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:
and the page that links page to all the versions is:
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
