: Hi again John,

: How 'bout that, Hobie either sold or made a windsurfer, learn something new
: every day :)

: It's called an Alpha, think perhaps they sold it and someone else built it,
: but unsure. I saw a couple pictures and the rig looks about as old as the
: one I bought, ie: antique :)

: Good thing is it's a low pressure rig, much lower aspect than the modern rigs
: and uses much less tension to rig the sail. Down side is it isn't anywhere
: near as powerful as a modern windsurfing sail. For our uses though this
: isn't a bad thing, it's a well cut sail that tends to hold it's shape for
: a long time and can have multiple uses. Think you'll be happy with it.

I went for my third shakedown cruse yesterday using a GPS for testing my poly tarp sails for speeds in modest winds of 10 to 20 mph. My best speed with just the main was 4.5 mph. The main and jib together was 4.2 mph and sailing with the jib alone was 3.5 mph. The jib has a nice camber in it due to the generous rounding of the luff and foot plus two darts sewed in and looks nice. I wonder about my main though. It looks too flat and the only camber was produced by some of the very little rounding of the luff and foot. I think I am loosing some power from the main being too flat and the e-bay sail should tell me something about this I think.
