I only have a second but saw this and had to reply:
A parrott is NOT a good partner for cruising. If you are going to stay in the US and have an implant, you will probably be ok. But try going into some of the south islands, etc and you may very well find yourself denied entry. Parrotts are one of THE MOST illegally trafficed animals in the world. Unbelievable red tape for entry and exit with those birds.
It is not the boat that is the problem, it is the governments of other countries - especially where these birds are native and are being stolen and sold on the black market. Not to mention, you might just come back and find tweety's cage open and heading out to some shop somewhere.
All I am saying is that you need to check your destination. It is not like here in the US where these birds are not native and can be bought at any local bird store.
Just FYI. US, it is ok. Outside, you better check FIRST! Here is just one quick example I threw out.
