RE: first FE hydro
Just how badly did you mess up the other hull? I repaired one that even I didn't think that I could save. My wife hit a retrieve boat WOT avoiding an idiot at a race. Yes, the retrieve boat was docked at the time but anyway I found it easier to fix after I'd gotten some tips on fixing it. ABS hulls are some of the easiest ones to mend.
Mine was a DPI 3.5 OB tunnel that has the fronts of the sponsons bent upward from the impact.
