ais
Ais is one of the best tools to have on any vessel small or big
Insteed of say hay you or the boat at this position the knowing of there name and being able to talk directly to them in traffic is great it also helps to be able to look ahead for meeting in tight spots
The info that is regularly changed depends on the master or mate and the unit you have some are easy and have more info on them some are hard to imput and have little info but all in all ais even on a small sail boat is the best thing to have
The need to know information on a meeting vessel is important if he is forein or a tug or a ship being able to know his attitude gives you a better understanding of what he is going to do in a turn for example if he is going to slow are you going to suck him over to you some of the best ais give you CPA these are the best well hope that help ...,,,??
