"I should have added to the above that fumed silica is probably the best thickener for general bonding. A blend of cotton and silica is also great for wood."

Stern drain hole
6 Replies
I'm still getting to know my recently acquired Pahi 42. A few mysteries remain. One of those mysteries is the drain hole in the compartment at the stern. This is the area adjacent to and aft of the…Continue

"Here’s a quick reference for generic substitutes for the West System fillers:
403 For laminating/bonding porous surfaces. Milled cotton fiber or cotton flock. Maybe blend in some silica to reduce drips/sags. Great for plywood scarfs or…"
"That doesn’t look too bad. If you’re restoring the beams, adding a layer or two of thick glass under the lashings would help.
The plans call for smearing lanolin between the beams and the lashings. I haven’t done that on my boat."
"I built a new cockpit box last year. I needed a second pair of hands to move it, and we used the boatyard’s telehandler to install it. Jacking up the box and blocking it should be possible. Lifting by hand would be a stretch for me, but…"
"It depends on how the beams were built. If the beam tops are bare (unsheathed) lumber, I would probably do nothing at all. A little gouging from the lashings isn’t hurting anything. Placing metal or anything impermeable over the wood will…"
"Our Pahi 42 has a ramp, similar to the one in your photo, centered in the stern between the engines.
I don’t see how you could do it in the bow. The inner forestay bridle would be in the way."
"There’s generally no need to build a Wharram stronger than what the plans require. If you plan on keeping the boat for a long time, you should be attentive to protecting against moisture penetration, abrasion, and UV exposure. I’m…"
"I suppose it would be possible to fabricate the cockpit box without the rails. Then push it up from below until the top is a little higher than the beams. Then attach the rails."
"Regarding the rails as given in the plans, I’m not sure it’s worth following the curve of the beams. It’s difficult to match that curve exactly on the cockpit box. It would be easier to use straight rails and just add shims on the…"
"It’s usually possible to arrange for a crane. Our Pahi 42 fits in the local boatyard’s lift with a few inches to spare. Bigger cats are routinely lifted in and out with a crane. Our Pahi came with a set of straps that the previous owner…"
"I would avoid adding any extra weight aloft unless it is called for in the design. Hopefully the mast is strong enough when built as the designer intended. An epoxy primer and three coats of a two-part LPU paint should provide adequate abrasion…"
"I have also enjoyed reading through the old Sailorman/SeaPeople issues and found a lot of useful and interesting stuff.
That spirit isn’t dead. It’s just moved on to newer technologies. The Wharram group on Facebook is very active,…"
"I don’t think durability is a concern, but heat should be unless you sail only in cold climates.
Our light grey nonskid decks are very hot in the early spring sun of south Florida. By summer any non-white surface is too hot for bare…"
"I am also rebuilding the boxes on my Pahi 42.
Would suggest avoiding chopped strand because of poor strength to weight ratio. Skins of woven cloth on both sides is a good idea—especially for water and abrasion resistance.
In fiberglass…"
"I have a Pahi 42, but I think the usage is similar. I do not tilt the engines. I want them to be ready to go quickly if needed: lower the sleds, prime the fuel, start. "
