I'm sorry , not the Skater designer, It's the guy that designs allot of UIM Class 1 hulls . I just read the article but seemed to have forgotten the name.
As far as I know there is only the 32 Dominator hull.
had a light layup F1 hull that went 79 with a single HP500
and the standard full cabin model runs mid eighties with twin 500's sounds right to me
