I did and posted verifiable info from the manufacturers and regular tester mag results .Your googling could use some refinement, PF.
They clocked a max speed of 50.2 kts (yes, FIFTY, not a typo) on their last 78 - which btw is a MUCH bigger boat than the Itama 75.
And over the Pond, the wave-bashing capabilities of their hulls are as legendary as Magnum's, just to name an Itama-like type of boat.
All pretty academic anyhow, since anyone interested in a superfast freight train whose range is sufficient for crossing to Bermuda would laugh at the idea of any open boat meant for day trips to Capri - or Nassau, for that matter.
Your info is from a one off .The regular ones are a lot slower ....maybe correctly or different propping ? .
It's Michael Rybovich and Son's new Hull # 5 Persistence...78' Sportfish. Twin MTU 16V 2000 M96L's at 2600hp,each. Burning 250 GPH wide open (2450 RPM)...160 GPH (1850 RPM) = 36 kts
additionally this test was reduced to a real 47 knots gps over the seabed after taking the gulf stream water current into consideration.
For those reading the cooking / std R 78 came with similar Hp 1800 ish CAT s to the Itama 75 s 1800 Hp ish MTU ,s .......so more or less the same HP out of the box .
Interesting what a “ one off “ Itama 75 with shoe horned MTU V 16 2600 Hp ( like the R 78 ) would do ........to keep the comparison as scientifically accurate and thus meaningful.
Any how agree academic in the real world . Not sure where “ open “ plays a part as the Nortec 80 is a across the pond type of open Miami = Nassau boat that can easily 60 knots .
back in the Med ,the sea / waves as you should know regularly in the summer are big enough to warrant any serious Med boater to wish his boat was more capable tacking the rough stuff .That includes professional boat skippers running day trippers around your beautiful country .
There’s a reason why professionals gravitate towards Itama .......wonder why ?
Remember MapishM.........keep away from Frog research
