Own a 5 meter Tornado w/90hp 2 stroke. Prop'ed to go 35 knots w/2adults, 30 knots w/4 divers including gear. Top speed could be "Much" higher if it weren't for the gear hauling. Great as long as you don't mind being close to your buddies and not particulary comfortable for any sort of long SI. If I had it to do over, I would look for a 20-24 foot centerconsole or walkaround cuddy with a long cockpit. Alot more boat and a lot more comfortable for a day on the water. We really treat the rib as a dive assault vessel: All Kitting up on shore with the exception of pulling your sleeves on, tear *** to dive site, zip up suit, pull on harness, back role off. We usually dekit in water to easy getting back aboard. Then, tear *** to next site or back home. No lolly gagging about on the RIB it's just not very comfortable. If we're spending a half day or more out on the water, with lunch during the SI, or anyone that's interested in getting some sun, etc. Then, we look for one of our friends 20-24 footers.
