One other point to add to cam's good summary.
You should avoid tying things to the stanchions.
This is good advice. I tend to forgot that having welded 1 1/2" Schedule 40 pipe for rails instead of lifelines allows me to do things that would be half arsed on the more typical boat.
I should have qualified this by saying that the Portabote would be laid down flat on deck at the first sign of weather. My foredeck is broad enough to do this and not have it restrict movement much.
In a perfect world, I would love to retube my Zodiac RIB in Hypalon (it's PVC and fading fast), but everything aboard is predicated on the strength and physics of my 110-lb. wife and young son being able to physically move everything aboard. Getting the RIB on and off the deck using a halyard (and over those high rails) simply didn't seem feasible for her to handle solo, whereas she can handle the other, lighter, less wind-catching tenders capably.
Moving a 9.9 HP out of the forepeak (I don't like them on the rail) would be even harder.
