Sampson Boat Co.
Saved by uncleflo on February 12th, 2022.
Right now, I’m on a mission to rebuild a 111-year old (as of 2021) English sailing yacht called Tally Ho. Designed by Albert Strange in 1909, she is a well-known and important historic vessel – but after many adventures she was left in a remote port in Oregon to rot for decades, despite some valiant attempts to rescue her. I bought her and moved her to the Olympic Peninsular earlier this year, and am now starting to rebuild her from the keel up. Eventually I hope to sail her back to the UK. If you are interesting in supporting this mission you can do so here. I started the Sampson Boat Co in 2013 as a platform through which to work as a self-employed Boatbuilder. Since then I have also started writing about my sailing and boatbuilding projects, so this website has become a kind of blog, as well as a display of my work.

Spirit-Of-Tradition Registry: Swede 55 -- A Knud Reimers Design
Saved by uncleflo on February 12th, 2022.
Surprisingly undocumented for a design this important — most searches for the “Vortex 55” lead to a hand mixer — these Knud Reimers boats were among the first group to sound the starting gun for the modern Spirit-of-Tradition narrative. Drawn in 1975, the Swede 55 was all about Reimers adapting a square-meter rule, popular for that time, to a mass-produced, fiberglass 53-foot day-sailer. Something like 35 were built between about 1975 and 1985, with names like Tiana, and Rosina. What matters today is, if you look carefully at the original design to the right, is how Reimers lays out most of the arguments of the Spirit-of-Tradition continuum: A traditional looking overhanging bow and stern, a slender hull matched to a modern keel and spade rudder — all with the most current rig and sails of the time. But what makes the design indispensable is how, back in the late 1980s Steve White, owner of Maine’s Brooklin Boat Yard, decided the Swede 55 would speak to his interests more if built out of composite wood construction. White had Reimers make a few tweaks for the build; and after a reported 7,000 man-hours of production (whoa!), a cold-molded wood layup of this modern-classic splashed into Maine’s Jericho Bay in 1990, christened as Vortex. We’ll save the ugly nitty-gritty of finessing the Spirit-of-Tradition principles into the constrained square-meter rule at the heart of this boat for another day. But still, we’ve sailed Vortex a lot. We’re in a few of these photos and videos, if you look carefully. And we can honestly report, of all the Spirit-of-Tradition boats we’ve sailed and designed, the Swede 55 is as pure a modern-classic as any vessel afloat. The Swede 55 may be from another era. But she still matters today.

Boat Lightning Attenuation Onboard
Saved by uncleflo on May 11th, 2021.
According to published reports, in the US out of the annual average of about 100 deaths due to lightning, approximately 13 are aboard boats. Suffice it to say that if lightning is a hazard where your boat will be used, a plan should be developed to deal with the possibility of a direct strike. In the Pacific Northwest lightning is relatively rare. In Florida, some areas annually have more than fifty strikes per square mile..! According to the well known lightning researcher Ewen Thompson, lightning can develop on the order of one hundred million volts, peak currents of tens of thousands of amps, and generate temperatures of some fifty five thousand degrees. Fortunately, it lasts only a fraction of a second, but within that time it can be deadly and / or very destructive. A lightning strike involves an extremely rapid change in an electric current, generating a momentary but extremely powerful magnetic field. This electro-magnetic pulse (EMP) will readily induce currents in adjacent wiring. Currents induced in wires by the EMP from a lightning strike may do some very weird things, such as fry every piece of electronics aboard. A strike nearby or on another boat can fry the electronics aboard your boat without even requiring an electrical connection or direct strike.

Arvel Gentry | North Sails
Saved by uncleflo on April 10th, 2021.
In the first edition of the Art and Science of Sails, written by Tom Whidden, president of North Sails Group, LLC, and Michael Levitt, and published by St. Martin’s Press, the authors used Arvel Gentry’s now famous Bathtub Experiment to demonstrate the existence of Circulation, or a second force, that operates around an airfoil, like a sail, wing, or keel etc. Big picture: it’s the combined effort of these two forces that makes the wind speed up on the leeward side — and thus show low pressure — and slow down on the windward side of a sail — high pressure. Gentry was the Boeing engineer who first taught sailors aerodynamics. These diagrams first appeared in Gentry’s Sail magazine articles. In the Revised Edition, the authors used computer testing to show where the wind speeds up around a sail plan and where it slows down. And why and by how much? Nevertheless, Gentry’s experiment is the standard — still popular on the web — and it was left it out of the Revised Edition with trepidation, but we linked in the book to this web page.

Swan 120 - Nautor's Swan
Saved by uncleflo on April 10th, 2021.
The history of Swan Maxis begins early on, a few years after the establishment of Nautor. An expert client asked for a 17 m Sparkman & Stephens. It was the year 1970 and the magnificent Swan 55 took shape. At that time, it was one of the largest yachts in the world to be produced in series and in fibreglass. Sixteen were built, in both yawl and sloop versions. “The new Swan 120 Superyacht encompasses Nautor´s philosophy and DNA on its largest expression. Her sailing performance is exhilarating, thanks to the modern canoe body of the hull and the sail plan matched by an efficient twin rudder lateral plan which includes various keel options. A pioneering clean and efficient push button control deck arrangement offering ample access to the sea and sun bathing it is another of the key ingredients. All in all the 120 it is a very attractive proposition, created by a team of experts, and built according to Nautor best practice.”

F-Class « YachtWorld UK
Saved by uncleflo on February 23rd, 2019.
A well-designed sailing yacht is a thing of pure beauty, here are just 10 of the world’s finest… in my eyes at least! Velsheda
When she was launched in 1933, the J-Class yacht Velsheda represented the cutting edge of technology and sophistication and won races against all the great yachts of her day. However, she only was only used for three seasons and after World War 2 it looked as though none of these great yachts would ever sail again. King George V’s Britannia had already been scuttled south of the Isle of Wight, and Velsheda became a houseboat, firmly embedded into the River Hamble Mud for almost 50 years. In the 1970s she was saved from being cut up for scrap after being bought by a group of enthusiasts led by Bembridge bank manager Royce Pook. She then became the first of the class to be restored – in near original specification – thanks to Yorkshire scrap metal merchant Terry Brabant who bought her in 1984. Further refits after Brabant’s ownership saw her refurbished into the spectacular luxury yacht we see today.
