The hull deck joint is bonded together- there is no sealant. If the interior liner and or joint shows evidence of leaking, it is worth investigating. Is the material at the interior cracked/stained/showing signs of water entering? Photo is of bonding material at interior joint of hull #316. Note stains and cracks. The cracked material, in this case was smeared with some flexible sealant. The polyester/cabosil material was removed and replaced, removal achieved by cutting the material at the exterior of the joint with a 1” diamond wheel using a Dremel. Carefully cut the material between the hull/deck, not the part flanges. A ‘5 in one’ tool was inserted between the parts and with light hammering, the majority of the bonding material fractured away from the parts (hull/deck). Cabosil bonding material was removed from joint, the area was abraded with a nylon flex wheel to clean flanges while they were wedge apart for clearance. Syringe(s) were used to fill joint area prior to clamping flanges (do not over clamp and starve the joint of adhesive!!) In my case I used West System 655 adhesive. Joint was liberally filled from the exterior, then interior seam was syringe filled and faired to the interior deck and hull liner.

Lots of progress on my M17 #248 the last couple of days. In addition to bow to stern cleaning outside/inside I took off mast/standing rigging and inspected and all looks good.
I had some inspiration last night to use a heavy polish compound to the heavily oxidized hull to see how well it would work and 4 hours later the hull looks incredible. I’ll leave it as is for now with a polish/wax next spring.
The boat is going to a local sandblaster expert tonight for a bottom 3-4 layer paint removal. I’ll seal up a couple through hulls then put a bottom barrier on over winter.
I would like to reseal the deck joint since it probably is due for it. Any recommendations as far as that project is concerned?
Thanks
