92 marstrom 55mm
87 reg white 110mm
Hobie tiger 90mm
Nacra F18 95mm
Blade F18 Home build 20mm
Lets face the music guys the, Marstrom 1992 Tornado showed no less than 2.5 times the flexing this home build boat did ! Sure old boats flex more but they don't deteriorated that much. Besides everybody claims how good Tornado's keep their stiffness over many years of sailing.
Now either Marstrom 1992 boats are [censored] (but still significant stiffer than much newer Tigers and Nacra F18's by a factor of almost 2) or the Blade boys did something very right.
I think you have to be very careful comparing the stiffness of different boats. Comparing an F18 to a T such as above has to many variables. ie width, length and weight not to mention age. I know that Marcus has re beamed his Marstrom. Was this done before or after the test. This is a 12 year old boat that was in need of some TLC before Marcus bought it. The front beam was also riddled with holes from moving fittings around. If you wanted to test the stifness of the Marstrom, it would have been allot better to use a new or near new platform.
Also the Reg White used was a 17 year old boat with the small beams. Hardly a fair comparison with a brand new F18.
This test was only ment for a rough personal guide for the guys and should be taken as that.
