Swagman,
Thanks for your advise and great explanation of the forces involved with end boom preventer and mid boom sheeting. It makes perfect sense!
I also like the idea of a strong (velcro) mid boom strop to attach the preventer lines to. Also sounds like you are familiar with the Bavaria 36, and that is comforting when considering your advise. I am now also going to investigate a boom brake (Dutchman).
Hopefully I will not experience the windward or the leeward broach! Neither sounds like a whole lot of fun, thank you very much!
Thanks everyone,
Tom
