For what it's worth, I copied what Yellowstone John did on Farwest II, and that is to install a removable 3-step dive ladder. The mounting block goes smack in the middle of the accent stripe just aft of where the back of the cabin meets the gunwale; and the block is not as ugly as one might think. The beauty of this is that, when climbing back aboard, one can use the hand hold on the back of the cabin. Also, one is not dodging all that stuff in the motor well. Speaking of which, the ladder, when removed, stores beautifully in the motor well. I put a SS backer plate on the mounting block and the whole deal is very solid with, as John said, no oil-canning whatsoever.
