Problem was, once on the plane, it wouldn't steer, and they tried everything, including moving the console, tanks etc. The manufacturer even came over and tried, but he couldn't solve the problem, in the end, a much lower hp motor was fitted, and the boat was sold off cheap!
Dick,

I am glad to hear other peoples opinion, but please try to get out complete facts.

Poole Boat Park imported the second RIB555 ever made and they only imported 1 unit. That was because the owner, George, suddenly lost the rib-guy he had had for 15 years at the yard. So they simply didnīt have anyone with knowledge about ribs, and got out of that business. Actually the RIB555 was initially designed and created because George asked me to.

The "tripple 5" is a DOUBLE stepped 5,5 rib designed to take very, very small engines and get it going cheaply when you buy, and when you use. One well known franch magazine did a fuel consumption test, and found it can actually make 5km with only 1 litre of petrol at planing speeds. Bet you will not find any other 5,5m rib capable of that.

The 555 was not intended for the huge engines needed by most other ribs the same size. The engine Poole Boat Park tried to put on against my opinion was a 75 Evinrude which really pushed the envelope. I still have a GPS recording saying we topped out at over 44 knots which was not the intention with that boat. It simply was not in the water anymore. You could steer, jump waves, whatever. But it chine-walked at 41 knots+, which is perfectly natural for any stepped hull of 4,8m.

When I came over together with a DNV representative, our intention was not to "solve the problem", we simply came over to collect data and suggest what they should do. And we did. We suggested they put on a 50 or 60hp engine.

They opted for a 50hp making it a light, swift, resonably priced package. A couple of months later Simon Everett (which I reckon most of you know) did a write up on it, and he found it did what it was intended to do.

The boat on the picture is a RIB636 hull fitted out by BWM ribs. It is probably the best handling offshore hull ever made on a boat of it's size.

Anyway, I did create the RIB555, RIB636, RIB 464 and RIB808 so my opinions might be sligthly biased. But, today we are working on bigger boats (7,3m+) so I do not make those boats anymore, and I do not make any profit on sales of the old models today. I am not trying to sell boats here. Just want to put the record straight.

Have fun!
Eddy

I think your slightly bending the facts yourself.

They only imported one, because it didn't perform as it should. I'm not aware of anyone working at Poole Boat Park with 15 years rib experience! They did however have a Evinrude main agent in the yard, who was given the impossible task of making it work.

Hmm, so what your saying is that George over engined the boat. So what would the max kw be on the CE plate of that particular boat? Was it not you that suggested moving the console etc?

Shame he didn't do the test when the bigger motor was on it! I went out in that boat and it wasn't fun.

Doesn't sound anything special to me for 50hp...our Ribcraft 5.3 with a Suzuki DF90 on the back has managed 3 km/litre over the entire years cruising of 500+ miles. This includes substantial runs at VMax, 60 mile round trips at 25knots+ and several hundred miles at planing speed.

Just thought I'd say...
