Badgered Cat Posted January 6, 2018 Report Share Posted January 6, 2018 Hi everyone. When Grady McNee delivered my sails I purchased from Mark Colecliffe, just a few weeks ago. He advised me with the Mark 1 maricat, which I do have, to strengthen around the gunwhales, where the side chainplates attach. I have not done this as yet, as I wanted to sail over the xmas New year. Now he made mention that the NSW guys are unbolting the alloy plates from top and below the gunwhale, and then laying up extra fiberglass on the external perimeters, and then placing some stainless steel strips on the top and bottom before putting the alloy plates back on with larger size saddles. Well today I sailed in fantastic conditions with flat water and wind ranging from 0 knots to 20knots. And gee whiz at 20 knots of breeze fully powered up, and hanging over the back beam was exciting. Including passing a Nacra 36, like it was still in the water. Anyhow at the ned of the day, the boat was getting slower and slower, and when I got to shore the starboard hull was half full of water. Well I should have listened to Grady, as the chainplate had pulled the gunwhale upwards, and fractured the glass and gelcoat under the gunwhale in a big way. I am very lucky not to have ripped the side out of the boat. So now comes the repair job. I guess I need to remove the chainplates, and the rubber molding. Try and separate the gunwhale join a fraction, maybe epoxy that join and clamp back together. Then open up the fracture under the gunwhales with a dremel tool, lay up some glass over this fracture and under the gunwhales, with polyster resin and chopstrand mat. Then fair it back to a smooth finish and a layer or 2 of flowcoat. Then on the good hull lay up extra layers of glass under the gunwhales at the chainplates. What are the guys using for the stainless,steel, and have I got the correct procedure in place for doing everything. I dont want to do the wrong thing here. I am a skilled and qualified fibreglass worker, with many years in the past gone by, building Kenworth Truck bodies, and before that, building Fibreglass Bathroom fixtures. So all help and advice appreciated here. Many thanks David. Link to comment Share on other sites More sharing options...
