Default What CC 29-34' has the most range.

What configuration (engine/boat) center console 29 to 34 ft has the most range. Twin outboards only.

Too many variables such as size and number of gas tanks, size of engines, how they are run and the load of the boat.

More range - just add another fuel tank / fuel bladders.

If you are refering to fuel economy. It is a balance between ride and speed.

All standard tanks. 32 reg, 32 contender, 29 Jupiter twin 300 4strokes on each. Which will provide most range at cruising speed.

From what I read on THT, Fountain's would be the most efficient. In terms of range though the 30 Hydra Sports Vector would have to be up there solely because it carries approx 300 gallons but is certainly not too efficient.

As an aside, I recently saw a performance report on an Intrepid 310wa with twin 250 Suzuki's and it was impressive. 116 gallons of fuel, 20 gallons of water and two people it did 33mph at 16gph and 2mpg. At 46mph it was 28gph at 1.7mpg. With a 215 gallon tank for a boat that size it's impressive. The same hull with 300 Verado's comes in at 1.8 and 1.5mpg at those speeds. The CC versions would be even better.

"Most range" is a tough question.
Lots of variables.
However, all manufacturers should be able to give you some stats.
Here's mine with SeaHunter:
35 W/Twin 300 Yamaha's
Cruise at 3500 RPM'S, 31 MPH, 15.1 GPH, 2.1 MPG
35W/Twin 350 Yamaha's
Cruise at 3500 RPM'S, 37 MPH, 23 GPH, 1.6 MPG
29W/ twin 250 Yamaha's
Cruise at 3500 RPM'S, 29.8 MPH, 11.9 GPH, 2.5 MPG

Now, we're V hulls, run on a pad, 24 degree deadrise at the transom.
We're Kevlar hulls, lighter, more efficient, than an E glass layup, however also more money.
The load and fuel differed some, but these numbers are pretty accurate, although not gauranteed because there are so many variables.
Hope that helped you some.

Default I'm sorry, I left out.............

.....our 29 has a 250 gallon capacity.
Our 35 has a 377 gal capacity.
That info is required for you to establish range.

The 35 W/350'S was tested with 160 gals of fuel, 2 people, salt water, 2' conditions, 0 elevation, 84 degree water.
WOT was 66.1, and 67 GPH, 1.0 MPG.
Better to run at cruise, huh?

The 35 W/300'S was tested with 60 gals of fuel, 2 people,2.5 conditions, salt water, 82 degree water, 0 elevation.

Thus, in fairness, I did say the loads were different, and it's fair to point out the specifics.

The family that originated SeaHunter are not the typical boat manufacturing background. They come from the aviation industry and have quite a different mindset as to efficiency, materials used, design and such.
Kevlar hulls, the use of carbon fiber, 5.5 pound density foam core thruout, the entire hull, and the hull running on it's pad, which also incorporates a pad with the strakes, goes' to their airplane thinking.
Much different than anything I've ever been involved with, a real learning experiance for me, and quite fascinating for me to learn, well, do my best to learn.

My Bluewater 2850 gets 1.6 at cruise. It has a 250 main tank and 2-45 side tanks.for a total of 340. 1.6 x 340 = 544. That's enough for me unless I try to cross the Atlantic;?
