Sorry Tim, didn't realise Marcus already had the boat. Thought he was building/hiring/borrowing etc.
One problem (a big one though) that a petrol boat brings, is refueling. The number of marinas with handy petrol pumps at the dockside is quite low.
This boat, with twin 200's sounds like it will hold a bit of fuel and he will need to plan how to refill his tanks.
Without trying to be presumptious, if there is anything I can do to help, please put us in contact.

Hi Brian
Daft question reguarding the round the country rules, can you refuel at sea
or this outside assistance?
Not quite suggesting RFA's positioned round the coast or refueling whist running but it could save time.

Hi All,

When we looked at it (not in huge detail, 'cause we lost heart ), we came up with the following figures/schemes/solutions.

1600 ish miles in under 33 hours needs average of 49ish Knots. Using twin petrols, in a 9metre RIB, running pretty much WOT for hours on end, is going to drink enough juice to keep OPEC happy. We "budgeted" on 2 litres/mile/engine, which is pretty much what my single 250 uses WOT plus a little in hand. We looked at big under deck tanks and big on-deck drop tanks with big cross tank feeds and pumps to enable boat balance to be maintained, as we reasoned we would be driving the boat bloody hard and needed all the advantages we could get.
To put the weight into perspective, we (roughly) assumed that we would be using 6 tonnes of fuel. The question of re-fuelling is therefore absolutely essential as you say.
Our plan was to have made (by a well known Midlands fabricator ), a large number of deck tanks of a size that could be man handled full to minimise down time for refuelling (remember we needed a bloody good average speed)
Say we were carrying 2,250 litres under deck, we would have needed another 4,200 litres in tanks. We allowed the maximum size that a tank could be was 150 litres, so that they could have been man handled when full. We thought we’d put 6 on deck at any one time using a system of quick disconnects and mounts plus a lot of valves and pumps! This would give us a requirement for 4 fuelling stops at 790 then every 200 miles or so. We figured to make the stops “hard” against a suitable quay/shore side to facilitate handling a tonne of fuel at a time, rather than “wet” from boat to boat as we were concerned over the logistics. The difficulty of finding “volunteer” to sit on our fuel “stashes” and handle the donkeywork was alarming, but easier than co-ordinating boats!
Even the costs for this amateur attempt, including the assistance from Shakespeare Etc, were pretty great and when someone announced a well backed venture, we decided to let it go…

Good luck to anyone who attempts this record

Having had a look at the website and seen his boat, perhaps he should advertise the record attempt as the "round uk record attempt in an outboard powered minibus"

Hey Dirk, you forgot to add "with a rubber ring round it"!

Seriously though, it looks like a serious bit of kit for taking passengers on trips.

Edit: interesting to see seat belts are fitted. I guess they're pretty confident the boat won't capsize...

Just out of interest, given the record is 33 hours and Marcus is talking about doing the trip in 91 hours what record is he hoping to beat.

If he sets up a class of "RIB with most seats in" then he stands a good chance

Cheers

Mark

Jelly.
It depends what you mean about "record" and "rules".
For a proper understanding, you must consult the RYA (or Alan Priddy). My understanding is that if you go for any "official" record you can only refuel in port at a properly organised refueling station for safety reasons.

But hey, whats all this talk about records?
If Marcus wants to go round and raise money (and enjoy it), bloody good luck to him. He do do whatever he wants and make up his own "rules".
This is, I understand, the purpose of the endeavor.
If your purpose is breaking the official record, then I suggest you start again but with a completely blank sheet of paper!

That'll be the same link timofengland posted in his very first post, Brian.

Yeh, I like the sound of that, although I not sure about the "do do" bit. But let me know if he does do do it and I'll send him £20.00. And stick Jono down for a score as well!
