I'm not sure that slugs are going to make your experience any easier. They are very good to have for a boat in a slip or on a mooring, where the sail is kept on board. They make it easier to flake the sail on the boom. That being said, I used to flake my bolt rope main on the boom for lunch stops all the time. A bolt rope will allow better sail shape. Slugs will not really make it easier to reef, either. What does make it easier to reef is have a Wave Front Marine Tiller Clutch on the tiller, to allow you to reef while hove-to. (I used to have a Harpoon 4.6, very similar to the P-16. If you have a reefing hook on a fixed gooseneck, I would make sure the sail loft puts 2 welded rings linked by sewn webbing into the tack reef point, to make it easier to lower the tack, fasten, re-tension the halyard, then tension the leech. Also, I ran my leech reef line forward on the boom to about 18" behind the mast. That way, I could turn from setting the luff and have the leech reef line right at hand. I think a loose foot main is a no-brainer, as it will allow you to see how much draft you have, and draft position easier than a bolt rope foot. Also, specify a draft stripe about half way up the main, again to see draft position. Look for a sailmaker who will discuss your sailing style and sailing area. This will help with the design of the sail. Also, if they aren't local, they should send you measurement forms so that you can get exact measurements of the rig, including things like tack reef hook position, etc. I chose Judybsails.com because of these reasons, and Judy is experienced designing small boat sails. For my Harpoon, I had chosen a sailmaker who reportedly made winning sails for a Harpoon 5.2, and who also raced Buccaneer 18s. My sails for the Harpoon seemed ok, but I didn't receive the level of measurement support, cloth options, and discussion that I got from Judy with my 192. I have not had experience with the sails here at Sailboatowners, but buying from them would certainly support this forum. You could contact Precision Boat Works, and they could tell you who the OEM supplier of the sails was, and contact them for a suit. They would at least have the sailplan drawings and measurements from Jim Taylor.
