I dont know of any
charter companies per se in either country. The only active charter market in
Panama is in the San Blas and there are a LOT of substandard opetators in that market (all just individual boats/captains, mostly in the backpacker segment, most operating illegally).
You might try San Blas Sailing, not really a charter company, but more of an agent/broker. They are one the more reputable agents in that sleezy market.
No bare
boat charters in that market...or anywhere in either country I know of.
Vet your boat/captain VERY carefully.
