so you reckon a patch along the thread seam is possible? for the lazy option should I apply the Sika 291 to the outside of the thread, inside access could be tricky.
thoughts appreciated..

No problem at all! I HATE HATE HATE water leaks... I have probably fixed more water leaks than I have air leaks.
You would be surprised! Water is too large and cannot creep through the edge of the material like air can.
However, as the adhesive ages, it can allow a trickle of water to pass by...usually only a few CC per minute.
First off, I would encourage you to diagnose the location. To do this, simply plug your boat up, and fill it up with a garden hose like a bathtub, then simply watch for where the water is dripping out.
If you have one little drippy leak and want to do the lazy method, wipe the surface with acetone or toluene a few times to degrease it...tape off the affected area so you get a clean bead, then apply your Sikaflex. For caulking applied to the exterior, I smooth it down with a spreader. Sharp edges will catch water and cause the caulking to peel off. Really though, the best way to solve these leaks is by ungluing and regluing the bad section though...
