In mast furling does cost in speed but seems like it might be easier for relative newcomers to the sport. No experience with in boom systems but I wonder about added stress on the gooseneck, they LOOK big & heavy. I agree with others regarding boat size, seems like a lot a boats never leave their slip and I think it''s cause the owners are nervous about getting in & out of the dock more than any other factor. I took some classes on 45'' boat with a lot of low speed operation, docking, picking up moorings etc. so anything smaller seems easy.
