Do you have any photos of the repair that you can share? If so I'd like to have a look, please Dwight Veinot C&C 35 MKII, Alianna Head of St. Margaret's Bay, NS _____ From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Tim Goodyear Sent: January 11, 2013 9:59 AM To: Dennis C.; cnc-list@cnc-list.com Subject: Re: Stus-List Keel stub cracks The cause of the cracks was wet core just outboard / above the solid glass at the turn of the bilge (right by the mast step). There was a void between the mast step assembly (glass) and the hull proper that allowed water to sit for a while (29 years?) against the inner laminate... I now have full confidence in the hull integrity (having replaced most of it over the last two years), but am many dollars lighter. The temptation of a new boat is growing.

I've re-tabbed most of the bulkhead/hull joints in Touche's forward section. A few were detached or broken but most were just bad practice. When I had the boat hauled about 5 years ago for a barrier coat, I could see cosmetic cracks in the matte once the gelcoat was removed from the underbody. These cracks aligned with the bulkheads. The bulkhead tabs had no fillets. They were all 90 degree joints. This created stress points at the joints which manifested themselves as the cosmetic cracks on the outside of the hull. I have been re-tabbing all the bulkheads with filleted joints. I ground out the old tabbing, created fillets and re-tabbed with 4 inch biaxial tape. To create the fillets, I put thickened epoxy in the joint and smoothed it with the back of a plastic spoon. This creates a nice radius for the fillet. The filleted joints spread the load. This is particularly important in the forward section of the boat as that's where the boat pounds into waves. Dennis C.

I'll have that ground off and reattached and will add glass on the outside and fair. Does anyone have access to any of the original layup schedules in that area? I have copies of all the drawings that were available, but none were that specific on construction methods.

I was checking on Mojito this morning, and noticed beads of moisture in two areas; a spot at the top of the keel trailing edge and an 8" hairline crack on the port side at hull / keel stub (almost exactly where the mast step is internally). Would this have been enough for you to go ahead with major keel surgery? Rear of keel I've been trying to resolve this for a while; two separate boat yards have had a go at if, and the area is now solid fiberglass / epoxy, but still a tiny crack / area of moisture. There was water in the bilge just aft of the rear keel bolt (I removed the floorboards and sponged the area dry). Water would not normally stay in that area, but the boat is tilted back a little on the stands. I have not had the keel bolts torqued in 7 years (since I bought Mojito). Mast Step area This is the first year I've noticed moisture in that area; there have been hairline cracks in the antifouling before. The mast is stepped and I can't access that area through the mast step, which appears sound.
