The pane;ls stay pn the table for 24 hours so the finish does not get damaged.   They are definitel;y stiffer after a week, but was no trouble bending.  The lee hull decks are 2"/50mm radius.  Could have gone much tighter, intend building the rudder blades from a single piece, folded to shape.  No cracking on any of the boat, or samples.  Glass/resin is remarkably tough stuff.

Rob,


I also have a couple questions I have been meaning to ask.

Do you need to do the bends before the epoxy has fully cured, or can you wait a week to bend the panel?

What radius can you bend through? I am worried about the fibers cracking when you do the bend.

Thanks,

- Gardner

Hi:

I've taken a look at the solitarry2 construction pictures. They are very intriguing. I have never seen his construction method before.
It seems like a "bend and glue" technique versus the traditional "stitch and glue". I have the following questions:
1) What is the material glass, epoxy, poliester, foam (what thickness?)
2) Why is a rounded bottom better than the flat bottom I would get with stitch and glue?
3) Why is the lee hul split in two halfes?
4) what is the circular whole in the ww hull for?
5) Will the ww hull have tight bulkheads to make it insubmersible?

One general quation as well. The absence of rocker in the keel, is that a dessign advantage or is it for ease of construction with your building technique?
