Hello Roger,

Treat your aluminum decks with an aluminum etching product and then adhere
your teak decking down with either a SikaFlex or 3m marine adhesive. No need
to drill through water tight decks. Sprung decks call for a more creative
approach, either use clamps and weight or adhere
the sprung deck onto plywood and then adhere to the aluminum.

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
