This thread is kinda interesting...kinda. A boat for it's intended purpose and it's all relative and a da dada da...
Sea- a place outside of the bays and ICW
and off coast.
Worthy- can preform it's function there.
There... its not that relative and intended purpose is pretty exact. If it can sail safety
, consistently off shore it is seaworthy.
I got a cruiser that had already circumnavigated. It had come back after crossing the oceans. If you can do that with your Catalina
22 pop top/MacGregor 26 hybrid then it is seaworthy.
Or at least you are.
