On the other hand, the Harpoon hardware is simple and straight forward. It should not be too difficult to get most of what you need from any sailboat shop. For replacement bailers and bailer gaskets, you can contact Joe Sivore at Andersen U.S.A., a Fort Lauderdale, FL distributor of Elvstrom-type bailers. You can also subscribe to the newsletter. I had my 20 year old Harpoon Sails cleaned and re-resined by SailCare and the result is nothing short of astonishing.
Some sailors have their sails treated every winter.
While this is not necessary from a day-sailing perspective, it is certainly worth considering if it has never been done rather than ordering new sails. SailCare also does a terrific job repairing your sail. This particular company had the lowest prices I could find. Of course, Harpoon sails can still be optained from North Sails, the original provider of Harpoon sails. For top performance and handicap racing, you will undoubtedly get the best result with a good suit of new sails.
