Thanks for the quick replies guys. The bottom is worn down to the fiberglass. I don't know that I need to be doing any shaping, rather taking care of the holes and reinforcing the bottom at the same time. The place I sail the most has some nasty gritty sand at water level. There is one area that looks troubling. It looks like at some point the was quite a hole in the bottom, about the middle of the hull where the point starts flattening out. It looks like someone tried filling it, with what I don't know. It appears to have worked, but I'll feel more comfortable with some fiberglass over that.

I will be using West Systems, and will be doing this in my garage. The temp has been fluctuation through the 50's and 60's here lately.

The advice I've been given so far was given by a guy who used to do these types of repairs for a living in Hawaii. He is a Hobie guy, "warned" me against getting a Nacra because it wasn't as solid, and so he thought it might take 3 layers. He said to sand about 2 inches around the holes, down to glass with a vibe sander. Then use 3 layers, getting progressively wider. Said to use the West Systems stuff, and said to use peel ply on the top layer to save some sanding at the end. This was via PM at a different, general topic forum, without getting eyes on.

So one long strip it is. Do you use any particular type of throw away brushes? It's been so long... Do you impregnate the glass on both sides or can you lay it down and then put enough on that it soaks through?

How much time do you think the normal hardener would get me at the temperature stated above?

*I guess I've never seen what the shape should actually be on the 5.0 to tell if it needs reshaping or not. Any ideas?

Thanks again for the quick replies
