High speed river cat.

[montero]

Yes sir.

 

[montero]

Because I feel I could go much faster with such an engine on the right boat.

yes I know that 3.3 are not very good.

What I'd like to ask about is the safety factor of high-speed design. Even competition boats have minimum allowable weights. I want this boat to be incredibly light, but I don't want to kill myself or anyone else.

It's a very vague question, so you'll hardly find a correct answer.

In speed competitions, it doesn't seem logical to limit the minimum weight. On the contrary, the designer should aim for the minimum weight.
You will have to design the entire hull to withstand impacts against the water—I mean impacts, not hydrostatic pressure, slamming, etc.—or impacts with rocks or floating objects.

There are specific regulations for each class. Among them, there's a minimum weight. You can't go below that. This is for safety reasons.

I can't discuss that (minimum weight) with you; I don't know the rules you're referring to.

 

[montero]

e.g. F2 minimum weight is 513kg . Driver+hull+engine+fuel.

 

[montero]

Not sure about fuel. Maybe minimal level.

You're right, some rules do specify a minimum weight. I was mistaken, my apologies.
The F2 minimum, according to AI, is around 780 kg.

 

[montero]

It's 550 kg including pilot . Don't know what amount of fuel . Probably minimum.
