THE ULTIMATE DELTA CONIC BOAT...

aaronbocknek · Post by **aaronbocknek** » Mon Oct 08, 2012 6:41 am

after reading the information supplied by rws, i got curious about harry schoell's infinity yacht corporation. found this 56' infinity on yachtworld.
delta conic hull and surface drives. when you look at the interior, you can see the typical rounded interior furnishings and bulkheads. the exterior is wicked nice too..... so the 'trojan international' really did grow up. just thought i'd pass it on as there are many on here, including myself, who are curious about the delta conic concept.
enjoy.

I find it interesting that we have essentially 3 interpretations of what could have been the next generation of the International, and with Trojan looking to update the International series, theses 3 designs could have been in the running:

1. Harry Schoell's design as seen in the Infinity Yachts. A very sleek express with a high horsepower surface drive,

2. Fulvio de Simoni's design, seen in the Carver Trojan 440, and also Fulvio's solely designed Pershing Yachts. Yet another sleek express cruiser with high horsepower surface drives.

3. And finally the design that Trojan was trying to create prior to their demise, which was a hybrid of sorts, that entailed the top design created by Fulvio De Simoni and the hull created by Bertram's own Lee Dana, which you can see with the 10.8 Meter Express.

One of the differences you can see between Trojan and both Schoell and De Simoni is that Trojan was not planning on abandoning the Convertible, as they were already designing a new 10.8 Meter Convertible on the same platform as the 10.8 M Express.

I am posting pictures of 4 different boats that could have been the new International series. To make it consistent, I posted boats made during the same decade, all of which were produced between 1991 and 1998. It's interesting to see the differences and similiarities of these boats.

The Harry Schoell 1994 Infinity 58

The Fulvio De Simoni 1994 Pershing 60

The Carver Trojan 1998 Trojan 440, designed exclusively by Fulvio De Simoni and produced by Carver

The 1991 Trojan International 10.8 Meter Express, with Topside designed by Fulvio De Simoni, hull designed by Bertram VP of engineering Lee Dana, and produced by Trojan Yacht Company

Hey Aaron,

I've had this boat a couple of years now, and upgraded the tabs from 18x9 to 24 x12 with drop fins , which helped tremendously with keeping to bow down. I've been out a few times on Lake Ontario with 4 to 5s. Lake Ontario can put out some nasty weather and waves. At rest, the boat will rock and roll more than the delta conic in 2 and 3 foot waves. On plane, I traveled approximately 60 miles in 3 and 4 footers with an occasional 5 footer. The first time I came off a 5 footer and saw the water disappear below me, I braced for impact, and was pleasantly surprised with a very soft landing. The boat does not pound at all, and is extremely stable on plane. And the faster she goes, the better she rides, which is part of my issue. She rides the best at about 24 mph, which is screaming with my Crusaders. So we cruise at 18 to 20. She definately would perform better with more torque, as she loses rpm's when she pushes that bow through a 4 or 5 footer. She can be a little wet as she has much smaller chines than the delta conic. Following seas can pull the stern a little, but nothing crazy. I would feel pretty confident in some bigger seas, but with a set of lighweight diesels would make this into a big water machine.

thanks for the response todd. much appreciated. i'm not sure why i'm so bloody curious about the internationals now, but rws thinks i'm probably destined in a few years to maybe own one..... who knows. for now, i'm ecstatic w/ my tri cabin. IF i did consider a meter boat, i'd most likely get the 10.8 sedan. i need windows to see out of.

i loved how you said, 'brace for impact'. sounds like my line of work when we prep a cabin for an emergency. i appreciate your kindness,as well as rws, with feeding my knowledge base on this. i saw a meter boat at the boat yard near me today that i did not recognize. check out the latest thread.
again, thanks.

perhaps there is a pair of Yanmars or Cummins in your future?

then you would have THE ULTIMATE BOAT!

Of course, you would then have to keep her for at least 10 seasons or so.

Not a bad proposition, is it?

Actually a little less than a week. Oct. 14th. The big 42. Happy Birthday by the way. Maybe a nice 10.8 Meter Convertible is waiting for you.

Hey Captain Aaron, wouldn't you think a couple of Warp Drives would be superior to Diesel?
