Ask Sail

David von Fruke of Ssen, Minnesota, asks: “Last year I purchased a 202 ft2 asymmetrical spinnaker for my Hunter 170 along with a sock for dousing the sail. My goal is to set the spinnaker singlehanded, and while I can manage it, I do have trouble raising and lowering the sail. I have been thinking about putting the spinnaker on a roller furler. What do you

When we acquired our “new” boat I saw at a glance that the plastic-sheathed lifelines were junk. Not only were they too thin–she had been used only for racing, so I guess the wire was underspecified to save a few pounds – but they were all too obviously old and dangerously corroded. I once saw a friend fall overboard because a rusty lifeline gave way, so I knew I would replace them as soon as

If you are one of the many thousands of sailors who own a boat built before lines-led-aft became ubiquitous, and you want to be able to sail your boat without leaving the cockpit, leading halyards and reefing lines aft can be a relatively easy upgrade.Planning the projectStep one is to look at the feasibility of locating the hardware you’ll have to add. Your deck

Chet Sturgis of Chicago, Illinois, asks:”Recently, I installed a cell phone amplifier—I don’t recall the manufacturer’s name—to increase my range when I’m sailing off the coast. Although range has improved, when I’m back in my slip I can’t get good reception from someone who is calling me from just several hundred yards away until I turn off the amplifier. What am I doing

Pete Ward of Wilmington, North Carolina, asks:”The packing in my stuffing box has become so tightly compressed on the shaft that when I put the transmission in gear, the whole thing turns in the rubber hose that’s connected to the pipe going through the hull. I’ve tried to get all the old packing out with a hook, but it’s still there. I don’t want to use a hammer. Can I

Stuart Goldman of Shelter Island, New York, asks:”For the last two years the zincs on the shaft and MaxProp on my Hinckley SW 42 have started to really dissolve in early July—after the boat has been in the water for about a month. The boat is on a mooring that’s at least 500 yards away from any other boat except a 50ft powerboat, which is also on a mooring about 50 yards

Terry McCoy of Gainesville, Florida, asks:”After running perfectly for years, the diesel engine on our Beneteau 331 stopped running when we were backing out of the slip. It started right up, but then stopped again—and again. I changed the fuel filters and the engine ran without a hitch until one day we were returning to the marina and suddenly it quit again. Although it

Philip Donegan of Kemah, Texas asks: “My 35ft boat has a 379 ft2 mainsail. I’m using 10mm braid for my reefing lines, but I am thinking about replacing them with smaller Dyneema lines on the theory that the smaller diameter line will reduce the friction on the blocks. Am I correct, and if so, what is the minimum line strength I can use?” Win Fowler

Jim Fischer of Ellicott City, Maryland, asks:”All the bronze seacocks aboard my 1979 fiberglass 34ft sloop are connected to a keelbolt, along with the boat’s lightning ground system, which is also connected to a keelbolt. Is this still the recommended arrangement, or do you think all the seacocks should be isolated from each other and not connected to a keelbolt? Can I

Don Glynn of Westlake Village, California, asks:”My ground tackle consists of 30ft of 5/16in galvanized chain, 270ft of 5/8 in three-strand nylon and a 22-pound Danforth anchor. Recently I discovered a 20ft hockle in the middle of the 10-year-old nylon rode and assumed that the kinks occurred after being coiled many times, and the boat circling around the anchor. I am
