double bilgeboards for a Spray 22

[BillEMac]

Hi,

This my first post. I am building a Bruce Roberts Spray 22. Both my plans on were I will be sailing and a better understanding of this design windward character, has got me thinking about redesigning the keel for better windward performance. I will be sailing for now and the forseable future on High altitude lakes in the western US, mainly Utah.

I am thinking about shortening the keel about six inches and adding fore and aft bilgeboards. This I would hope would give the boat good windward performance and reduce the wetted surface area. What do you all think?

It will change the righting moment and the tracking behavior. Also, with three foils the center of effort will be very variable.
