Howdy,

Has anyone used anything similar to this? Our marina recently put in
new docks, and they're more than a foot higher than the previous ones.
My parents are getting older and can't do a high-jump to get off
their boat at low tide. It's a little 23' sailboat, without much deck
space for something permanent.

Are the docks floating, or fixed?

If the level of the tide matters (fixed docks instead of floating) then the
range the ramp would need to accomodate the entire range of tidal swings. I
would expect this to be at least a few feet and could be much more,
depending on where you are.

A short, steep ramp can be very difficult to walk! To keep the angle from
becoming too steep would require a fairly long ramp, which might not be
possible down to a 23' boat.

I would expect that any such ramp would need to be locally constructed, as
the shipping cost would be prohibitive. I would start by talking to the
marina management, if for no other reason to find out how they would feel
about mounting something like that to their docks. If they are OK with it,
they might be able to direct you to a local shop that could build something
suitable.
