The decision to look at buying a 285 as opposed to 305 is simply to do with the tow-ability of the boat – you buy then total independence. Although secure mooring is easily available, security of your easily-removables still remains an issue in crowded harbours when you leave your boat unattended even for a few days. Looking at what the 285 is supposed to do in an ocean environment, a genset and watermaker may be of greater importance to the safety of the crew than most of the other "extras". The 305 certainly looks dependable enough to be taken to the really remote areas we have here in Western Australia but it is too big to cart around behind your (heavy!) truck without special licenses, etc... so the 285 would have to do all that the 305 can (you still need an F-250 truck or the like at least!), but with a bit less comfort space (not safety). A diesel genset and a modular watermaker (e.g. modular UltraWisper from Sea Recovery or Ventura 150 from Spectra, etc.) would then become very desirable "extras" in my book.
Does anyone know if BW made any provision for a hatch or space where one may install permanently a genset? or how it can be squeezed somewhere and would appreciate any help with info from the grapevine. The modular watermaker can easily be installed in modules in a variety of places, but the genset bay has to fulfil all the safety and operability criteria so you don’t buy yourself trouble.
Thanks people in advance and Merry Xmas.

Have you visited the Whaler website and checked the specifications on the boats? You might find the information you need there.

I'm sure our resident Conquest experts will be along soon to respond.

Congratulations on putting your very first post in the appropriate forum. Lots of folks stumble on that.

The diesel genset in my 305 Conquest lives at the back of the rear hatch. It is a "clean" installation with room to service the generator.
It seems likely that Boston Whaler will offer an optional generator for the 285. Have you checked the BW website?
There is room for a 12 volt water maker under the same hatch. We were going to install one but decided that the occasional use was not worth the maintenence nuisance of an occasionally used water maker. We been out for 4 days at a time and have not used up the 40 gallons of water in the tank. We carried extra fuel for our long trip and could have carried a jerry can or two of water.
Towability without permits in the U.S. depends on beam width. You will have to go down to a 26 foot boat to get one 8 and 1/2 feet wide that would be leagally towable without a permit. I doubt there will be much if any real world towability difference between the 305 and the 285. Either boat with trailer would weigh more than the 10000 pound tow rating of a 3/4 ton truck.
There is a guy who tows his 295 Conquest from Colorado to San Carlos Mexico once a year with his Ford one ton diesel truck. Some one tons are rated to tow 12000 pounds with a fifth wheel or gooseneck type hitch.
We purchased our boat in California and hired a guy to tow it to Mexico. I expected him to show up with a Kenworth. Instead he had an F-250 diesel, stock except for airbags and drove all the way without difficulty. I have a diesel Excursion rated to tow 10000 pounds. I tow my Conquest only locally for storage and service and it seems to tow fine.

The 285 is NOT offered with a genset. Another confusing thing for a potential buyer is that it is only rated for 450 horsepower. ( the same as the 255 ) To make matters worse, the whaler website says the 285 weighs 6200 lbs which is acceptable with 450 horsepower, but the 285 owners manual claims the 285 weighs 7200 lbs which would make the boat less desirable with 450 horsepower.

Has anyone actually seen or been on a 285 yet?

Why is it necessary to have a genset that costs $15,000? Doesn't it make the boat too heavy? Would you really use it that much?

I, like everyone else on the forum, know little about the 285. I have a 28/295. The key to the genset is the location of the fuel tanks. If the 285 tank is in the bottom of the boat, on the centerline you probably can't install a genset. As to whether or not you need a genset, only you know. I stay on anchor or in a marina without power for up to 5 days at a time, running my genset 2 hours a day. If I didn't have a genset I could run more batteries and an inverter, but then you need to run long enough to charge batteries or stay on shorepower long enough to charge them. Using a diesel genset has several advantages in the U.S.. Boats are built to comply with the Code of Federal Regulations. Many of these CFRs don't apply to outboard powered boats until you install a gasoline genset. When a gas genset is installed the requirements for Fire Suppression, Ventlation, and other requirements apply. I would think that a pair of 225 HP engines would give you no less than 40 Kts. I've had 225 OPTIS and now have F225 Mercury/Yamahas and get the same speed of 39 Knots even though the "experts" here report the Optis have up to 30 more horsepower. My boat weights 8600 LBS dry and I carry 600 more LBS of fuel than a 285, 300LBS of chain anchor rode, genset, a/c and and extra batteries.

I know these are old posts, but I recently purchased 03 295/28 with yam/mercs. Brian O. has told me what I did not want to hear, but still searching for other ideas on plane time w/heavy loads. Of course previous owner did not mention until I asked about plane time after the sale.

I would start a new thread in the performance section to get input on whether your engine setup and props are appropriate.

I have a 2000 watt Honda Generator which I use with my travel trailer when hunting in remote areas.
It weighs about sixty pounds and is quieter than the diesel generator in my 305. Like most things made by Honda, it gives me little trouble. It certainly has the capacity to charge the batteries, run the micro wave and a hair drier but not together and of course cannot run the air.
I have heard that Yamaha makes a similar capacity propane generator if one is nervous about carrying gas in a can and feels more comfortable carrying a propane cylinder.

Beginning in model year 2010, BW began offering a 4.0 KW Fischer Panda diesel generator as a factory option. It is accessed via the existing bilge hatch in the cockpit floor.
