I don't know what remote islands nor your cargo contents, but here in Fla and the Bahamas, the shallow water extends out from the dry land several feet. This situation would be undesirable for an inboard configuration. An outboard can be pushed out from the bar coupled with engine tilting helps getting back into deeper water easy [img]/images/graemlins/smile.gif[/img]
Most inboards I see doing the island hoping deal, anchor out in 3' or so water and wade to shore. As mentioned before, I would not want to see your rudder mud stuck and have it sucked into your cooling system [img]/images/graemlins/shocked.gif[/img]
Here is a picture of my boat nosed up to an island. I still climb off the transom with a ladder and wade to shore.
