Here's a screen shot of the Storer GIS Lug sail as rendered by SailcutCAD. The slider bars left and bottom rotate the image about the horizontal and vertical axes respectively. It's a nice feature because it helps to visualize the shape by moving it. I'm posting this mostly to test the process of taking a screen shot and uploading it to the blog. I'll jump over the the forum next and repeat there. Time will tell whether I duplicate all entries in both venues or use this blog for the nitty gritty detail and just "announce" the latest on the forum. The drawback to that approach is that lots of great discussion gets generated there, and I don't want to dampen that collaboration.
Howdy,
ReplyDeleteOne suggestion is that I already have a sail design for this boat. It doesn't use broadseaming and one hasn't been made yet.
However it builds on information from the lugsail developments from the OzRacer (formerly OZ PDRacer - made in polytarp - not a good idea for a fast and powerful boat like the goat) and the sails for the RAID41 (which were dacron)
I can give you the drawings I have which might give you allowances for the round you will need to account for spar bend.
The RAID41 homemade sails looked pretty good. Maybe a touch flat but not too bad for a first shot

And using that info would give you a head start.
