This should be the last of the significant changes. It does look better even.

Courage Winter and his family are cruising in Costa Rica on the stretched KHSD 53′ catamaran known previously as Jack’s Old Boat. What a great school for kids.

Gel Magic

I have been using System 3 Gel Magic for my bogging jobs for a while. http://www.systemthree.com/store/pc/SilverTip-GelMagic-c16.htm
The resin part is blue and I call it Smurf snot. Apparently you have mixed it enough when the color goes away. I mix even more just in case.

I especially like it over epoxy and powder mix for two reasons. First, I am able to mix something like twice the bog volume in a given time because I don’t have to take the time to mix in powder. And if you throw it at some part’s vertical surface, it just hangs there, not dripping.
I had been using regular hardner and it was going off too fast in even just 70 degree days. I finally got the extra slow and its just what I needed working by myself on the project.
Interestingly, if you add any powder, the “just hang there” goes away and it slumps. For that reason, when I extend it with spheres powder, I also add cabosil.

Alex’s New Mast

Alex just got his all carbon fiber, rotating, unstayed Aeroesque mast from Jim Betts. I hear it will be stepped soon. He is building a 45′ KHSD cruising cat; kind of a smaller Sarabi 56′. Bellingham, WA.

Plywood/epoxy. The work looks great.

Online Metals

I often end up going to Online Metals to get metal or plastic bits. Easiest place I know of to get that 3″ x 3″ piece of teflon, or whatever. On the ship canal here in Seattle so especially easy for me. http://www.onlinemetals.com/productguide.cfm
