It always interests me how the different boats all have their different wind ranges and angles, and how different they can be. For mine, I'm terrible in the sub 5 knot range, I might as well be towing a drogue she's that gluey. Fusion seems to prefer 25-30 knots at 110-130 twa where she settles down and becomes finger light, as long as the sea state isn't too short and sharp.
I remember being out one day in pretty high winds (25+) when nearly all the boats were running little or no sails, and there's Boty with a full wardrobe, not a reef in sight, just trucking along as happy as a lamb.

We're going to stretch her legs after work tomorrow if anyone's keen for a twilight sail? Should be fun!
PM me if you're keen, we're not exactly weight conscious in these forecasts

So what's the sweet spot for your boat?
