Hi

B. I think it will be a good idea if you could show us a few foto's.
What you plan to do could be wrong or right it is very difficult from
your description to say.
But how long have the boat lasted allready ,maintained without epoxy --
you say that two seames are caulked ; witht what cotton or oucum and
how wide are the seams ?
Are they correctly cauked or is it an amaturs attempt to widen the hull
without knowing the right way to caulk . I think it is perfect with
Epoxy and new wood but I am not sure it realy is the right treadment
,if any "treadment shuld be advised consider how many years it worked
without epoxy, beside epoxy work best if the wood are bone dry -- is it
,can become real dry ?
Now if the seams realy are the result of over caulking , then maby a
routered in and epoxy glued piece of wood are much better and it could
happen that you would be much better off, buying a small hand held
router with copyer flange, --- when you get used to it you proberly can
use that for just any repair, and be able to repair the way these
boats shuld be repaired, the boatsbuilders way.
