URGENT: Which 8m RIB w/Inboard diesel?????

Hi.
I am currently looking to buy a new RIB for private and commercial scubadiving here in Norway. We are lookated at the west coast and the weather can be pretty rough with the Atlatic ocean straight in.

WISHLIST:
Here are some of the spec I want
- 8m good quality RIB
- OK consolle and seating
- Inboard diesel engine (MC 1,7Dti, Volvo D3-160, or other)
- OK engine housings etc.
- OK Prices

Visited the Humber factory in January and tested a 7m Humber Ocean Pro with the Mercruiser 1,7dti engine and found this to be OK without load. Never tested it with load.

HUMBER QUOTATION:
We quoted for the 8m but were adviced to go for a larger engine like the Volvo D3-160 (160hp). The spec on this looks very good.
Humber seems to have reasonable prices on their basic boats, but as soon as you put on some equipment the price really accelrates. My impression is that they overprice most of the optional equipment.
I found the Volvo engine cheaper to buy here in Norway than at Humber. Humber said that they could deliver the boat complete without the engine, but prepared for easy engine installation here.

HUMBER OR OTHER
In a market where there are many brands and manufacturers of RIBs I find it very hard to choose. I'd like a RIB that gives me great value, quality and performance for my money. Something around 7-8,5m would be perfect. At least 30knots loaded and maybe 40unloaded (Can be w/different propeller for load/speed).
As far as I see right now the most interesting ones are HUMBER, RIBCRAFT, RIBTEC. Other suggestions?

ENGINES:
Are there any good alternatives to the lightweight engine Mercruiser 1,7tdi and the new Volvo D3 series?
- Any Experiences and suggestions?


All help, links, testrepport and experiences will be very apreciated. Maybe some of you have tried the Humber Ocean Pro, the Volvo engine or other RIBs that might be of interest - please contact me by PM or post a reply here.......


Thanks a lot
Steve M.

I realy dont think the mercruiser will do in an 8m rib.
Flat out you would be looking 26knots or around that and loaded...more like 20knots maybe less.

Volvo is a much better choice but i still dont think you would make 33knots ladden or 40 knots flat out. It wouldn't be to far off though.

Maybe have a look at the VW diesels?

I had the same experience with humber because i tried to order my diesel rib from them. The price fro the boat was great but the mark up on engine and fitting was rediculous. They were goign to charge 3 thousand pounds for the fitting. Consoles,seating etc is also very expensive from Humber.

Even saying all that i can't think of anyone who makes an 8m cheaper.

Ah, here we go http://www.parkerribs.com/
PM Andre on these forums.

I Agree (waheyy)

I'd be looking to put Two mercruisers in an 8 metre boat, I'd want to see some reilience in a cold place like Denmark and at least 250 Hp if single or 150 if twins

Approx 8m Diesel RIB

I've been going through a similar process over the last 3 months, and it came down to the Ribcraft 7.8 Offshore with the Yanmar or the Parker Rapier with the 4.2D Mercruiser (both 300HP).

Both came out at similar costs (within 2k) - assuming I paid the VAT/Duty etc - which I intend to!!

Ultimately I was more comfortable with the Yanmar as an engine choice - based on comments from other boat users and the combined knowledge of RIBnet and some of the hundreds of forums on diesel engines......one of those emotive subjects......

From my experience with Andre at Parker and Jason at Ribcraft - both top blokes who know their stuff - and they make good boats that will do what you want them to!!

I've no doubt that someone will decide I've made some bad choices - but I'm happy with my decision!!

Dylan...

P.S. Another advantage of Parker is that their lead-time is less - I believe 3 months? - Ribcraft are now on June deliveries .

8m RIB & Inboard Diesel

Thank you for informative replies.

Some thoughts:
A) Because of the inboard I thought that an 8m would be a better choice than the 7m to free som more deckspace.

B) Does the extra meter from 7m to 8m add extra engine needs in itself? The weight difference could be aprox 100kg that ain't more than one person of load. Therefore I ask myself if I need a bigger engine than the Volvo 160HP or not.

C) The Volvo 160HP have a very good torque up till 340NM wich is very good. Anyone who know how much the Yanmar 240hp have?

D) The Humber boat looked just sooooo nice and with that very nice engine housing..... smooooth. I attach an picture

Too bad I did not find this site earlier this winter so I could have some more time to discuss matters with you guys. This have been really helpfull and I have now realised that the Mercruiser 1,7 diesel is not an good alternative.

Meaning that if we go for the Humber 8m we need at least the Volvo D3-160 (160hp) or an larger engine. I do like the compact size, low weight, low fuel consumption, good torque (340Nm) and the spec of the Volvo. Both the Humber RIB and the Humber engine housing is just beautifull as well.
Would a 7 or 7.5 meter boat give us more power reserves?

But I also realised that Ribcraft is another well priced alternative, priced a bit above the Humber. Anyone who know about the quality, performance, waranty, service difference between the two companies - Humber and Ribcraft ??

Revenger?

Well, have you considered Revenger RIBs? I test drove Revenger 27 with 230 hp MerCruiser IB and the boat felt nice. Not a commercial heavy-duty machine, but for diving use might be suitable. Top speed was something around 40 kn five persons onboard.

Still, are you sure you want diesel inboard? How about outboards, much cheaper and you can get nice twin OBs with a price of diesel(s). Your combination of speed, price and size does not support diesel engines very well...anyway, I hope you find a suitable boat.

Have seen the Revengers webpage. We are looking for a bit more "workhorse/commercial" type of boat than the Revenger.

My partner has a RIB today with outboard engine. He had lots of troubles with it and will never buy an outboard again. We tend to be going far out in the ocean and do need something more reliable than a single outboard.

With fuel prices at more than 1,2 a litre and diesel @ 0,45 a litre with maybe 200 hours a year we have to take this into consideration. Second hand prices on Diesels are also better.
