Julian,
I was, I've hung my helmet up now! not in rib though, I had a brief spell in class 1, a season in class 3 six litre in the UAE and 3 years in NPC 2/touring class over here,
most other involvement with racing was as an engineer working for other teams

Julian,
I have to be honest, no, I have a sportsboat for pleasure and do loads of cruising with that, I'm on the forum coz it's a bit of fun hearing all the different points of view, and occasionly sticking my oar in

It's funny you should say that, JK and I discussed that very subject in email just recently! I have a Phantom 28 rigged for fast, cheap(I'm very mean) cruising, poker running etc.

How fast is your 8.5 with the yanmar? (no jackanory's please)

and which drive have you got?

Speed

Phatom 28 is a nice boat. What size engine do you have.

Our boat does 49 knots with a full tank of diesel. Had 51 out of her once but that was with a light load. We have a bravo 3 leg on her. The leg blew up after 80 odd hours and we had it rebuilt using stronger components and so far have had no problems. Now done 430 hours.

It a great cruising rib, very comfortable even in the rough. Been in a force 9 with her and no problems etc.

Julian

Mr Priddy

Your not wrong there Alan. There were several worrying moments on that run, like being hit from behind by a big wave which was nice. But i'm still here so it ended well.

There was a Phantom 28 for sale last year with a 345hp diesel and surface drive IIRC. Looked like a good fast economical boat (of course albeit not as seaworthy as a RIB ). Is that your boat?

On the performance question I am convinced personally that outboards are the way to go for smaller (say 7.5 and less) RIBS where useage is around 100hrs per season. Arguably outboards are better suited for purpose than heavy diesel engines in relative light RIBS (hence mounts cracking etc) and overstressed drives - Bravo 3/3x/Yanmar 300 failures being the case in point.
Fuel availability can be an issue but most RIBS of this size live on trailers and can hence be refuelled at Tesco's.

Bigger RIBS its a different matter. If you need to refuel alongside and do extended cruising then diesel is preferable. I do not believe however that a truly great engine and drive combination exists for the 8m+ RIB. Upto 250hp (Yanmar 250/Bravo or Yamaha 240/Hydradrive) but over 300hp?

For Seahound the choice is clear - same engines and outrageous fuel bills. New outboards at some cost and much reduced fuel bills (probably in the order of 40%+ compared to race tuned engines?) or effectively selling the boat and buying another one with diesel engines!

All IMHO, FWIW etc etc.

Alan

Julian,
sounds cool, who's beefed up bravo bit's did you use?

someone on this thread talked about using a 420 yanmar in seahound (in fact I think they were talking about a pair) not sure that person realises the size and wieght of the 5.7litre yanmar, even on a Bmax drive, which is the only drive with an internal gearbox that I know of that could take that power at those rpm's would be a bit heavy and very pricey! maybe 30Kish, lot of dogh for a single!

My boat has twin GM 6.5 V8 TD's through bravo 1's 325hp or as crazyhorse calls them, old tech third party marinized crap, maybe we'll revisit this when his electronics are 5 years old and had a swimming lesson or two, and as he's only got one it'll be a good book for a week or so while the seagull putts away merrily getting him back to the volvo agent
