The Shot Wing

Aerodynamic Ballast

This post is filed under the “where the hell is my flying car?” category. It is an aerodynamic and hydrodynamic balanced sailboat where the force vectors of the foils balance each other out at all wind speeds, creating a sailboat that is theoretically capable of the speed of light. I drew this in 1985, after reading about Bernard Smith’s “fliptacker”. This version is what you get when a budding industrial designer gets his hands on it. I called it the “Shot Wing”, which explains the stylized “S”.

Hit the jump for the tacking procedure.

Scooters!

image

Ice Scooters are a fascinating species of iceboat, evolving out of the primordial ooze of Long Island’s south side bays. From the South Bay Scooter Club:

The evolution of the Scooter is not well documented. It did not evolve from a designer’s drawing board nor was there a class association. It evolved out of necessity. Something like this. Take an old duck puntie and add runners. A mast, sprit sail or gaff and a pike pole to steer her. Angle the runners (bevel) to bite into the ice and to prevent the boat from sliding sideways. Add a jib to balance the main sail and a bit of rocker (curve) to the runners to increase steerage and you have a Scooter.

Scooters have a charming form factor and are certainly the most “boat-like” of the iceboats. In their early evolution they were capable of sailing equally well on soft or hard water, which must have been very useful. The inevitable racing led to lighter and more powerful boats that were no longer soft-water worthy, but they soon developed a new sport - jumping the water holes at high speed!

Scooters are steered by weight shift and sail trim, since they have no rudders. In that sense, they are like Oceanic proas.

The scooter, unlike other iceboats, is rudderless. She is steered by her jib. By trimming or slackening the jib one can change course. To head up, ease the jib and trim the main. To bear off, trim the jib and ease the main. Shifting your weight forward or aft accordingly accelerates the process.

The boomed jib evolved into an unusually low-aspect ratio, aerodynamically balanced “air rudder”. So not really rudderless after all.

Surfriding on Bamboo

Last week I received an invite from Scott V. of the Ravenna Tiki build project to come visit, and I’m glad I did. This Tiki 21 is a collaborative project of guys who meet every Tuesday (“Tiki Tuesday”) after work, to build the double canoe and assign “homework” for the following week. Scott’s (Model T sized) garage serves as the “canoe house”. Not exactly speedy progress, but they appear to enjoy themselves.

Thomas Nielsen (of Tsunamichaser) has been helping out with the build, and he brought a bamboo-skinned surfboard he’s made for Show and Tell. Coincidentally, Boat Bits blog told us about Greenlight Surfboard Supply last week who is into sustainable surfboard building materials, and their new Bamboo fiberglass.

Bamboo is the fastest-growing plant on Earth; it has been measured surging skyward as fast as 121 cm (48 in) in a 24-hour period, and can also reach maximal growth rate exceeding one meter (39 inches) per hour for short periods of time.

As anyone who has bamboo in their yard knows, it is only an Act of God that has kept the plant from completely taking over the world. It grows like a noxious weed, and that is half the reason it receives so much attention from sustainable materials scientists. The other half is because of the fiber’s remarkable engineering attributes, often called “green carbon fiber”.

Surfers are definitely the early adopters of the maritime world - taking the theoretical and making it practical. They embraced foam and fiberglass before everyone else, and it was also the watermen who first tried unballasted multihulls and canoe culture, with surfer Hobie Alter bringing the double canoe to the masses. It is already cooler to surf on bamboo than carbon fiber, can boats be far behind?

Wouldn’t it be cool to have a bamboo garden as your local “lumberyard” and “carbon fiber” factory? A superlative engineering material literally growing in your own backyard. No clear cuts, strip mines, or oil fields required. Don’t tell Exxon.

Tepuke

A pair of Santa Cruz Islands Tepuke sailing canoes. This canoe fascinates me, mostly because it flies against most of my notions of what constitutes a proper sailboat. The tiny sail area set from over-long spars, massive windage, submarining hull, etc. And yet I find it a beautiful and captivating craft. I even tried an updated version at Proafile. I strongly suspect that canoes like the Tepuke are the Pacific version of ancient Egyptian solar boats - in other words, their form is strongly influenced by a religious belief system. Perhaps the extreme crab claw sail represents something to the builders besides an aerodynamic power plant - something symbolic of an ancient religious concept, or totem? Like the upturned and highly stylized ends of Egyptian craft, or like the spires of medieval gothic churches.

To the Pacific Islanders, a boat was a living thing, a vessel imbued with spirit no less than a human being. I admittedly know little of their symbolism, but I do recognize a ‘church’ when I see one.

A Dick Newick Retrospective

Professional Boatbuilder has a nice feature on the life and career of Dick Newick, written by Steve Callahan. Besides interesting background (for example, Dick explored the canals of postwar Europe in a kayak long before such trips became popular), the article highlights the significant boats in his portfolio - a formidable list indeed. I didn’t know that it was Cheers, the 40’ OSTAR racing proa, that began his career in ocean racing multihulls.

Dick Newick was already regarded as an innovative designer, builder and sailor. But it took the 1968 Observer Singlehanded Transatlantic Race, or OSTAR - at the time the premier event for singlehanded sailors and their no-holds-barred boats - to telegraph Newick’s talent around the world.

The famous proa languished for years in the Exeter Maritime Museum until doctors Vincent and Nelie Besin brought her over to France for a complete restoration, where it has been made an official national monument. Interestingly, the Besins have commissioned a “new” Cheers from Newick - a 56’ (17m) proa for an around the world voyage. I can’t wait to see what 40 years of experience will bring!

‘Boat’ could explore Saturn moon

A daring proposal to try to put a “boat” down on a sea of Saturn’s moon Titan is about to be submitted to NASA. The scientific team behind the idea is targeting Ligeia Mare, a vast body of liquid methane sited in the high north of Saturn’s largest moon.

I know we sailors are a superstitious lot, but I hope they don’t name their ship the ‘Titanic’.

Aspen C-90 Set for January 2010 Launch

The Aspen C-90 is an innovative new 28’ “power proa“ cruiser, designed and built in the Pacific Northwest, and Schacht Marine was contracted for the industrial design. The small yacht embraces efficiency as it’s mantra, and promises to set a whole new benchmark in comfortable and economical cruising.

Rare Archival Drawings

I found an old college sketchbook from Architecture 101 buried in a box today. It was filled with site plans and sections but it included this drawing labeled ‘Hydrofoil Sailboat Cargo Vessel’. Also lots of sketches of beer coasters, cars and spaceships.

The 16x30 Sailing Canoe

John Summers has recreated a turn of the previous century decked sailing canoe in plywood stitch-and-glue construction. Yes!

The new 16-30 has met almost all the expectations I had for the project. The boat is only marginally more complicated to build than a stitch and glue kayak… Easily cartopped or pulled on the lightest of trailers, the boat is simple and robust, and can be rigged and underway in less than 15 minutes from the top of the car to the water.

The Allseas Eye

Fjord 40 Open

Fjord boats of Norway have reinvented themselves with some new models worth looking at. The Fjord 40 series are cut from the same cloth as a high style Med super yacht, which makes good sense because they were designed by the team of Patrick Banfield and Jim Wilshire (Allseas Design) - designers of megayacht tenders and the Wally Open. The Fjord project is actually quite down market for the pair - an ‘off the rack’ version of their more usual bespoke business.

Both yachts exhibit the trademark Allseas look: plumb bow, flat sheer, straight lines and square corners - an austerity of form combined with opulent materials that is impressive in the manner of a perfectly cut suit. It’s a difficult look to get right, and they do get it right.
