No new posts in two days, so I'm firing one up.
We bought a new Dinghy. We had a West Marine/Zodiac RU-260 circa 2000 model. We were amazed to get a PVC dingy to last that many years. However, she was finally delaminating to the point of flooding several gallons overnight.
We ended up getting another 'Roll-up', since it works best for us. We have a 2800, so there isn't a lot of options for the dinghy. We inflate it on the foredeck and launch/retrieve over the side. We store it rolled up on the v berth (cabin sole when underway) and pass it back and forth through the forward hatch. You can really only do this with the roll-up models.
The direct replacement was the Zodiac C260
A solid seat rather than an inflatable thwart. 18" tubes rather than the smaller 14" tubes in the older boat. (The admiral is hoping for a dryer ride). fastening points for a bow bag. the slat floor is no longer 6 3" slats spaced every 8-10 inches. Now the floor slats are very wide and connect to act like an articulating, semi-solid floor. We're hoping this is more stable underfoot. Otherwise the same length and width.
We use a Honda 2HP on the old dinghy, which recommended a 2 with a max of 3hp. The new dinghy recommends a 4hp (with a max. 4HP).
So now we're deciding whether to replace the 10+ yr old rock solid Honda 2HP for a new 3.5 or 4 hp.
The old Honda is only 29lbs, a new 3.5hp will range around 41lbs, a new 4hp will be 59lbs. Trying to decide whether to double the weight for the OB and whether it's worth it.
