Profurl
The Profurl line is great for cruisers-it is not quite as nice for racer/cruisers who want to go back and forth from one mode to the other. Not as adaptable as Harken, for example in that respect-especially the "basic". My understanding is that the basic system has only one groove on the back side for hoisting the headsail, and the classic has 2 (like Harken or like a racing boat headfoil).
This means that with the basic, you can't do an in-line sail change (hoist the new sail on the "free" groove before the old one is dropped-this way you are never bare-headed).
So, the basic is strictly for cruisers, the classic better for racer/cruisers-the main difference is the extrusion.
Why do you say that furlers for lake sailors don't have the same demands as ocean sailors (I assume you mean Great Lakes). Unless you are on a small, inland lake, "offshore" is "offshore" whether you are on Lake Michigan, Superior, or the Pacific or Atlantic ocean.
IMHO, anyway,
Cheers
