What's the speed difference between the stepped and non-stepped hulls? Are these good rough water boats?

FredZ - 1.5/just about 6 grand on the revs!


Stepped hull 27's are significantly faster on average than straight bottom hulls if all other variables are the same. Not sure about exact numbers. I can tell you 650 hp in an older straight bottom was showing aroung 80 mph. I dont think speed numbers would be linear though. As the step 27 increases speed, it seems to need less hp to gain more mph; shes very efficient aero and hydro-dynamically.

What drive are you using? any problems with it?

i got almost the same setup that is going in a 27 in the future. XR/sportmaster 1.35 and just over 800hp.
Thinking the drive is the weak spot?

You'll probably be on borrowed time with the xr. I run an imco scx/sc combo. I replaced the lower gear set at about 70 hours.

Not that you'd be running big numbers in rough water with a 27' boat, but I presume these are good in the rough? What is the hull based on? I presume it's a stretched 24x7?

Not sure what you consider fast for a 27' in the rough but I think you would be surprised. Very capable hull in the rough.

The hull is from Bill Farmer's 27 Excalibur. Wellcraft bought the molds in 84-85 and made them for a few years then Activator bought them. Years later the steps were added.

Well, presumably not 106 mph! Good to know. One of these might be a good upgrade from our 24 SB in a few years.
