Make sure you get a ladder with enough steps. The one on my 19' runabout has
one step and the platform: the step is only about 1' below the water surface
when in use. While my feet can't go under the boat, as on your rope ladder,
it's natural for those of us with a belly or lack of flexibility to lean
backwards while getting a foot on that step, requiring a lot of upper body
strength to get up and forward. At least one more step in the water would be
a big help.

My sailboat is an 18.5 foot Sandpiper. I ordered a hinged stainless

steel
boarding ladder that I will bolt through the transom. When underway,

the
four steps hinge up and can be fastened to the stern rail.



Well...I have to figure something out, even if it involves heavily

modifying
a boarding ladder. We're missing out on some good swimming opportunities.

Say there's a small, open, no frills, 12 or 13 foot boat with an outboard
motor. In the boat are two adults and their ten year-old son. Assume that
the boat is sitting stationary in relatively calm waters (bay or harbor),
and that there's no water inside the boat. How likely is it that the three
of them might capsize it if they were to all simultaneously put a foot up on
the same side of the hull with most of their weight? Maybe they were all
reaching out for something. Would they flip the whole thing over and get
dumped in the water? Is that conceivable? Likely? Doubtful?
Any thoughts welcome.


Interesting question.

The answer that comes to mind is probably not. The instinctive
reaction to rolling a boat over is to lean away from the direction of
the tilt. However, it would be possible to fall out of the boat
without the boat flipping over due to instability. And, just for the
record, if they were all drunk, or fooling around, it probably could
be done, but just stepping on the gunwale it's unlikely.

I have a small '87 12 foot Starcraft that is very tippy and I'm a big
guy, but I've never even come close to rolling it over even being
stupid by leaning out of it to land a fish.

Thanks to everyone for all of your replies. This is very good information.
It sounds like my little family will be spared the inconvenience of having
to try to right their boat, but I have a sneaking suspicion that one or two
of them will wind up taking an involuntary swim anyway. I'll have to work
on it.
Thanks again.

I agree. Unless they're trying really hard to flip the boat, they'd
probably just dip the gunwale under and at worst swamp themselves.

Been around boats for 45 years. Owned some small ones.

I'd say "likely". Especially if it were a light weight aluminum hull.
They'd get rather "tippy" with this relatively heavy load and I'd
guess if it had little freeboard, that one side would take on water. Once
that starts happening, it's an additive effect and the boat would more
likely swamp from the side rather than turn over 180 degrees.

No matter what happened, it would be the husband's fault.
