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. http://rib.net/forum/showthread.php?...highlight=Vmax

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
