A comment from the Michigan Wheel Site: "Slip Slip is the difference between actual and theoretical travel of the propeller blades through...
I used straight pitch instead of a measure pitch taken at the 0.7R as I don't have those details handy for Veem's, Frances Helices and others prop...
Yeah, I saw that too, the magazine 54 Donzi test boat theoretical zero slip speed was all the way up to 44 knots if it in fact had 45" of pitch....
I think you are in good shape, the Veem propellers are a not so secret weapon in getting to your speed targets. Makes me want to stick with my...
Not too concerned about 90 footers. I found a 1995 Boating test on a Donzi 54 and the numbers look pretty good: [ATTACH] They even hit my...
Length doesn’t matter. Stuffing high horsepower with the resulting high fuel consumption into any design does not necessarily make it an...
The reference 55 Hatt’s were built from 1980 to 1989 while the 54 Donzi’s were available from 1989 to 1997 and represented a next generation...
The older gen 55 Hatt has a beam of 17’-6” beam with a 4’-10” draft including a speed sucking keel. The 54 Donzi has a beam of 17’-4” with a...
At 76,000 lbs. you may be pushing my numbers a bit, so I would expect a drop of up to 1 knot on WOT / Cruise. For an additional reference, a 58...
I was using 68 - 72,000 lbs. plus the data from the Hatt 55 repower. I would expect your Donzi to have a faster speed potential than the Hatt, so...
I took a quick peak at the numbers and you should see 32 knots WOT and a 25 - 26 knot cruise, 1950 - 2100 rpm as long as the weight does not grow....

You mean like Jimmy Buffet's 42 Freeman: [IMG] https://www.buffettnews.com/2019/08/10/28434/ According to CaptJ, there are no Freeman's...
The 43 Tiara LS is less CC and more an outboard powered Express, the helm is way far forward and is a completely different type of design. The...
It looks good for moving a big group of people around and the broken sheer is distinctive and can’t be confused with any other brand other than...
Crowded playing field, looks less fishy more sporty.....
I would say that those speeds for the 55 Hatt look to be on the optimistic side or at the very least, light load speeds, but knew you would be...
Nice looking machinery. I found a 55 Hatt SF that repowered with C18's, thought you might like a peek:...
Stainless steel bolts with a bronze Rudder Bearing Plate?? Underwater??
Glad to hear they are taking care of you, have a coworker who has had both hips and both knees done and he has great mobility, playing golf and...
