Ok i know, not in the same price range and 6 feet difference
Besides that, it seems like a bigger nortech with 700 hp seems to run in the 140-160 mph range
While the smaller chriscat with similar power runs in the 100-110 mph range
Why is that? Is a 36 nortech lighter than a 30 chriscat? Or is it because the tunnel is more efficient on the nortech? Even if the 30 would be heavier, i cant imagine a 36 nortech having a rougher ride than a chriscat 30?
Any thoughts about that from people who knows?

For starters, NO Nortech will run in the 140-160 with 700's. For that matter barely any Nortech run close to 160 besides " Loose Canynon" when Joe from Sarasota build it in 2005 and that one exceeded 160 when it wasn't broken.

36NT/700s more like 130 downhill with a tailwind

there was a mti speedracer with 525 that ran 115 mph if my memory serves me well... right? wasn it a 40 feet?

so 20-30 mph faster in a 6 foot bigger boat with similar power... again my question is how? or why?

exactly what I thought lol.

Weight, hull design, steps, and etc.

That boat ran just over 100mph at a shootout on the Mississippi river a few years ago, its also a stripped down race boat with no cabin so its got to be pretty light for what it is.

The Speedracer boat with 525's...
