Boarding ladders
I have two boats a Windjammer 21 and a Embroden 32. The Windjammer 21 name is First Born and she sports a stern extend able s/s stern ladder which when fully extended goes 4' into the water. On My Embroden 32, which is named Teacher's Pet III, I have a fixable s/s ladder which hooks on to two mounts on the side rail of the boat, I have them on port and stbd sides, My dinghy is a 14' nester with a well covered rub rail. I tie the dinghy fore and aft, snugly against the side of the hull, and can locate the seat we step on right at the ladder. This ladder extends down into the water about 3'6" just enough to be able to climb aboard with diving gear on, less fins.
I feel that a boarding ladder must really be a boarding ladder, whether U are climbing out of a dink or coming out of the water. Both mine are stainless steel, one folds the other I tgie off on the stern rail when its not in use. Whenever the boat is at anchor, I always tie off a float alongside the ladder; we have cats and on one or more occasions they have gone overboard, the float has saved their lives. Something to think about with dogs too.
I normally post on the trailersailors board so I do not know how to post pictures here?
