^^It's likely that they would not be willing to drop off. They would have to enter Nicaragua
, with all the official paperwork and expense that that involves (been there; done that: either adjacent country: Costa Rica
are far easier. Guat's a bit of a detour up the Gulf of Fonseca).
Any detour is going to take time: turning aside, checking in, checking out, resting perhaps, waiting for weather
. I'm not saying it's impossible for it to happen: I've hitched rides on sailboats all over the place, but the first rule
of hitching is that you must be flexible, and enterprising, and willing to take what's available and work
with it. that may mean bussing from Panama to Nicaragua, or from Costa Rica
, or biding your time in southern Mexico
until a boatload of surfers rolls by.
