A book on Ditchburn boats states that: “Pioneer British designer and builder SE (Sam) Saunders of Crowe England had built several stepped-hull vessels before the first world war”

From A Brief History of the Gold Cup - Hydroplane and Raceboat Museum (ning.com), “the first hydroplane hull to win the Gold Cup was MIT II in 1911 with J.H. Hayden at the wheel. The hydroplanes with their underside “steps” and their ability to plane over the surface of the water spelled the end of the displacement era.” From 1922-1928 stepped hulls were not allowed in Gold Cup racing.

The Ditchburn Viking, introduced in 1927 was the first Canadian boat with a stepped hull. It was a 27’ long with a 6’6” beam and a weight of around 5000 lb, depending upon the engine selected. These boats went over 40 mph.

Stepped hulls were re-introduced in Canada by J Craft around 1990-1991. They built a 17’ shallow V with a stepped bottom.

I don’t know when the first US production stepped hull was introduced. Hustler brought out their first stepped hull in 1993. Hustler Powerboats- History (hustlerspeedboats.net). Fountain’s stepped hulls were introduced in the August 1994 issue of Powerboat Magazine.

Saunders/Saunders-Roe - internationally renowned builders of some of the fastest boats of their time, as well as flying boats. It is the town of Cowes on the Isle of Wight located South of Portsmouth. Just been there to watch the Cowes Torquay Cowes International Offshore Powerboat Race (27 August), from a spectator boat.
Michael Levi - son of famous offshore racer/designer Sonny Levi was chairman of the Race Committee.
It is beneficial when your daughter (and her family) live in Portsmouth. Costs of accommodation, food and drink in the UK will make you cry, and it is getting worse.
So much for Brexit, instigated by certain Conservatives to lay their hands on the tiller of governmental power.

Nice 3.5 cc RC tunnel. OS XM ver. 2 air cooled nitro engine. Aftermarket cowl, manufacturer escapes me - although I own one......can't identify the hull, looks European. A new record was recently set for 3.5 cc ob tunnel in IMPBA Sport tunnel. Internal mods allowed, outside absolutely bone stock- carb, exhaust, etc. 68 & some change real mph. That's using less than 1/4 cubic inch (.21)!

Tryed it that way almost impossible to not break a ring.
Best way is to put the piston and rods in first one by one .
Set the crank and bring them up one by one.
