I want to fit teak decks to my 37ft aluminum sailboat. Does anyone know
whether I can fasten from below, to save all that tedious plug cutting,
fitting and sanding?
I thought that with aluminum it would be quite strong if I drilled from
underneath - the fasteners should really only be required until the
bedding
compound sets.
Any thoughts? Thanks

You have a watertight deck now, don't drill through it, glue your deck down
to your aluminum decks
To glue teak to aluminum use an aluminum etch primer first, then either 3M's
5200 adhesive or similar Sikaflex adhesives. Sikaflex has a new
caulking compound called 290 DC that are made for use with teak.
Granted, a sprung teak deck takes a bit more ingenuity to lay when relying
on weight to hold it down until set.
Other option is to glue plywood onto your aluminum deck and then hold a
sprung deck in place with a screw and washer in the caulking gap until set.
