The pic above looks quite like the beach I have been going to for almost 60 years now. It's all sand. We motor in slow and cut off the engine at the last minute and then raise the outdrive. Jump in, grab the bow eye and pull her up onto the sand.
The stem sees no damage. The first 3 feet of the keel looks "sanded" (LOL) but it's only on the surface of the gel coat. Can't see it anyway.
When we leave I get out, push the boat into deeper water, and then climb up on the stern ladder and give her a gentle push. When she hits the deep water I drop the outdrive and motor away.
After all these years I have not damaged a boat yet.
