Can that really be right?? My Mitchell 31 had a 320hp Nanni engine (6.420) - at a cruising RPM of 2800 rpm she used 35 Ltr / Hr giving up to 16 Kts depending on load, conditions.

Hi rob,

Always worked on the basis that the old d3 Volvo 170-190 hp used 4 gals / hr, as in sealine 23 etc giving about 4 mpg.
At 20 kts, so I was as surprised as you when I read the MF 805 blog.

With reference to the engine comparative test in Mbm feb 2012, the gold standard of tests, they list 250 hp Volvo, cummins and yanmar as 4.5 gal/ hr at 2500 revs.

Maybe the MF 805 has a massive hump to get over at 10-12 knots?

Out of interest in the 350 hp range the figures are 8.5 gal/ hr at 2500.(38ltr/ hr), which would match up with your figures exactly on your Mitchell 31.

Or maybe modern hulls aren't very good!!!

No can't be. My Beneteau 9 series with KAMD43 used 25-28 litres per hour at 15 kts. Mind you, at 12 knts a MF805 won't by planing but will be approaching the hump I'd imagine.
 
The scandi walkarounds (botnia targa, minor offshore and nord star) might be worth a look. We made the same transition as you a year ago and looked very hard at the seawards. Our conclusion was that the little ones (23/25) were too small to contemplate a wet week in the West Highlands and the 29, while giving just about enough space for viable cruising is just too fuel hungry. Most owners I spoke to claimed 2mpg, but then admitted they never went over 8kts. After lots more looking we went for a NordStar 28 which gives 4 good berths, a really nice comfortable wheelhouse, cruises at 24-27kts and returns 3mpg (1.4L per nm) while doing it. Keith Stewart's website gives an account (http://www.nordstar.co.uk/?page_id=347 ) of an owner with a 24 who has cruised from N Ireland to Orkney, so they seem OK on the sea-keeping front ! We've certainly been very happy.

Hi Bill,

Is that a semi- displacement hull?
 
Thanks Bill,

I took a quick look at apolloduck and the boats you mention all seem to be well out of my price range unfortunately. They look just the job but a little pricey for me!

I am currently looking at Saga 26. This seems to tick all the boxes and there are a couple available.

Thanks for the suggestion

Can you get a Nordstar 28 for the OP's £35k budget ?

I'm ashamed to admit that I missed the OP's budget on first reading. I think the answer is probably no -- though if you are prepared to go to Scandianvia there are some oldish ones that might get closer. However, the reason I gave the link to the account of Mara's cruising is that 24's are a lot cheaper, and I wouldn't be surprised to find one near the stated budget somewhere in Europe.
 
Hi Bill, A quick look on www.finn.no does not show much below 880K NOK or 100K GPB for a nordstar 28. I would be happy to buy in Scandinavia as I work in Bergen but Unfortunately they are simply too pricey for my pocket at the moment.

lovely looking boat though!
 
If you are going to drop down to a 7 Meter Boat I have a Norwegian Skibsplast 700HT.with Inboard 130 Yanmar Diesel which planes at 12knots and continues through to 25knots. Very few with the Hardtop around Looks a bit like the Flipper but without the outboard. £20,000. Low Hours. Service History. At just over tick over it does 7 knots using less than a gall per hour. (because it has a big 4 blade propeller) And there is a superb trailer.

Does anyone have any experience of the Flipper 717?....
Click to expand...

The flipper 717 have a good reputation for being well and sturdy built and when introduces she was one of the first ones with a large sliding roof....

The engine "OMC Cobra Diesel" I seem to recall being one of the first "electronically controlled" marine diesels introduced by the company we now know as Steyr (Monoblock diesels).... some time in the early '90's ... I cannot say anything about the reliability of the engine and hopefully someone else can comment... but what I do know is that she is fast revving for a diesel (4400 RPM WOT)... which is high for a diesel of that age.

In respect to propulsion, I think you will find that the engine (at the stern of the boat), is connected to an outdrive (sterndrive) which from my recollection you wanted to avoid. the make and model of this drive would be something I would want to investigate further, but if it is connected to a OMC Cobra (which some of those 3.2L diesels were), there are some known "gear issues" connected to the drive... (amongst them very sensitive to cable adjustments from my recollection)....
 
OMC Cobra drives were actually very good units. AFAIK they became the Volvo SX drive of today. The only problem with them was that they were very susceptible to incorrectly adjusted lower gear cable and needed a certain amount of skill to be set up properly.

The OMC cobra diesel is a very rare beast. Not sure what engine it was based on so you would need to find that out for availability of spares. OMC went under about 10 years ago. Some spares are available from Bombardier Recreation Products who took over and carried on with the Evinrude name. But as OMC sterndrive engines went out of production around 1990, spares for any of them are getting harder to find. The exception to this is generic spares for the V8 motors. If the diesel is in fact a Styer, spares availability for the engine should be ok. The drive will probably be a King Cobra and spares for these may well be hard to come by.

My take on it is that with an OMC diesel, the Flipper, as nice a boat as it is, is overpriced.

One important point to mention! You won't be 'Rich' for long once you get the boat.:rolleyes:

Too right. One of my nephews said to me a few years ago 'Cor, you must be rich to own a boat'. I replied 'No, I'm not rich precisely because I do own a boat':D
 
Does anyone know of a guide to motorboats? I am finding it a little difficult to gauge the quality & type of boat from the manufacturer. If we think about cars, I know exactly what to expect from a Ford, VW, Skoda etc but have little feeling for Jeanneau, Benetteau etc.

Is there a decent idiot's guide out there?

thanks

Hi Rich,

I only joined the forum recently, and was totally at sea (excuse the pun), but the formurites put me to rights pretty quick.

Here's some if my findings:

Work out boating costs per hour, not mpg. (Engines use x/ gals hr)
Day boating or sea passages .
Hardtop or open.
Planing or semi/ disp
New or old

......that's pretty much it. I've bought a small power catarmaran, best of both worlds.
