Building a Texas sled 18 (inverted V) need advice on improving turning ability

Hi, I'm currently building a modified version of the Boat Builders Central Texas Sled (TX18). I've increased all dimensions by 10%, so now have a 20ft boat (designer has approved this). The hull is heavier than designed due to more glass layers and the consol design. I'm planning to run a 140HP Suzuki (at our altitude it's closer to 115hp I'm told).

As the hull is very flat towards the stern I am beginning to worry about the possibility of blowouts if I need to make an emergency turn at speed.

I am looking for advice and if this is likely on an inverted V, and if so what might I do to modify the hull to reduce the chances of this happening. I was considering a pair, or more, of strakes, but am unsure the best approach to this. Length, positioning etc.

Any help and advice would be greatly appreciated.

 

I suggest you build and try it before modifying anything. Explore the performance and limitations of your boat before fixing a problem that probably doesn't exist. Aggressive steering at high speed is dangerous in every vehicle there is.

 

DC brings a good point. If you turn sharp enough to need strakes for tracking; you are probably driving poorly.

 

Certainly worthwhile for you to read the sea sled information thread.

 

Probably best to call Boat Builders Central and find out if they have had any issues.

 

He got crickets there. I told him there was a Seasled cult here.
