A little precisation; in 'The Little Cigarette' were Hal Sahlman and Harold Smith to set the world record of speed in the 1974 at 87.2mph.
The boat was one of the former 32' Cigarette that Balestrieri modified in 1971 cutting it to 31' with a deck in playwood.
Nordskog set his two records in 1975 and 1976 with his Cigarette 35' Powerboat Magazine Special at 88.7mph and 90.6mph.
The first official record breaking the 100mph barrier was set in 1980 by a British lady - Countess of Arran - at Windermere the famous lake of the speed records driving her Skean Dhu a 26'.5 Wright Marine powered with a couple of Mercury 225hp outboards!
At 102.5mph.
Skean Dhu wasn't a traditional cat but it was a trimaran boat.
What is an Advantage??
Post #34 pretty much covers it. It had 3 strikes. No wonder it was so fast..... Maybe doggy MPH?
the msv 44 built for mr carmati at that time had twin v12 bpms 1200 hp each at 4500 rpm connected to bpm z boxes 1.20 to1 overdrive,this turns the prop over 5000 rpm. these engines were hand built by OTAM S.P.A. They were dyno tested and installed by them. The exhaust were dry exiting thru the hatchs . ssm3 4 blade props. flippo sold this boat for me and attended the sea trials. sonny miller thanks for the questionAgreed...and we all can also agree that any of these boats when setup for an actual race (fuel load, weight forward, rough water props,etc) were considerably slower. the little Cigarette's and Skean Dhu were small special purpose boats designed for speed alone. Nordskog, whose boat was full sized, controlled the APBA at that time and had huge horsepower in his turbo charged engines. I am not saying that he cheated, rather that his boat fit the limit of the rules as written, and even he couldn't get near 100 mph. Most of the other Open boats had less power, and more dependability in the big seas races of the time.
I still would like to know precisely how the biggest boat on the race course at that time could also be the fastest?

Skean Dhu, a special purpose boat designed for speed alone? What makes you think that.It won it`s class on several occasions in Class IIID offshore racing,which was more than a trip round the bay (as per key west) and that was in a class with more than 4 boats as the U.S. like to do, and then call themselves World Champions,but that`s a thread in itself.OK it wasn`t OP1,but still a noteworthy achievement.
not sure flippo was still living in Italy and still a magnum dealer ,maybe 77-78. just before flippo and katrina bought magnum from don,they also moved into the palm bay club. I will check when I shipped this boat . maybe marco can call OTAM in porto fino and pull the Carimati file and also Burno Mentasti file, to check dates. sonny miller thanks I will post photo sWhat year was that done?
good question 1-1 ssm3 ran hot ,I lost port drive once in testing . I added grafite power to the gear oil to help cool them , and used a slow throttle up. also I kept raising the x measurement until I saw some drop in the boost. you are right we had to be careful.sonny millerSo was that the boat you referred to earlier in the quote below?
"yellow popeye msv 44 ran in pointpleasent ( fuego tutto) 100mph"
Also how did you get # 3 drives to survive with 1200 hp running through them?
Sorry to keep asking questions, but I am trying to understand the speeds attributed to the open boats racing in the U.S.

Did u buy it ?? NICE !!!!!!!!
1 more question,,,are banana boats and Advantage related ?

Unless I`ve missed something on this thread,I still can`t be clear on the builder of the 44ft Popeye.If MSV Inc built La Tortuga,where does Mands Marine fit in the Popeye build.Also if Miller was the designer,what role did Saccenti and Varese play,or was it an overlap of design ideas.
Could you give us more details on those engines? 1200hp engines in that time period, that would hold together, had to be very rare. I'm curious about the technology used to achieve those numbers.
Thanks for that Sonny.You mention 8ft wide hulls.For your interest,all Don Shead OP1 boats from Miss Enfield in 1969 to the CUV hulls were 8ft beam,i.e. stretched from 32ft to 41ft long over a period of 18yrs.
