Hi Guys,

My mate who is looking to upsize from his Bayliner 288 has viewed and is very impressed with a yr 2000 Sealine F37....

Fitted with twin VP TAMD43's 230hp with less than 350hrs showing....

What sort of performance can he expect and are there any issues concerning this setup he should be made aware of?

He is just about to shake hands on the deal subject to survey.

Thanks in advance.
Rob.
 
What Nick said. We hit 30 on sea trial with no water, no stores and fumes in the tanks. Normal cruise is 23-24 ish at around 1.2-1.3mpg. No real issues with the engines, but the electrical system needs attention (nothing major, and I can happily give more details if needed).

We're into our 5th season and think she's a great boat.
 
Just agreeing with Nick and Wiggo. I have the S37 therefore lower and lighter and get 32 knots flat out on KAD43's but spend most time cruising at 22-24. Like the S37 loads were made so no issues that I've heard of. Lovely spacious boats, buy buy buy!
 
We had 2 x F37's. First had KAMD44's @ 260hp and the second had KAMD300's at 285hp. Fully loaded the second boat could still hit 30 knots but the first topped out at about 28.

I still think they are great boats but we did suffer head problems on the later boat and also on an earlier F36 with KAMD42's.

If I understand it correctly, the 43 is a 42 with some of the 'issues' sorted out. Not heard any particular problems with the 43's
 
Another agreeing with the above.

I have cruised miles in a Sealine 350(more or less an F37) with Volvo 230s and even further along side one.

Cruise speed was 22-23 fully loaded, very good boat well designed sea boat with typical sealine tardis accommodation, 230 HP is adequate.

Steps to the flybridge can be intimidating in heavy seas.

I think it had the 42 series volvos which used a bit of coolant water but wasnt a problem.

Anyone know how 230 hp is adequate for a 36ft Flybridge Sealine and yet is no where near adequate for a Princess 360 , mine used to have 220 hp but had to be upgraded to 300 HP ?
Link to my boat here http://sites.google.com/site/princess360felix/ it looks more or less the same size but needs loads more power.

Both listed at 7500kgs so it's not weight. Can only guess that it's down to hull form. Maybe the Sealine had a shallower vee. Is the Princess noticeably better in a chop?
 
I have a Sealine 360 with 230 Kad42's. ie. same as F36

We criuise at 20 - 22 ktns most of the time with 6 -8 people, full fuel, full water, tender, outboard, genny and all the other stuff we seem to carry about

This seems comfortable although she will push mid to late 20's if we were light.

Economy is 1.3mpg at 20 - 22 knts.
 
Rob, can't comment on the engines - I have KAMD300s similar but not the same - but I've had my F37 from new (2002) and no real issues to date. I would definitely recommend. It's a very user-friendly boat and he'll have a lot of fun with it.

There are a few minor details which in a perfect world I would change, but you'll find that in any boat.
 
Meant to add, Rope cutters will in my experience drop the top speed by at least a knot, and would burn a bit more diesel. I get about 1.1-1.2 mpg - it should certainly do better than that with the 230s

I believe it is significantly more comfortable in a 6/7 but cant be 100% certain as you never get the opportunity to be in two boats at the same time, what is even stranger from the above is the Princess manages better mpg with twin 300s compared to twin 230/260, oh well getting a little side tracked, the F37 is certainly a good all round boat with reasonable residuals too.
 
Not sure anything sub 50' is going to be 'comfortable' in any way shape or form in a F6-7, to be honest. We've been caught out before now in some very wild stuff and the F37 is a very comfortable boat - I've had breaking waves on the starboard beam level with the flybridge guard rails. The boat felt very safe, and although she was pushed around, she felt very much as though there was plenty in reserve. The only damage was a small star shaped bite mark in the upper helm seat...
 
I think the Princess is listed as 9.5 tonne ( http://www.princess.co.uk/heritage-docs/Princess-360.pdf ) so it could be that which helps with the ride and requires bigger engines.

No idea why the Princess weighs so much more, I best check around to see if there is any ballast to chuck over the side, I once slept on a Broom that had rubble under the bed , chunks of concrete and broken slabs.

Interesting. Your link mentions 8.5 tonnes, the brochure I looked at said 7.5 tonne and you mention 9.5 tonnes. Obviously if it is heavier, that's your answer, but it does go some way to explaining why boat weights are such a hit and miss affair as dictated by another post hereabouts.
 
The F37 is 8 tonnes dry. So that's no water (500kg for the main tank, 100kg for the flush tank, 100kg if the holding tank is full), no fuel (750kg or so), no engine oil (20kg) and no stores. We had to empty the water tank once in Christcurch as the crane alarm was going off at 10 tonnes...
 
Yup, I recall when mine was hauled up - I thought having taken pretty much everything of it it was 8.75 tons - I think Sealine's weights are very dry! Our f37 has ploughed through some pretty evil stuff. I recall MBM's skipper was well impressed with the f37 which looked after them in all manner of stuff your average skipper wouldn't have even contemplated.

I don't suppose we'll ever know whether one is objectively better than another. It would be interesting to compare side by side in the same conditions. I suspect the P would have the edge, but the F37 is so user friendly in so many other respects.

Princess 360 is nearer 40ft loa maybe thats why
