[Public-List] Which caulk for cockpit teak combing joining to fiberglass?

[Gordon Laco]

Good morning Jonathan - 

I am guessing that in Option 1 you are referring to red oak.  That wood is not appropriate for marine use.  White oak, in complete contrast, is very durable, very close grained, and does indeed take finishes well.   

Both varieties of oak can be successfully varnished - there’s no need for ridges etc to remain if normal sanding and coating is applied.   But red oak will rot quickly.  White oak may last centuries if it’s looked after.

When varnished, white oak has a bright blonde colour… I’d say the only disadvantage it has is that it has a tendency to turn black if water gets through the varnish.

PS I’ve just discovered the on-line coverage of your club’s racing on youtube.  Saw you and your boat in a couple of the races. You certainly sail in heavy traffic sometimes!
