Good Points. on boat dragging water when healing over ( unless you have a very small RIB) with a Weaver type set up, not a problem with Power Boat...
Also I'm bow in at Cooper River Marina.. wind up my stern's a$$, waves breaking over stern rub rail... I don't need a stern sail and any water hitting a RIB. Turning on propane, accessing storage in stern is very restricted. And again, taking off and on a 90Lbs motor is no fun...... not really doable w/o a winch of sorts....
Some sort of Davit system seems best.... there are several good choices. Ocean Marine may be the best option for an off the shelf system, designed for Hunters over a decade ago.... Not the heaviest duty, maybe not the cheapest, although all of them when I looked ended up at the same price or more, by the time you add in the "extras".
We have people questioning the strength of their stern rail for holding the engine.... yet 200 +lb people are in the seats connected to that same stern rail... maybe several....
The Ocean Marine added yes about 8 screw holes to by stern area.... Less than the mounts for a cooler bracket on my fore deck.
