THis design is great but it happens to have the exact problem that Cambells one had in 1966, after 275mph it is inherently unstable....feel free to try and sort it out!! Let me know how you get on. 275mph was about 55-60% power.

After a quick test one thing I can tell you is that the floats on the outriggers sit higher than the main hull. At low speed this is fine because they're still in the water. But once you get up to speed and boat begins to rise out of the water they become useless. I had the same problem. Use the nudge function to lower the floats until they're even with or lower than the main hull.
Take a look at mine and compare notes. My boat is stable past 300mph.Try using structural wings instead of fuselage pieces for your struts. As they are now they're probably creating too much drag. https://www.simpleplanes.com/a/6fxxHd/Bluebird-K7-Jet-boat
The stabilizers to small if it was bigger it would be really god
