Bruce's boards are awesome. They will pull you overboard if you are not careful. Have a good secure place to anchor them
These are the design that Tawn used for his boards. Lolo also built the same set with great results.
My cockpit space is limited, so the smaller set works well for me. As a matter of fact, I bought Lolo's old set before he purchased his 36 footer
These work well for me, and can be placed on my roof if need be. I run 7 rods off each side
I have been able to "run" all small 9 inch umbrellas if needed. Of course, a "nasty" day would tax them to their limits, but "normal" days work fine.
If you decide on Bruce's design, you will be very happy.
