Are these two boats related in anyway (I know often the same hulls follow as they improve the range) or are they completely seperate boats.

How does the 350 compre to the F37 in terms of size/layout etc etc?
 
350?? Not sure.

The 360 became the F36, which is the same as that one that hit the rocks and sank on the delivery trip. Similar size and layout to F37, but hull / superstructure and styling are different.
 
Ok, maybe its a 360 (advertised as a 350) layout looks pretty close to the F37.

Its a 1993 bot if that helps?

No you're right. Looks as if the 350 was the predecessor to the 360. Looks identical to 360/F36 to me, other than interior styling.

F37 looks different, has different hull. All are similar size / layout.
 
Thanks Halcyon. Is the F37 completely different or a developement of the 350/360/36?

The other thing is, this boat has been re-engined with KAMD43's. At 230Hp each, is the boat going to have enough go or will it be sluggish? What engines would it have had originally?
 
Had the 360 statesman 1994 last boat ,the 360 has diff saloon windows ,diff fly layout and overhang, diff wood effect inside, 350 has grey effect, 360/F37 wood effect, I had KAD 43 27knts start of season 22knts at end, I re engined with Nanni 320s and got 31knts, cruise 27knts see add jaykaymarine.co.uk just sold gone to Belgium.
 
I may be wrong but I think the f37 is pretty similar to the f36/360/350 below the waterline. The styling makeover above the waterline was pretty extensive.

27knts WOT 3850 cruise 22 about 3400 the day I took the boat out for a sea trial, when I sold the KAD 43s in November it would only pull 21.5knts, the guy buying the engines brought his engineer with him and he was happy with engine performance it was just end of season full tanks needing a scrub, last out in April for afoul. Great accom, good sea boat, would have another having previously had Princess 410 , Fairline 31 , Draco 34 fly ect. My 360 was 1995/6 not 1994 too much scotch
 
My original school boat still with us, is an F36 same hull and ss as 360 statesman, 360 turned into F36 which only ran for one year 98-99 then they brought out the F37.

second school boat (now sold) F37, restyled ss and interior, access to engines not so good. F37 I believe has longer bathing platform than F36, and they reshaped hull tunnels to extend further aft hence longer platform too.

F37 (ours anyway) always down on speed next to F36, with same engines.

Both boats vunerable to slowing once bottom dirty. F37 especially we had our props reworked, as after 3 months in the water she would have a bit of trouble keeping ont plane once loaded with 4 students and an instructor and full tanks.

She now planes easier but is even slower, 22nkts

Best speed in F36 27.5 F37 25.5

(each has 2 x 230hp Kad43's)
 
Ar,nt all boats subject to performance loss? Especially up the Hamble where your boat seems to suffer after only a couple of months. I,m not so much worried about the performance as to the lack of effecientcy. As my last 6 trips since the end of November have all been at night after dark the reduction in speed has not been missed. You get a lesser sence of speed from the fly until you come down the back anyway. Sport boats are always that bit faster for a similar model [and a lot colder this time of the year] and feel a lot faster for a given speed due to your close proximity to the wet and cold stuff unless your in the Med. where the water is a tad warmer.

Indeed they are Dave, however I have noticed that despite the F36 for instance being one of the busiest boats in the marina, three months after a bum clean, she is more inclined to lose cruise speed than say my Princess.

F36 after three months down 4-5 knts, Princess 560 after a year down 4.5 knts,

the Princess after 3 months has only lost couple of knots. I believe it has something to do maybe with the size, torque of engines, and ease with which the hull planes. IMHO and experience of course

The Princess planes seamlessly from about 13-4 knts whereas the smaller boat needs the urgency of the compressors to get her over the hump at the same speed.
 
My cruising buddy had a 350 for 3 seasons, it was very impressive.
I have cruised along side it for 2500nm and cruised on it for 6-700 nm

It had Volvo 230 hp

max speed loaded 27knts
cruise speed 22knts

A good sea boat, fell comfortable in seas.

Petty faults ( I love the boat and I would have one )

The steps to the Flybridge are open and scary when it is rough.
The boat is so smooth onto the plane it is disappointing in that you do not leap out the water and onto the plane like a sports boat.

The upholstery was made of cheap material and needed replacing.

Gets my vote /forums/images/graemlins/smile.gif

I have seen it berthed alongside an F37

Looks the same size.
The front window is straight compared with the F37
Flybridge is shorter than the F37
Two round Port holes give it away as 350.
350 has a smaller bathing platform
 
FWIW and it's probably stating the obvious but I think it is boats that feel a bit underpowered that suffer the most speed loss in the Med. IMHO 2 x 230hp is not a lot for a 37ft shaftdrive boat especially if it is in Med spec with gennie, airco, pasarelle etc. I have the same prob with my boat which is probably a bit underpowered considering the amount of heavy junk on it. When everything is clean and the boat is trimmed correctly, it reaches 27.5kts but as soon there's a bit of fouling or it isn't trimmed right, the top speed can fall easily 5-6kts. In fact, with heavily fouled sterngear, I have seen no more than 16kts on one occasion. So, I think with a Med boat, it's important to choose the biggest possible engines
 
Yep, that inuitively sounds right, as we all know it's not a linear relationship between speed and power for a planing boat, so if you need proportionately more power to get to the higher speeds, it follows that the speed will reduce by less as the power drops off again due to fouling or med heat.

Consider a shafts boat boat doing say 23 kts, and you add 20% more power, and that may take it up to say 27.5 kts. Then add another 20% power, it almost certainly wont do 32 kts, probably more like 30. Then consider the same in reverse, a boat capable of 30 kts at WOT losing 20% power due to med heat or prop fouling will do 27.5 kts, and the same boat, with smaller engines, capable of 27.5 kts at WOT, also losing 20% power may fall to 23 kts?
