I talked to an woner of the 390 recently. He said the only real difference is that the swim platform on the 390 is molded into the hull and is therefore part of the boat and so the total length must be included. The 350 has an 'add-on' swim platform and is not part of the actual boat hull and so the swim platform is not included in the length.
He said he didnt like the handling of the 390 because the prop is in the same place as the 350, which is too far forward for the 390.
This info was given to me by just this one owner. Have no idea what other 390 owners have to say so don't put too much stock into it.

Not really a Mainship issue, but that is not correct. Molded in or bolted on, the swim platform is inluded in the LOA. You can't get a 30' boat with a 3' bolted on swim platform into a 30' space.

In 2000, my boat was built and sold as a 28' boat. Even the documentation says that. Later, the same model was sold as a 31' boat. Same design, same swim platform.

As far as I know, they are the exact same boat and it was a marketing deal. The main competitor to the Mainship 350 was the Albin 36. The only problem was the Albin was really a 33 footer with a 3ft swim platform. So not to be outdone, Mainship included the swim platform in the overall "model length" somewhere around 1997/98. That is why you will see people refer to them as "350/390"....same exact boat.

Yep same boat.

They started calling it a 390 in 2000, the year we bought ours.

There were some minor changes inside the boat.

Still have ours after 13 years, running great.

Yes they are the same boat, same hull. They changed for "marketing" reasons.
The 350 owners pay less at a marina than the 390 owners.
Other than that whatever other changes are only model year dependant and have nothing to do with the basic boat.
For example there are several different engine brands/horespowers as that changed thruout the production years, same for gensets, etc.

That depends on their level of honesty.

As I posted above, my boat was built and sold as a Camano 28 but it's now called a Camano 31 and it's probably 31' long. I've never measured it.

When the marina guy asks "What is the length of your boat, Captain?", I just can't bring myself to lie and say 28'. On a face dock, 31' is 31'. You can't fit a 31' boat into a 28' space.

I did manage to negotiate a foot off my bill at my home marina but the slips are all the same size and the minimum is 30'.

If true, and the platform extends the hull from 35' to 39'; the resulting boat may have a slightly higher hull speed by a couple of knots in displacement mode. Maybe carry a little more weight too.
I agree the relatively more forward position of the prop/rudder could make handling different and not in a good way.

USCG Boat Documentation Center defines a boat's length overall as the length of the hull without swim platform, bowsprit, etc. Marinas define it as the total length including everything. USCG Marine Safety Center (MSC)

Some boat builders (like Mainship) seem to use the labeled-length as a marketing tool.

The Coot's labeled-length is shown as both 35 and 36 feet on the builders website. Actual length is 35'8" and was used for USCG boat documentation purposes. With bow railing and folded swim platform, its marina-defined length is about 38 feet.

At some point between 1999 when my boat was built, and 2012, the entire industry switched to including the swim platform, anchor pulpit, etc, in LOA.

They are the SAME EXACT BOAT....hullform and all.

And to the above statement....LOA is LOA. What the manufacturer decides to slap on the side of the boat(ie the marketing brochure) has nothing to do with it.

As said before, they are the exact same boat. Hull #1 was built with a standard bolt on platform and could not get the bow down. Mainship then went back to the drawing board and added the platform. The platform is bolted on and glassed over. It has a bit of a strange shape under the waterline that acts some what like a trim tab. this helps push the bow down and since it is below the waterline adds to hull speed. The forward position of the prop probably makes handling a little strange when docking, but i don't even notice it and with the bow thruster i can put it anywhere. I think when the changed from the 350 to 390 designation they moved the fridge about 8" toward the stern giving more counter space forward. thats about it for the difference. Mainship says they changed the designation from lwl to loa because thats the way they do it in Europe. I think they did it to sell a 35' boat for more money. (they now call the 34 a 395)
Anyway, i've had the boat for about 6 years and highly recommend them.

Grand Banks did this a few years ago. They came out with a new model called the GB44 which used a different hull than all the previous GB models. After the boat had been in production for a couple of years or so they said they were adapting the ABYC method of measuring a boat and the model became the GB47 which is still in production today. Same exact boat, just a different way of measuring it.

On the other side of the coin they have just replaced the GB41, their pod-drive boat, with the GB 43. This is also a pod-drive boat but is a slightly longer (in the cockpit) version of the now-discontinued GB41. So in this case the boat actually got longer, it wasn't just a different way of measuring it.
