Persistence
whatsits?


The devil is in the details

BOO! Give up? Actually, this odd-looking thing is the author's custom-built wooden seat, fitted in the companionway.The circles are for his, er, seat and are custom fitted. The holes let out water, if any comes aboard.

Whatzit? Passersby often wonder what this is. Actually, it's a deck prism inset in a cast bronze mount. It gathers light and disperses it below -- a favorite of the author's, particularly on dark days.

A pint-sized expresso maker sits atop a butane stove, with copper tube leading to metal coffee cup. Cup contains mixed instant milk. When cruising onboard Persistence, the author enjoys latte every morning.

Look deep in the water: it's a sort of fin protruding aft. The author likes the fin and the bulb at the rudder tip to control heavy weather wave action. He uses the tip at a foothold to get back in the boat when he sometimes falls in.

Home-built wooden bows fit atop the sea hood. When in upright position (shown here) they hold up a companionway dodger, just big enough for the author to sit on his wooden seat. When not in use, the Sunbrella and plastic hood comes off, and, the wooden bows fold forward.

Inside the tiny cloth and plastic dodger (just big enough for the author's head and shoulders), the boat can be operated out of the weather. GPS is on right, compass dead ahead, and clock to port. A folded chart hangs from clip for easy reference, and,

Building
Persistence


The hull and cabin are nearly completed. Boat is on its building stand.

The author began building Persistence in 1979. Here he works on the sitka spruce stringers.

Most of the boatbuilding was done outdoors, beside the author's home in Shoreviw, MN. The stem and keelson are white oak, and, the stringers are Sitka Spruce.

Length overall is 20 feet. Boat was built atop a strongback.

The first of three layers of 1/8-inch thick wood veneer strips is stapled and epoxy glued to stringers. The hull is finished off with extra coats of epoxy and is of monocoque construction.

Early interior construction. CB trunk in foreground, and, the portside "nav" station, under the heavy lexan portlights, which are through bolted. Forward is the large V bunk. Note how the CB trunk is encircled with frames and carlins from the bilge to the mast step, making the little boat very strong.

Glass cloth covers the veneers and becomes transparent under the epoxy.

Das Boot: The Boat

Marlin adjusts the folding hatch dodger onboard Persistence.


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 of NautiThane. The boat was sanded down and then recoated in 2007 with the two-part clear polyurathane finish.

The unique Artful Dodger I designed for Persistence has a demountable canvas cover in four pieces and sits atop wooden frames. The whole thing is tensioned by straps leading to the hatchway and when not in use folds forward, out of the way, a lot like a baby buggy top.

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. New in 2007 is the tanbark 5.2 ounce mainsail complete with single-line reefing.

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. CB is epoxy/​graphite coated and swings on a 6/​8-inch thick Silicon Bronze bolt running through case logs in CB trunk.


Coming about, the boat is easily sailed single handed.

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.

On its way north to Superior, Persistence rests securely on its trailer, its forward section protected by its cover. Loris stands beside small boat, towed by the author's 4 x 4 Suzuki Sidekick. The Kick's 1600 c.c. engine puts out 80 h.p.

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.

Inside Persistence, the author sits on the forward V berth to operate the nav station. In front of him is a ham-band radio and (top left) the VHF. The boat also carries an EPIRB. To the right is the CB trunk.

The deck is teak, and, the cabin top is Honduras Mahogany. Note sea hood over cockpit hatch.

Under Cover: Boat cover totally protects topsides of Persistence. The cover is used when mast is up and also protects boat when mast is down, for winter storage. Note boom tent.

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.

With Superior in the distance, Persistence (right) waits out the aftermath of the Green Storm on tiny Thompson Island's harbor. (photo by Clive Dudley)
