Sailboat Hardware Attachment

by Bob
(Brewster, MA)

I am building a plywood optimist pram.

I am at the stage of attaching various fittings.

They are screwed on.

Should I uae some kind of bedding/sealant under these fittings?

If so what should I use?

Lining the fastener with epoxy.
by: Harry

The best way to prevent water entering ( wicking ) along fastener threads ( screws or bolts ) is to drill oversized holes for the intended fastener , fill with epoxy and let fully cure.

Drill a smaller hole into this epoxy plug to drive the screw , or same size hole as the bolt ( snug fit )then fit the bolt.Bed down with gray butyl sealant / caulk.

Butyl tape is less messy than tube.

This is known as fastener bonding.

It is described in detail by the " Gougeon Brothers on Boat Construction " book , they have recently made this text available free online .

An excellent text , can highly recommend.

Good luck.

Bed the Fittings
by: Mike

Yes Bob, it’s always a good idea to bed the fittings especially on plywood.

The screw holes are a potentially a route for moisture to penetrate down through the piles/veneers.

You’ll find some suggestions here >>>>
