Bill, I'm going to be cutting away part of the foredeck on Kinesis, back a couple of feet from the bow around the cleat. Regarding your primary winch deck recore, why did you make a second cut in the skin and have that strip along the edge? How close should I go to the toe rail before I get into the hull and deck seam? I read your blog, but couldn't quite visualize how the boat is constructed close to the toe rail. Your blog and photos are a great help. Thank you. Sam

Sam,

The reason I made the 2nd cut is the 1st cut was too close to the edge. There is actually an angled lip molded around the seam of the boat. You can see it from underneath. I stupidly cut into that lip when I should have just measured and cut about an inch further inward. The core edge by this lip is actually angled about 45 degrees, rather than the outer core edge by the lip being vertical.

So - look underneath to see the edge by the seam and measure the width of the lip, then mark topside and cut there. You can easily dig out the core if you have a little overhang of the skin over the lip.

Great. Thanks.

I haven't updated my blog, but did do some work to reglass and recore near the aft end of the keel. Last summer after the NAs, one of the co-owners hit the ledge off Barrington YC dock. Below is a sequence of pictures showing the damage, temporary repair last summer, and final fix including repairing a much older problem due to a grounding that must have happened earlier in the boat's life.

hey bill,

how far back from the keel does the coring start. I've cut a 3 x 8 rectangle from my hull about 4 inches back from the keel, pure fiberglass. How far back to hit the core?

thanks!

Josh,

The center of the boat is all glass. That is where the two hull halves were molded and joined together. It is about 6" wide. You need to go outboard to hit balsa core.

that makes sense, your pictures make a lot more sense in light of that

Wait ... that makes two J/30s zonked at that surprise rock off the Barrington YC Fuel Dock? within 10 days?

[Bill, I wondered what you were doing now that you thought you would be retired.]
