Das Boot: The Beautiful Boat

Some details of the author's historic sloop that he built himself. (Note: Click on photos to enlarge them). Special notation: How Persistence survived "the storm of the century" on Lake Superior, see Secrets of Persistence's Storm Survival (below)



Though only 20 feet in length, Persistence is well outfitted. The author lived onboard for up to three months of cruising. (Click on image to enlarge)

From this inside steering position, I can set Persistence up to self steer. Note GPS, chart, captain's seat and remote control for an autohelm, located aft on the tiller. The Artful Dodger covers all as needed, although the side panels can be demounted for ventilation on hot days and a back panel with clear plexiglass insert can be rolled down to completely enclose the solo sailor in heavy weather.

Persistence glistens under a repristinated finish. The boat was sanded down and then recoated with a two-part clear polyurathane finish. This view from aft shows the instrumentation, the tiller and the 5 horsepower outboard engine.

Details of the author's 20-foot sloop, Persistence. The sloop is set up for singlehanded sailing with all sail controls leading aft to the cockpit.

Three anchors: main Danforth with Chain in first 10 feet, smaller Danforth "lunch hook," and 10-pound "mud" anchor of mushroom deisgn. / Design additions: Folding lcoth dodger fits over companionway, so author can sit sheltered inside and operate boat. Portable seat fits under companionway. Transom was lengthened with "scoop". Six-inch deep stub keel added through which 3/8-inch thick steel centerboard slides up and down.

SECRETS OF PERSISTENCE'S STORM SURVIVAL

 

"If she ever goes over, she's not coming back up. You'll have to be careful out there," was the advice I got from the boat's designer. But yet Persistence capsized many times, including mast tip in the water, and yet the small craft righted itself and survived to sail on with the author at the helm. Persistence is not a keel boat -- one of those sailboats whose stability relies on a heavy lead keel far below the waterline that amounts to nearly 40% of the craft's weight. So how did the little sloop withstand the heavy pounding of the Green Storm and other bouts with Superior? The answer, the author believes, lies in his careful building which selected the heaviest woods, such as layered inch-thick white oak for the keelson, and, the lightest woods, such as Sitka Spruce for the topsides deck beams. Overall, the craft is ultralightweight with its Western Red Cedar hull planking and cabin tops. Thus, I had some weight down below, though it was not a keel. I also mounted two heavy-duty marine batteries directly atop the keelson, which added another 100 pounds or so. As an added precaution, I managed to change the righting arm by constructing the cabin to be within inches of the outer deck, so that when the boat went over, it would not "flop" into the water, such as it would do if the cabin were further back from the beams. I added an inch-thick Sitka Spruce rubrails to each side, tapered at the front and the back to give the sheer a little more grace. These wooden rubrails acted as a sort of "life preserver" around the hull and not only protect the hull from damage from docks and other boats but add floatation in a big way when the boat gets knocked down. Also, after having an experience with a sailboat which capsized and lay on its side as water gurgled into its mast and finally turtled, with mast full of water and pointing straight down, I decided to foam parts of Persistence's mast. I took off the crane, topped the uppermost section of the mast with spray in foam, replaced the crane, and then methodically went down the mast and drilled a tiny hole wherever the mast had a piercing for a part, such as the spreaders, and sprayed in more foam, using the small plastic tube that comes with the spray in foam. The result was that the oversized aluminum mast now had a significant amount of floatation in it, which came into play several times during the dangerous "Green Storm" encounter when the boat did flip over in high winds and the masthead did enter the water (and water sloshed up through the centerboard case, to my horror). What else helped us survive the storm of the century? Before I entered the open waters of the world's largest freshwater lake -- more of an ocean, really -- I always check the craft carefully for closed hatches and vents. I also move all gear out of the bow and the stern as much as possible, and secure with bungee chords these duffle bags, sleeping bags, toiletry cases, cartons of goods, tools and supplies, alongside the centerboard case, which is in the center of the cabin. This keeps the weight out of the ends, especially the bow, which can dig into waves in heavy going, by making the ends lighter. When the first blasts of the Green Storm arrived, I knew I had a well prepared boat and immediately resorted to heavy weather sailing tactics by taking the initial wind blasts on the stern, rather than abeam. Trouble was, I then headed out into Superior far from shore and would have to ride out the storm until the first raw (and very heavy) blasts subsided and I could turn the boat (hopefully) back into the wind and back on course to Thompson Cove, a small island where a tiny harbor of refuge lay. Part of our dangerous survival lay in the fact that I had taken sails down and secured them on the boom and on the jibfurler and was now running under 5 hp. two stroke elderly outboard engine. The engine took a terrible beating because part of the time its prop was out of the water, with no cooling water being pumped into the engine head, because the boat lay on its side, capsized. Later on, when I returned to my home in Shoreview, MN, I took the engine in for servicing and checkup and told my mechanic that I was interested in getting a new four-cycle engine. "If you had a four cycle out there," he announced, "you probably wouldn't have made it back." I still have my two cycle outboard, for that was yet another important link in my survival during the Green Storm.

Leaning out, the author finds his mast crutch a handy convenience in the cockpit. Bree has lived aboard Persistence for as long as three months while cruising Lake Superior.
In gin-clear waters, Persistence floats easily in CPR Harbor, on a small island in the northern arc of Lake Superior. The visit to the harbor is described in the author's book, Wake of the Green Storm.
The deck is teak, and, the cabin top is Honduras Mahogany. Note sea hood over cockpit hatch.
At Sunset, Persistence is snuggled down deep inside a harbor in the beautiful Slate Islands. In a few minutes, the author will see one of the islands caribou on the shore.
