Anyone care to hazard a guess on fuel consumption?

Here's a performance curve from mine before I did the retrofit.
Mine is an express cruiser as compared to Scott's which is a mid cabin model.
They have differentprop sizes and transmission ratios which may account forthe difference in economy.
Also consider that you are moving a vessel of considerable more girth than a standard 33' boat with a beam of 10 or 11'
These numbers were achieved after removing the exhaust diverters, correcting the timing advance curve and replacing the fuel metering rods in one carburetor which had been consuming 5 GPH more than the other carb.
1982 Trojan International Express Cruiser
10 meter (33') with a beam of 13'
Harry Schoel Delta-Conic Hull design
454 Crusader 330/350 HP original carbureted engines
published weight 12,500 lbs dry - questionable weight for stripped down vessel, actual dry may be 14,000 +,-
test run 2/10/04
Tests done with digital tach/synchronizer, GPS and flowscan
After replacing the secondaries metering rod brackets to original
corrected carburetor metering rods
Props 4 blade 18 x 19
stock 9x24 trim tabs replaced with 12x24 tabs with 3" drop fins
2 Adults
sea conditions very smooth
carrying 40 gal water and 143 gal fuel

REgarding the above data, I don't have flowscans on the diesels so it's difficult to get a snapshot of fuel consumption at any given RPM. A run to Key WEst with 8 adults, full tanks and all of thier luggage yielded 1.4 NMPG at 22-23 knots. Pretty incredible.
I believe we're cruising at about 1.6 or so at 21 kts which seems to be the most economical cruising speed to cover territory without pushing her engines. She tops out at 27.3 kts WOT 4000 RPM.
Once on top of the water this hull has an incredible ability to remain on plane at slower speeds so there's no telling what the effeciencies are between 13-22 kts with the diesels.
At displacement speeds it's anybody's guess.
You absolutely will not be dissapointed with the design, engineering or construction of this vessel.

Crossed one more hurdle this weekend -- got the guy that has my desired slip to agree to swap with me. This will put me on the top of the "T" (the outside slip at the end of the dock). Positives are that I'll have no issues docking and departing, it's next to my buddy's boat, and it's a much better view of the water. Negative is it will ride the dock as the prevailing winds and boat wakes will be on the outboard side and transom. Will need to set up the fenders very carefully.
Also talked to marina owner who said no problem. Now need to 1) convince wife to move forward (she's generally on board but wants to look at smaller boats - yuck!) and 2) start the purchase process (offer, hull survey, engine survey, fluid analysis, sea trial, etc.). Just posted my current boat and am seeing interest already. Have slept on board last few nights and OH MAN does it seem SMALL all of a sudden.

This is so fun !!! Really !!!

Update: We've decided to decline this boat and go a different direction. Am now in final stages of purchasing a 1989 Sea Ray 300 Sundancer, and will look at used jet boats next year. That said, here are some impressions of the Trojan from our second visit:
1. Boat was immaculate -- new -- on the outside. All gelcoat, striping, details, brightwork, teak, etc. was absolutely perfect.
2. Layout was the main problem... main stateroom was very claustrophobic and small. Felt too closed in with only the small doorway and one hatch. Sleeping surface was actually smaller than the angled berth on our old 25' boat. Deal breaker for the wife.
3. Layout continued... the cockpit was fine & dandy, and would have been great for us. Same with the main salon. Had room for a loveseat and bar-stool type helm seat plus a recliner for me and room for a TV to watch the golf on Sundays. Oh, well... that would've been nice. Flybridge was very cramped. Didn't notice that on first trip but it was so small it was nearly useless.
4. Mechanical condition was excellent. All ships main systems were near perfect. Air conditioning was a bit smelly but I could've fixed that up easily.
5. Odds and ends were mixed. Well, it is a 1982 boat after all... multiple switches were inoperative (specifically the touch-buttons common on older Trojans, they felt worn out). Couldn't get the microwave to fire up, nor could we get some of the plugs to work in the cabin. Overall interior fit & finish was holding up amazingly well, and even the fabrics, vinyl, and carpet were in great shape.
I would encourage anyone interested in a boat like this -- or this boat specifically -- to give it a very hard look. For the right buyer it would be a STEAL. He will likely take mid-$20's by this autumn if not sold.
I didn't get far enough to have it surveyed or have the motors inspected by my mechanic, and I would strongly encourage anyone who is serious to do both. Boat is too old to take a chance, but it sure looked good to me.
Best regards,
-Doug.

Doug,
It's a shame you and your wife didn'thave the opportunity to experience the ride qualities of the Trojan's hull design. There is an interesting chapter in David Pascoe's book MID SIZED POWER BOATS where he discusses hull design at length and shows photographs of several different mid sized boats.
Having a layout that will work for you own particular taste is also important and the Sundancer is a nice boat.
I myself prefer the express cruiser layout vs the convertible. Generally speaking much less time is spent IN the boat vs ON the boat. With the express cruiser layout there's enoughroom for everyone to be ON the boat together.
If the opportunity ever presents itself, take a ride on a Trojan International series to experience the ride before you buy your NEXT boat!
Good luck with your new Sea Ray, get her out and enjoy our favorite pasttime as much as you can.

Just to close out this thread... we did end up with the 1989 SR300DA. Spent the weekend cleaning and getting familiar, and we're very happy so far. Absolutely killed the seller on price (I think) and couldn't pass it up.
Thanks for all the input on this topic -- really appreciate this forum !!

No, quite a bit different. Our side exhaust is a single, small port about 5 inches above the waterline aimed straight down. It's only engaged under 900 rpm or so, past that the bottom exhaust switches in. If I remember, I'll get some shots of our side exhaust this weekend.
I just noticed the remark on the forward berth. I know you passed on the boat but the forward berths on the 10 meters slide out and two filler cushins are added to increase the length. It ends up being a pretty large berth. I think they used the sliding feature to allow some standing room inside the door once the bed is slid bak in. O think on the 11 meters and up they do not need the sliding berth.
It is a closed staeroom instead of being open to the rest of the boat so it won't be the preferred choice for some.

Boy, I will definitely second this. The ride of our Trojan is so superior to most everything else in this size range that there's hardly any comparison. Stability in rough water, crossing wakes, etc is just plain amazing. It's the only boat I've ever been around where we can leave things sitting on a flat surface without worrying about them being tossed off in rough conditions. Yes, it is that stable. Of course at ten tons, the weight has a lot to do with the stability too.
As for interior space, the Tri-Cabin F36 has an amazing amount of room. The master berth is a full walkaround bed on three sides, two full heads (master has a tub)etc, etc. Everyone that takes a tour of our boat is amazed by the interior space. It's not as "sexy" looking as an express cruiser, but the livability factor is tremendously higher.
Here's a shot of our boat decorated up for the 4th:

Regarding the Trojan 10 Meter International, the forward cabin is different on the mid cabin vs the express cruiser.
As far as the hull design is concerned, numerous nautical magazine articles were written in the day. I have a collection posted here along with additional info on the International series.
