Just bought a Zar Mini Rib10 at the Fort Lauderdale Boat show from Inflatable Boat Pro. This is a tender for my 40' Marine Trader Sundeck. I have Kato Davits to hoist and store it. The boat is very light, about 1001bs and the main locker access is large enough for a 6 gallon tank or a smaller tank with room for safety equipment (fire extinguisher, horn, flares, etc)and there is a smaller access hatch to store the anchor/rode. It has a double floor so should keep everything dry. The boat is actually just under 10' but it appears to be large enough (Italian Design) They are supposed to deliver it to me this Friday at the boat in Marathon. Will see how it goes!
