Wally, I have the CDI-II roller Furler on my h23 with a 135 Gus Sails Genoa
I race mine all season. I have been out in 35 knot winds, gusting to 50 with it.
I had the main lashed to the boom and about 3' of my genoa pulled out.
With low wind I can compete in the races single handed
On a run with my Genoa on a whisker pole running wings most crusing boats in "A" fleet with spinnakers under 30' do not outrun me
If this were a race boat I would not have a Furler on it but it is not a racing boat
It is a strong, fun, easy to sail boat that wins races when you learn to sail your boat to its capabilities and strengths. Not the J-boats strengths
Alan told me that and when I started doing that I started winning alot
I single hand alot and race single handed alot
Without the furler my son would not have gotten his high wind sailing lesson that day.
I have pictures of my furler in my profile if your interested. Good luck, Charles
