Christian, the owner has asked me not to give away her location at this time as it is on a private birth and the other boat owners may get a bit twitchy if there were unplanned visits to her. However it is safe to say that she is still on the south coast awaiting further work.

She did deteriorate quite quickly when she was on the Hamble but then most things do when left alone for ten years. When my mate bought her in 1999, he was fully aware of the scale of the project and to his credit he has done a fantastic job, mainly on his days off of work, to bring her back from the brink.

Although there is still plenty to do what with fitting new engines, gear boxes etc. most of the serious structural work is complete and with luck this time next year she will be ready to go.

Cheers, A76NJK

Christian,

Its a shame that 2753 will have to wait a bit longer for her rebuild but i'm sure it will come. It would be fantastic to see a pair of Mk1b's in action once again.

2751 already has a pair of 215hp Perkins 6 cyl Diesels which I suspect would give displacement speed or slightly more, say 8-10 kts, but the plan is that the new (possibly reconditioned/remanufactured) engines will be equivalent horse power to the original i.e. 1500hp Diesel V12's. This should allow the original performance to be achieved although hopefully having only a fraction of the original Griffons fuel consumption. Safety is a big issue also, so having a couple of thousand gallons of petrol sloshing around would probably give the insurers a heart attack.

There are a number of issues to overcome though, not least financial. This size of Diesel engine weighs in the region of 4.5 tons each plus gearboxes etc. as opposed to the Sea Griffon weighing in at less than half that. However less fuel can be carried as the Diesel does not have the enormous thirst of the Griffon. Stronger barers may be required and a host of other things but I am confident that these problems can be overcome.

This is likely to be a big project and may cause a bit of a stir when she is relaunched in her original colour scheme. Nearer the time of the work beginning I will post more details and anyone who may be interested in having a look will be welcome. 

Cheers

A76NJK

Hi A76NJK

She will provide quite a spectacle if the big diesels go in,although weight as you say will determine whether or not she will "get up on the plane".I would have thought that she'd manage to "labour"with the current powerplants.Here are the links to the pics I mentioned

Saw an advert for 2 Caterpillar 3412c 1000hp engines.
Asking £40,000 and not even reconditioned!!  I just about fell off my seat.  (http://www.boatsandoutboards.co.uk/view/F88404/)

Saw a spec for a Caterpillar: 3412C Diesel Engine ( v12 27lt ) rated from 425 - 1250 bhp (1200 - 2300 rpm). Dry Net Weight, (approx) 2415 kg/5,324 lb

Apparently the Griffon (V12 36.5lt) only weighed in at 2100 lb

Is this about right?  If so, well .......

Don,

Thanks for that. I've been looking at the Cummins 38 litre V12 which as mentioned tops the scales at 4.2 tons with the heat exchangers.

The new trade price for this sort of sized engine fit as supplied by the manufacturers to a well known Channel Island boat builder is in the region of £200,000 for the pair excluding installation and VAT!

Hello A76NJK

Re powerplants for 2751,an idea may be to charter MGB 81 for a few hours and see how she goes (40 kts apparently) with MAN diesels.

Hi A76NJK

Have a look at http://www.resale.de/angebotelinkold.php?gruppe=1602&off er=1

and

http://www.dieselenginetrader.com/index.cfm?fuseaction=Recen tEngines.Last100Engines_menu

Some big (some marine) motors that seem cheap (in relative terms).

www.dieselenginetrader.com has (36) 500hp @ 2000rmp V12 (GDR)  $12,000 NEW in Belgium. Weight 2200lbs He may have bigger/better!!
I never heard of them (Motorenwerke-Wurzen) but they're all German now.

Hope this helps,

Regards

Don

Don,

Thanks for that. I have registered with the company and inserted a free advert. Lets see what turns up.

Re Advert  17152  on www.dieselenginetrader.com/i

THREE x 500hp NEW V12's for £20k+vat all in sounds awfully cheap (from anywhere)!!   Even though they are listed as 'Marine', they are probably generator engines.

I've emailed the  dealer in Belguim for specs.  I'll post any reply.

Cheers

Don
