I capsized the Duo dinghy in a controlled test a couple of years ago. Here you see me capsizing it, righting it and then sailing away. You can see it is very stable, the tubes add a huge amount if extra stability and act as fenders when coming alongside, yet are not in the water in normal use. The Duo is a 2 sheet plywood dinghy that was built in 2 days. It can be rowed, sailed or motored. A nesting option is available. You can buy plans and see more details here http://sailingcatamarans.com/index.php/designs-2/46-beach-cats-and-dinghies/420-duo-10ft-sailrow-dinghy (this video has no audio)

While crossing the Mona Passage, 35 nautical miles offshore, we ran into trouble with our Yanmar 4JH4E. We were motoring in light winds when we noticed a change in the exhaust pitch — turns out, seawater wasn’t flowing properly. We checked the impeller and, strangely, it looked intact… but it could spin freely by hand — not a good sign. After getting towed back to our anchorage at midnight (huge thanks to Michael, who came out and saved us!), we dug deeper and discovered that the gear inside the old water pump had worn down badly. It turns out the pump wasn’t making full contact with the internal gear, likely due to an aftermarket impeller and shallow gear engagement. We ordered a new OEM water pump from R&B Power in San Juan, and they were awesome — super responsive and got us the part
