Advice needed on a new RIB for tourism in Brazil

I would like to begin by saying how much I enjoy your forum. Wisdom combined with wit make for an enjoyable learning experience. I am starting an ecotourism business just outside of Rio de Janeiro and would greatly appreciate any help or advice offered. I am more or less forced to go with a Brazilian manufacturer of RIBs because of lack of vendor support for imports. They seem to make a decent quality boat on the surface (no pun intended), and they offer a seating configuration unlike any I've seen from another maker. If anyone is interested in offering some feedback, they have an English version website since they're starting to export to the U.S. The model I am most interested in is the SR-760, 22 person diesel sterndrive version, unless someone has a compelling arguement to go with petrol sterndrive or twin OB's (not intended to start another forum sh**storm).

Their main site is:
www.flexboat.com.br

and the page that links page to all the versions is:
http://www.americanflexboat.com/pro...sr760models.htm

They will put in a Volvo or a Yanmar, but service here is better and more widespread for Mercury. If I can sell enough blood, I'd probably opt for the cummins mercruiser 4.2L D-Tronic 250hp (225@prop) with a Bravo 3 leg, and possibly an auxilliary outboard (will always be close to shore with other boats nearby). Since I'll be hauling around an average of 3000 lbs. worth of tourists 3 or 4 times a day, my main concerns are low-end torque for faster planing under load and fuel economy. Average cruising speed will be about 28 mph with not much need for higher speeds or WOT (unless I'm trying to impress a string-bikini-wearing Brazilian nubile). Also, diesel prices are roughly 65% of petrol prices, and petrol quality can be circumspect down here.
The price of this configuration, fully rigged without the motor, is 31,000 USD. The list price for the 4.2 D-Tronic here is 36,000 USD, so I'll be trying to import a new one or find a good quality used unit. They'll install any motor I send to them with no additional labor charges.

The basic route will include calm water, open ocean, maneuvering through sea caves and rock formations, and whale/dolphin/turtle watching, depending on the season. And a few beach stops for swimming.

Any comments or suggestions, negative or positive, will be greatly appreciated. I hope to be a regular in these forums and one day hope to understand half as much as most of you know about Ribbing.

Thanks in advance, RD

Free rides for any and all who can make it down here!

Am I to understand correctly that this is a 25 ft boat (7.6 mtrs) and it takes 22 people seating plus the skipper? What is the beam?

Have a look at the website Manos. They really do fit 22 seats into a 7.6m rib.
Only with outboards though, it's be more like 16 wiht an inboard.

These guys will even make a flybridge 7.6m rib!

I looked this is why I'm asking. It seems impossible to me unless the beam is near to 3.5-4 mtrs

If you look at the CE plate on the back of your rib you will find it's rated for al lot more people than one would want to put on it. I think they do it on weight. My Avon 8.4 is rate dfor 24 and my 4.7 was rated for 7 ( which beggars belief!)

Robbie I do have a concern about the number of people you are carrying , the performance of the engine is going to be compromised somewhat so you might hve to keep the hammer down to maintain an average speed. This might compromise your wave riding technique.

Also the most charter guests I have had on a rib was 12 and that was very difficult to keep track of how they were doing in terms of safety and comfort if you have more than that on board you are definitely going to need a crew member to help with this task.

The rear driving position is a must for that many people as is diesel power for operating economy but can you get a bigger one as I thing it's going to be a bit chuggy.

another thing I would want to check out is what the ride is like for the front apssengers.

All in all it looks like a wonderful venture and I wish you the best of luck

It depends if is Cat C or Cat B or Cat A.

For 5 mtr RIB Cat C the (Watercraft 5mtr) the max persons permited onboard are 10 for a Cat B and Cat A the max persons permited on board are 6. I know I've got one

When I was down in Rio we got the local Volvo guy to rebuild the Ships FRC.
Crew said it was fine always started and went out - sometimes came back!!!!!!!!!!

That was a Huricane with a volvo leg etc. He was able to rebuild it about 2-3 days from being called in. Sorry no name but he was the local guy.
Hope it helps
James

Still don't think so, seating looks very crampt to me, no grab rails to hold from for the front passengers, I don't think that there are any grab rails for any actually, but if they run it good luck to them.
Where I operate my RIBs this boat as is, would never got a commercial licence.
