Alan,
The snap-roll issue only becomes a problem at higher speeds…way above anything that Frank can expect from his well-designed boat (unless he has figured out how to install a warp drive for a compact power system J). If I remember correctly, there was a SNAME paper in the mid to late 80s that covered the issues with sails and snap-roll forces.

Thanks people, thats something more that I didn't know.
Frank maybe you could utilize this, & put a fin on top (like the comb on a chooks head)
Then there'd be less sideways slide & you'd get that tilt on cornering. It may be an advantage as you'd
get a better view of anything below that you're circling round.
You could always attach something temporarily & try it out.

Hi Sean. I always thought the "snap roll" was to the outside of the turn making the big nuke subs lean out when turning sharply. Thanks for the info. It's very interesting how submerged objects react to the flow as compared to a surface boat. Frank D.
