The fuller one is an older Glaser, from about 4 (?) years ago. The flatter one is about 1yr. old Landenberger.

The fuller one is easier to keep from stalling, but as I said before, you can't go as high with it to get the hull up in light/medium wind, where as the Landy is much easier to "heat it up" and get going after the set, get a hull up and get cruising. But when it's really blowing, I don't sail on one hull.


The times I've tried to go on one hull in big wind, I seem to stuff it to the mast too often, which really slows you down, even if you don't go swimming. I've found it's more 'productive' to sail it deep on two hulls and jump over the waves rather than plow through them on one hull and stuff it to the mast.

But in medium wind I want to be on one hull all the time, upwind and down, so the flatter spin works better for that.
