You would sure need a very large lake for this one

In a show I did last year we have footage of this thing (or at least the same design) actually flying. I think the footage was from Florida as I recall it being near those water skiing babes from (what is it?) Coral Gardens.

Bensen B-8M Gyro-Boat.
Developed by gyrocopter designer and manufacturer Igor Bensen as a variant of his B-8 Gyro-Glider in 1956, the Gyro-Boat adapted the basic free-turning, two-bladed rotor system, so that it could be mounted on a standard dinghy. A prototype was first flown on 25th April 1956 and was followed by the production model in July 1956. To launch the Gyro-Boat, it was towed with an ordinary water-ski rope behind a speedboat capable of at least 50km/h(30mph). It usually became airborne at about 15km/h(25mph) after a short run of about 92m (300ft) across the water and cruised at a rotor speed of 350rpm. Height reached usually depended on the length of tow cable, recommended as 46m(150ft), although a longer rope could be used as the pilot gained proficiency and confidence. Landing speed, with a slack or disengaged tow cable was about 13km/h (8mph). The Gyro-Boat was supplied to customers as a complete boat with the rotor system for £200,
or the rotor dynamics could be purchased separately for £169. This example was assembled and test flown by the General Developments Company of Glasgow and purchased new by a Mr. McGill in the 1960s. It was test flown once on a Scottish loch with his son Gordon as pilot, but both were then grounded immediately by the family for safety reasons! In the late 1990s it was restored by Gordon McGill and donated to the Brooklands Museum, before being transferred to The Helicopter Museum in October 2003

The Gyro behind it Is G-BAPS a Campbell Cougar. I think it was designed by Peter Lovegrove.

The American prototype used a standard aluminum utility boat rather like this:
