Here's a little more info on my 25 1/2 foot model 759 Stabi that you asked for.
The pictures I'm sending now are from August when the boat first got here and he had the twin 150 horse Honda's installed. The boat and trailer look quite a bit different now. Notice how low on the trailer the boat sits. That is the way they ship them up to keep the center of gravity low. Now the bunks have been adjusted up to get the boat up off the trailer fenders and also the axles have been moved back to accommodate the weight of the 150 Honda's. Other changes that have been done are that it now has a radar arch mounted on the house all the way forward so I will have room for my 10 foot tender raft that will sit behind the radar arch. I bought a ten foot "Gary King Alaska Inflatables" raft. To power the raft I bought a 2 horse Honda. It also now has Scotty Down riggers mounted on both sides which are easily removed when not being used. Also there is now a 300 lb. light commercial model "Safe-T-Puller" shrimp pot puller (that is also easily removed) bought from Donalson Co. here in Anchorage. I didn't want the rod holder on the house on my 759 because of my raft. I have my VHF antenna and a satellite phone antenna both mounted up forward with an extension on my sat phone antenna for better reception and also to match up with the height of the VHF antenna to keep the lines looking nice. There is now an anchor and all related rigging installed. Inside I have doubled up on bilge pumps and switches. There is also a Wallace diesel/kerosene stove, refrigerator and marine head. I also had an extra fan installed to keep the windows fog free. For electronics I went with Ray Marine E Series, which includes a 12 inch display, GPS chart plotter, 48 mile radar, sonar or depth finder and a Ray Marine VHF. All of these items are integrated and visible on the 12 inch display at the same time except of course the VHF. I also had Travis install a mount that is custom made for my 9505 Iridium satellite phone, and of course run a wire to it from the antenna. And then I went with a full instrument panel including a fuel flow meter so I can find my most efficient cruising speed.
As far as ride and fuel efficiency, I haven't ran mine yet but I have done extensive research. The ride should be better than most due to the pontoons that will give you a much more stable ride. This boat should inherently roll less that any other boats out there except for maybe the ACB Boats, which are actually a throw back from Stabi Craft. I feel Travis at Ron's Honda has been very knowledgeable and honest with me in the past and he insists that due to hull efficiency and Honda Outboard design I should get a 300 mile range out of my 100 gallon tank, which equates to 10 gallons per hour fuel burn at a cruising speed of approximately 30 miles an hour, or in another way 3 gallons per mile. Some on "The Alaskan Outdoor Forum" don't believe it will be that efficient, but time will tell. By the way at WOT (wide open throttle) this boat will due in access of 50 miles per hour.
I'm just going to leave my boat in storage until May. (economic crisis is putting a squeeze on me right now) It is presently sitting at Ron's Honda in Soldotna. He may show the boat at the boat shows this winter and spring. I'll post info when I know for sure.
Total cost, completely rigged and ready for launching....$129,000
Maybe Kaisersosai will post some pics of his new 859 Stabi, and add to the info I've posted.
