To me the number one concern on a dingy for a CD 22 is its being light enough to easily take off & on the boat cabin roof or have the ability to safely tow. If its to heavy for that or has to be brought out of storage for deployment it's likely going to stay on top & many enjoyable trips to shore will be missed with its use pretty much limited to the very unlikely need as a life raft. During our 2003 & 2004 Alaska cruises we had the West Marine RU260 & it only came off the boat one time & that was at Red Bluff Bay. Even though it weighs only about 50 Pounds its shape makes it very cumbersome & difficult to deploy & return by myself causing in my opinion the time & effort to deploy & return not worth the enjoyment of use. Jolee can't help due to severe shoulder injuries, so we found it much easier to just take the CD22 to shore even with the tides & other hazards evolved, though there are many instances where that just can't be done, so I know during that period we missed out on some additional enjoyable experiences. Sense we started towing the Mokai with its simplicity & ease of use from the boat, we haven't beached the boat from the ocean again except for letting it settle on a good bottom from a shallow anchorage during a low tide. The Mokai motorized kayak for our desired style of cruising turned out to be the best dingy possible.
