Sails:
Sails are not made of iron; neither are they made of rubber. Canvas, especially when new, should be treated with gentleness. It is very easy to spoil a sail. More bad sails are made by yachtsmen than by sailmakers. When bending a new sail haul it out along the spar hand-taut and lash it. Then let the wind stretch it out, you taking up the slack day by day. As it comes, you can put more strain on it until it reaches its proper place. In damp weather, ease it in at the head and foot.
