Watch out for severe stress cracking problems: spray rails and adjacent to internal bulkheads!

I bought one new early this year after looking at many secondhand. Did not see any out of the dozen or so we looked at with stress cracks so I find that interesting. The basic boat has been around for many years as the 365 so is well proven. Sealine service is excellent (it's my 3rd Sealine) Suggest do a search on this site for S37 and you will probably come up with all the answers to the questions I was asking about this time last year.
If you are buying second-hand then look for one with a bowthruster. Also for subjective reasons the ones with Mercruiser engines do not sell so although you could pick one up cheap they are very difficult to sell on.
A great boat, loads of head room for a 6footer+ (my son not me!) Tons of storage space and very comfortable for 4 people.
No faults other than second hand ones are too expensive which led me to buy new.
Happy to anwer any other questions you have.
happy hunting

My last boat was a S37, alfie. Its a typical Sealine with excellent accomodation for its length and some nice design touches. Its not a bad seaboat and, with the right engines, it goes well subject to the usual caveats about outdrive boats. Mine had KAD44's and I found the engines noisy at speed
The one problem with the S37 is that Sealine turn them out by the dozen and discount them heavily to keep shifting them when new so there are loads about secondhand. The ones with smaller engines, ie. Volvo AD41, KAD42 or Mercruiser 220hp seem to take longer to sell on so, if you buy one of these, drive a very hard bargain. Best buy would be a 2yr old one with KAD 44's but still with the balance of the Volvo warranty left but dont pay more than £110-115k

Is that based on personal experience or hearsay?

S37 used to be the 360, not the 365. The 365 was a much bigger boat altogether, lots more space inside and out and two heads. I think "Tripleace" on here has a 365.
360/S37 quite attractive, but I found the headroom a bit limited and the cockpit a tad small for the size of boat.

Totally agree with Deleted User, in fact Mike was my biggest inspiration when I was going through this a year ago. I went for KAD43's because of their simplicity against the electronics of the 44's but that's a personel thing and I believe the 44's have been equally reliable. Early KAD42's had a reputation for broken pistons which Volvo beefed up but I don't know when the changeover year was.
There was a changeover from aluminium windscreen trim to SS about 2 or 3 years ago. The SS looks so much better.
That's all I can think of for now

Yes I stand corrected, the 365 was about 40 ft long I think they must have measured boats in a different way then, not including the diving platform perhaps. I think the 365 became the 380 or 400 Ambassador

I think one would have to be a little cautious with this statement. The hull is exactly the same (save for some changes at the aft end) as the shaftdrive 350/360/F36/F37. MBM has run an F36 and now two F37s. I took the F36 around Britain and dropped it off some pretty big seas without any structural problem. Have not been aware of problems with the sterndrive example either...but used to get pretty fed up when a friend with one fitted with Yamaha diesels turned in fuel consumption figures not much more expensive than my displacement Pedro on a Channel crossing!

Why do you need a bow thruster in a twin engined boat. Is mine or my last peculiar?? Does it not LBJ. ToMo?? Whats the need for this Bow thruster thingy?. Now I can understand if boat is 50ft plus. But I've not seen a twin engined boat that needs bow thrusters! What do you use them for?? What do they do? Much easier to take out the back end and just more or less forget about what the front end is doing. Or are you all still driving cars?? Still you back the carsinto most places. Then back them out. Seams most of you have different philosophy about parking or un parking boats??

Re: Why Bow Thruster
What it is with me needing a thruster on a 365 - and I suspect its the same with the S37 - is that the access door in the transom is to starboard, as is the easiest access to the foredeck. Hence I always try to berth starboard side to. This often means a stern first berthing and the thruster is dead handy for this.

Re: Why Bow Thruster
I have to say that triple ace can move in almost any direction and without the use of a bow truster.
this is becasue the outer legs (third engine in the middle) are further apart and this gives even great control and force.

Re: Sealine s37 vs 365
365 is 40ft long 13ft wide
same hull as ambassador 400, different top
365's in my opinon were built stronger and triple ace is unmarked as far a cracks and stress.
365 in waterline I think or
3 engines
6 6 bottle wine rack on board
5 full berths before you use the saloon double berth (7)

Re: bowthruster
INteresting that you say that you feel you would need a bowthruster over 50 feet. I feel the other way around - the smaller the boat the grewater the need for a bowthruster. Think about it - the weight (inertia) ofa boat increases in proportion with the cube of its length - but the windage only inproportion with the square of its length. Hence larger boats boats less susceptible to sidewinds, as I have found.
More financially minded - a bowthruster is seen as "making things easy" so any boat that could be bought by a 1st/2nd time owner will be seen as better with a bowthruster.
Maybe s37 are (for their length) somewhat lighter and higher, also meaning a thruater is needed.
Finally, in the highly select marinas, there is almost no space at all, so need bothrusters to spin about and possibly cranes to jump over things.

Re: bowthruster
It's the outdrives that make the bow thruster a necessity!
You've got much less leverage over the bow with the props aft of the transom rather than toward the middle like a shaft drive boat.
Get much past 35 feet on outdrives and manoeuvers in a cross wind become very entertaining, at least for bystanders!
Agree not so necessary on a shaft boat till 45 feet plus, then they start getting useful.

Haydn, if you've ever tried to manouevre a sterndrive boat larger than 30', especially in reverse you'll know why you need a bowthruster. The centre of rotation is way aft because the engines/props are aft mounted and any puff of wind blows the bow off and in a confined space so you cant just 'forget what the front end is doing'
With a shaft drive boat its a lot easier because the centre of rotation is futher forward and in any case shaftdrive boats tend to have a better grip on the water because they tend to be heavier and deeper drafted.

I dont think so. The 450/T46 and 390/410/F43 are John Bennett designs and I think the 360/S37/F36/F37 is an internal Sealine design

The 450 and 390 were streatched John Bennett hull, at a latter date the original drawing were used to build the 360.

Dunno about that Mike, I did quite a bit of manouvreing of a Sunseeker Martinique over the Summer positioning the boat in photo-shoot sessions and although fitted with a bow thruster I didn't need to use it.
