I have an 85 stiletto 23. I'd be shocked if it actually weighed 850 pds. I think that is really optimistic. Myboat is kevlar/nomex and though I have never weighed the boat,I have moved the hulls around quite a bit. I have also talked to Peter about it quite a bit, I think the 23 is realistically closer to 1000 pds. My instinct says "bad idea", but i'm not an engineer. The loads on my boat are pretty extreme when shes powered up. certainly a lot more than on a sc 20. Dont forget, the 23 is almost 4' wider than the SC 20. So you'd be hanging 200 plus more pounds on a 4 foot longer lever when you are flying a hull, i'd be very worried.
