How can you counteract heeling ?
about 35° for modern racing yachts which have been optimized for upwind performance ( like America 's Cup yachts ) about 40 to 45° for modern cruiser - racer yachts ( fast cruising yachts ) about 50 to 60° for cruisers and workboats with inefficient keels , inefficient hull shapes , or low draught , when compared to craft designed for sailing performance , and for boats carrying two or more masts ( since the forward sails adversely affect the windward ability of sails further aft when sailing upwind ) close to 90° for square riggers and similar vessels due to the sail shape which is very ineffective when sailing upwind Sailing close - hauled under a large amount of sail , and heeling a great deal , can induce weather helm , or a tendency for the boat to turn into the wind .
