And it is even easier from the water with a solid platform to pull/push on


Fit females can do the same thing, with style:

If sailing two up, one just walks up the hull while righting. Then helps the partner up. Best and safest if both are able to boost themselves up. My favourite spot to enter the boat from the water is at the intersection between mainbeam and hull. Nice triangle to pull/push on and no scratches/holes on the boat. Also a place very close to you after righting the boat.
