That's the mad looking thing. Last time I saw it it was parked up at Eastwood Rd Ind Est, years ago. I 'spose that was your place.

Here's a few of how ribs look in the 21st century.

300L fuel tank for an inshore race boat seems a bit big (am no expert). bet yerl be goin faster in the evenings! altho it dos seem a bit slow for the horsepower. i can "easily" (flat days) get 55mph out of my 200hp opti on my 7 meter xs rib and have seen 58-9mph on very flat days, but still a stunning looking boat. am very jelouse, always loved the vector that was parked in lymington with the black tubes n yellow 2 person console with a big merc n the back. good luck with it!!!! p.s do you use a stand off plate for it to get the prop away from the boat a bit. posibly prop height could be low as well. on the boat mad forum their is a guy posting who has a b23 race boat with a similar inboard set up. not sure of the engine but its a 2L i think and he uses a volvo leg. could be worth a look in. heres the link. http://boatmad.com/forum/showthread....ht=b23+inboard

For that much power I'd expect at least 60 + . As per Andy I can get my 7.5m Shearwater ( not the lightest boat in the world! ) to 50 knts full of fuel , 2 up - and thats pushed by a standard 200opti & prop. BUt if you are carry 300 litres petrol + ballast it coudl be why - still seems a bit 'light' on the speed front for that much power

not really got any way off accuratly measuring speed old drive was way to deep as in photo

The cleaver prop looks mean enough. Is that a custom Vector original fitment boat cover in green?

props a hoff also known as offshore (cleaver has straight trailing edge with very slight lip)
this prop has longer slightly oblong blades with flater front edge (produces stern lift)

The paint on the new leg has a hue of late '80s Soozook.
Hope it all stays on.

I think the guts staying in it is more of a concern.

Hi all,

I've owned this boat for 3 yrs, Trying to find out a little more about it, I see quite a few experts here. I know Peter Kidd designed it and Vector built it. I'd like to take it to France but unsure of the paper work as I can't seem to find a HULL ID Plate. It was built pre the requirement to fit them under MCA Small craft directive.

Does anyone know the in / out of taking it to France, VAT is another challenge I don't have the original paper work, I believe the boat was built for David Pratt in Portsmouth and he used to race it. I know the frogs are pretty hot on VAT and impounding boats.

Running an ETEC 225 HO, bloody great lump plenty of torque, probably a bit over horse powered now:-). The engine is racked quite high and the water pick up for my nose tanks interferes with the prop now. I'm thinking of changing it to a fuel tank to pump fluid / weight about to trim instead of taking on more weight to achieve the same result. Any ideas or done this before??

Attached a couple of pictures encase you know the boat.

Thinking of heading down the Silly Isles this summer as it removes the challenges above.

Cheers for now
Seb
