A drifter is a really light reacher/asym. Because of the light material it dosen't take much wind to fill it.
If you could do a test sail (even if you drive down to pick it up at the same time) that would be the best option in my opinion. You get to see all of the systems in operation; sails, engine, blocks, etc. That minimizes any suprizes when you do get it back in the water. Then you would also de-rig it for the road, big help. When I purchased my stiletto, I drove to N.C. to pick it up going on only pictures. The pics were accurate though and I am well pleased. We only motored it a couple of miles to the marina where we hauled it out and de-rigged. While taking down you really look at everything which is a plus.
The 21 is a nice boat, great for traveling and camp/sailing or what ever as take down and setup should be much quicker than my Stiletto. That will make it easier when deciding on a short trip. I will be looking at taking it to Fla. next summer though, do a little cruise in Santa Rosa sound and maybe the gulf. I'll probably keep it there for a month or so then sail back to Miss. keep it there for a while then bring it back to LA.
Good luck, let me know what I can do for you.
