size matters

Hi All,
my first posting so please don't shoot me down in flames!!

I'm planning on buying a RIB (on a commercial basis) to take 8 divers. I'm thinking about a 7 - 7.5m RIB Craft with a Mariner 225 Optimax. Thoughts/views/comments please.

Regards,

Mike

Ribcraft are very solid boats and should be ideal for what you are looking for. Can't fault the Optimax either, I've got one on order.

Have a look at this 6.8 Ribcraft with 225 Mariner Opti, just what you're looking for.

http://www.buyaboat.co.uk/boatdetail...srefno=1989001

This one is just down the road from me, don't know if you want to travel this far but its a lovely rig.

If it were me I'd go for a tornado, especially for diving as they have high lift hulls and I know of a lot of dive clubs who swear by them. This one below is a beauty. 7.5m Tornado with a 225 Optimax and 2 many extras to list!!! Laurence Lock the sales guy knows his stuff about rigging dive boats and I'm sure he will fit anything you want (bottle racks, boarding ladders, etc.)

Nice bit of advertising there Riva, you wouldn't happen to work for ribs for Sale would you ?

Not sure how well a 7m rib with 8 people on board is going to go with 120 hp, but could be proved wrong.

There is an 8.5 m Prosport about somewhere with a 225 opti at 21k.

So Riva, you are recommending a 7m rib with a Vauxhaul astra engine as being perfect as a dive boat for 8 divers are you ?

May I enquire why you think this boat will take 8 fully equipped UK divers and what sort of speed it will do with 120 hp ?

Past experience of an 8m ribcraft showed a Yam 240hp engine only managed 20 knots with 8 divers.

Jolly helpful. Not.

Well I'm sure those pictures, luverly as they are, will be of bugger all use to Firkin Diver in his pursuit of a dive rib!

< Edit -- I moved them to a new thread JK >

In an effort to get back on topic....

FD,

Suggest you read the some of the posts on the commercial forum. Sounds like with the fuel tax reclaim petrol outboard is the way to go so you are on the right track!

Ignore all second hand ready fitted boats with lots of nice seats. What you need (of course you know this) is lots of nice deck space, bottle racks and nice comfy tubes for divers to sit on.

7.8m Ribcraft supposed to be good boat. Garygee has one (albeit diesel) so he can comment. Imagine it would be good teamed up with 225 Opti or larger. (Theres the whole 2 vs 4 stroke debate to be had of course.)

Other thoughts might be a big 'umber (8m?), Tornado, mebbe an Osprey or one of those nice Polish BW...sorry Parker 7.5ms! Or if you are well wadded up and want your customers to experience the best a 7.5-8.5 Scorp!

Probably would go for a major make and avoid some of the ahem, more leisure orientated budget ribs so that it stands up to the commercial use.

Cheers,
Alan.

EDIT Ooh, just noticed that I now appear to talk sense as well as being a salty old seadog. Thanks JK!

Mike as someone who has done a fair bit of diving from Ribs & Hard Boats
I will give you my 2-penny’s worth!
You will want a seat but the divers want deck space & are happy on the tubes when under way, the more spaces the happier the divers. I have never liked bottle rack as they take up space & do not always fit the bottles being used, twin sets etc. but I know some people like them!
As for engine clean burning outboard nothing as bad as kitting up with diesel fumes filling up your lunges or smell old two strokes!
Stability you want something that is stable at rest when the divers are kitting up!
As for size the length is no good if it is some sleek pointy things, you kneed width as well!
For instance I have an Osprey Viper 5.75 with 100hp this is not the longest boat but it copes well with 6 divers + skipper with second cylinders on board. I t has coped with 8 divers but this gets a bit cosy.
Hope this of some help.
Regards
Nick

Hi Mike

As a diver and diving instructor, I can only agree 100% with Nick

I have a Osprey Viper 5.95, and I have observed the same things as Nick. Go with deck space, width, and the tubes need to rest in the water when the boat is not moving. Go for a bottle rack or don't dosn't matter.

Just my thoughts
Rene
