Title: Plank to Hull attachment
Post by: Atom Man on November 24, 2012, 09:40:16 AM
I have read the various post on this topic and am undecided on inside or outside attachment plates.  Looking for Pros/Cons for each system.  Also, with inside system, the 3/8" studes will need to be long enough to penetrate thickness of floor and allow installation of the nut.  What is the length of the Sarns internal mounting plate studs?  Making slow but steady progress on my rebuild.

Usually you drill a hole through the floor large enough for a socket (typ. 1").
The studs are only about 3/4" long.

This boat has a slot instead of individual holes: http://iceboating.net/node/29

Thank you for the picture.  It was very helpful.  I'm thinking that the internal mount is a cleaner look.

Think it's also stronger.

For a cleaner look, most of us drill 1 inch holes at the locations  of the holes on the alternate attach plates.

Most important reason to consider for inside mounts:

Water drains from cockpit.

Sailing in rain, through puddles, or melting snow, the water inside all runs out.  Result:  dry butt.
