Could someone give me a rough idea ...how many GPH (just looking for a guesstamate) at cruise speed the following vessel would burn. Thanks ....

Builder: Trojan Designer: Trojan

Model - 1979 F-32

Dimensions

LOA: 32' Beam: 13' Displacement: 12000
Draft: 2'6" Bridge Clearance: 12'6"

Engines

Engine(s): Fords Engine(s) HP: 225 Engine Model: 351
Hours: 601 Cruising Speed: 18-19 knots Max Speed: 25 knots

Tankage

Fuel: 220 Water: 40 Holding: 20
 
I'm thinking less Greg...a boat that size and age should be in the lower 20's...say 22 to 24
 
Don't know gph but do know it has a flat aft and not a deep v which will help reduce gph. 12,000 pounds is pretty light too.
 
I had an F36 and I was at 24-26gph. You should figure in the low 20s.

If you google trojanboats, you will get the owners website and there are alot of F32 owners there.
 
We have a 1978 F-32 with Mercruiser 225's. At anything under 2800 rpm's, we get 8-10 gph. Over 2800, the 4-barrels kick in, and consumption goes to 15 gph. We have never burned more than that.

I appreciate all the help. Thanks and take care
 
I have a 78 Trojan F32 with Mercruiser 228's in it and we get 7.5 gph at 2800 rpm per side for a speed of 16 kts at 3000 rpm we get a speed of 18 kts and burn 11 gph

Hope that helps
 
I too have an F32 that used to have 225hp gas engines with flowscans. At the time, my boat had 1:1.5 gears and 16x16 3 blade props. Mine is a 1974 and like most F-32's, weighed quite a bit more than the published dry/shipping weight (closer to 16,000 lbs. loaded). My actual (as measured fuel) burn was between 11-13 GPH PER ENGINE at 17-19 knots. So your looking at 22-26 GPH total depending on sea state.

wow! If LSP doens't mind the hijack, I'd love to hear/see more about those modifications.
 
I've heard that the air intake had been problematic - it looks that like that's been redesigned too. (didn't Trojan move it above the deck on later models?)
 
I'll probably re-install the rails but the shot above was taken right after I painted the topsides this season. She's 33 years old but a lot of her is much younger. The only real apparent mods are the new vents, the window treatment and the hardtop. I coverted her to diesels in '03 which really helped with fuel bills and redid the interior in '06. I have few before and after shots below- sorry to be self indulgent.

Really like what you've done with the boat, J. A modernized F-32 is a great looking boat. Mind sharing the upgrade $$ with us?
 
beautiful! I grew up on Trojan Yachts. 30's & 36's. They're great boats that have always drawn me in. What's the performance like now?

How did you re-work the vents? I assume you had to avoid the orig. water-sucking design and provide enough supply for heavy-breathing diesels at the same time?

self-indulgent? heck - you're teasing us here!

Have you re-worked the helm?
 
You guys are too nice.

Bruce - I'm afraid to share cost's as it WILL show me to be a rather foolish man... especially in this boat market, (and that's with free labor). I did it becuase I enjoyed doing it. To give you an idea though, I have more into it (even forgetting the puchase price of the boat), than I probably could get for her today...Oh well, no one ever got into boating thinking it was a financially sound decision.

SLW- the original vents sucked - literally. They would scoop water and spray into the boat and, with all those little louvers, they were impossible to keep clean. I made the new ones but didn't get to splash it this year so next season will tell. Performance after the diesels has been nice - especially with fuel prices after '03. I no longer have flow scans because of the diesels return lines but, average consumption is way down... almost cut in half (around 8 GPH total). My best guess from the engines power/ fuel curves puts consumption (per engine) at 9 GPH at WOT 23/24 knots, 7 GPH at 20/21 knots (this is my new conservative cruise speed at 10% below rated WOT). If I was to compare to my old cruise speed of around 18 knots, I went from burning around 22 GPH total of gasline to about 12 gph total of diesel. It's not without draw backs though - soot & smell can be a problem for the misses.

As far as the helms, I changed all the guages, controls, cables etc.. but the general layout looks original... not much innovation there. One thing I'm proud of and it doesn't show up real well in the pics is a custom cabinet I made for a tiny space right besides the new midsize fridge/freezer. That little thing is deep and on ball bearing slides. It holds over 2 cases of cans for restocking the fridge... little things amuse little minds.

LSP - I do want to share this with you if your considering buying one. Even though I own one and like it, I have no illusions about Trojans "place" in the market. These boats were production - low to mid tier boats. They aren't considered to be in the same league as a Betram or a Hatteras. Having said that, I have seen just about every square inch of this very old girl and I'm impressed with it's construction quality and how it's held up after so long. After more than 30 years, I had not a single blister. The hull, stringers and structural elements are still in great shape. My fore deck and flybridge (which are cored) did have some soft spots that I fixed but they weren't causing any problems. That's a fairly common (correctable)fault. I would buy another one in a heartbeat. I think many Trojans represent a super bargain in a market thats already full of bargains.

Good luck with your search.
 
All I can say is that my F36 was a great boat and the original getcoat looked great. I got a lot of compliments on that boat.
 
My advice (if you had asked for it) would be to not think of what you put into her vs. what you could sell for, but instead compare what you have into her vs. what else you could get for that money. A customized, updated, diesel powered modern classic? Those aint cheap - anywhere.

So, is the flat-screen to starboard? :)

Are you SURE about putting the rails back on? It really is a cleaner look w/o them. I guess there's a safety aspect to it if you have "little ones" around.
 
You make good points.. and NO- I'm not sure about putting the rails back on. I love the look without them and my kids are old enough now to deal with the low sides. ARGHHH... your not helping!

And - Actually, the flat screen's ARE to starboard (1) and (1) in the berth.
