sitting on the potty and only after installing the stick I realized that the head door's latch has to go at the very same elevation-- so when you reach through it you will stub your fingertips on the edge of the latch plate.  Oh, well.

At the time this was taken the lockers behind the toilet were taken up with the stereo, the outlet strip and the lift-out panels for all the lockers about the boat.

The bronze Barlow selftailing winch (vintage 1977) is a leftover from Warren Luhrs' C44 cutter and served as a doorstop in my mother's bathroom for about 20 years.  It's now slated to be the foredeck-mounted anchor-rode winch for a first-generation Hunter 25 called Diana.  Funny how things turn out!


Here is an 'aerial' shot of this space, minus the toilet, taken from the foredeck hatch opening. 

The door jamb, to the right, was excessively tedious.  It is a T-section and has to fit a very awkward three-sided space and accommodate the natural crookedness of the boat as-is.  It turns out that the face of the head's sink cabinet (side of the port-side berth's footwell) is neither in one plane (it's twisted) nor parallel to really... anything.  Fitting delicate mahogany (the lower portion of that stick is 5/16" square) to a crooked boat is an exercise in near-futility.  But I got it to fit!


The threshold of this doorway is somewhat more robust.  If it appears crooked, it's because the main bulkhead of the boat is not square to the centerline.  Believe it or not that threshold is in the only place it can be to make the (not yet built) door work.

I still have to countersink those screw-holes to fit them with plugs; but I'm keeping it as removable in case something happens with the door later.

The rough plywood sole is only temporary.  The finger-hole, however, will be in the finished mahogany panel.  It's the drain for the space, as there'll be a shower hose here too.


The black square is the pedal for the Whale Gusher foot pump for the head sink.  It feeds from only the port tank, however, despite being likely to be the most-used water source in the boat.

In the foregound (top right of photo) you see the coaming for the foredeck hatch, not yet varnished.

I like the deep-blue/white/black/stainless/mahogany decor theme of this boat.  It's bright, cheerful, nautical and traditional.
