I'd looked at the Portabote about 3 months ago
I really didn't want to tow anything, and there sure isn't enough deck area to stow a boat, so this became the leading candidate. I was thinking the side of the cockpit lashed to the lifelines was the right place. Out of the way if you need to get to the foredeck. And it rows well (according to them).
But 50 lbs will get heavy if you are lifting it up on deck every few days. And if it takes 30 minutes to break it down and set it up, there will be a lot less trips to shore if the boat isn't ready to go.
As of today, I'm back looking for a very small inflatable. I had a small one before that sat on the stern pulpit rail, sideways. Blocked all views aft, but it was fast to launch.
