Question:
This will entertain you. Here was our fire drill for raising the dingy.
Jim in dingy, Diane on deck.
Jim takes dingy to side of boat and hands up loose items (fuel tank etc.) to Diane.
Diane opens stern gate and drops boarding ladder and the lifting lines. Jim takes dingy to stern and secures dingy using painter.
Jim attaches one lifting line to motor and loosens motor toggles. Diane takes up slack on motor lifting line and Jim climbs up stern ladder.
Jim hauls motor up and stores it on its stern mount.
Jim climbs down ladder and back into dingy, attaches both lifting lines and climbs back up the stern ladder. Diane pulls up ladder and closes stern gate.
Together we hoist dingy. When it catches on the lip of the transom, Jim uses the deck brush to push it off and we continue hoisting.
We tie off the hoisting lines in an elaborate cross pattern we devised.
We use heavy rubber cargo straps to further secure the dingy from side-to side movement.
This whole thing too about 10 minutes after we had done it 100 times or so.
One cheap option to davits would be a hoist arrangement using a halyard off the mast to lift the dingy and place it in a cradle on the fore deck.
We absolutely did not run the unit in oily water. This will ruin the membrane. I remember sailing along with the watermaker running and seeing an oil slick ahead. One of us would run below to turn the unit off. We didn't worry about polluted water. It is my understanding that an R/O unit will filter bacteria but not viruses. Maybe we should have been more careful, but we never had a problem. The big AC units offer UV lights to sanitize the output.
All R/O units like to be run every day. If you are going to go more than two or three days (like you are at a dock) without running the unit you have to pickle it. This involves running a chemical solution through the membrane to keep things from growing in there. When you put the unit back in service you have to flush all this stuff out.

We met a couple in Georgetown, Bahamans who decided to sail/motor their Brewer 44 directly to the Virgins. Several days out he was on watch and she below sleeping. He saw something on the aft deck that looked like oil and went out of the cockpit without securing his harness to check it out. The boat lurched and he went overboard. As he went over he screamed which woke her up. She came on deck to find him gone and nowhere in sight. She turned the boat on a reciprocal course and actually found him. Guess what the odds in that were. They were so shaken up over this that it was days before they could even relate the story on the radio.
