Remember two boats have been lost doing transatlantic this year, one at least looks like it was hit by a ship. You really need AIS its the only thing that can show ships where you are as opposed to showing only you where ships are.
Unless the ship/ boat is a fishing vessel in which case it doesn't carry AIS . I think the radar and AIS are equally important.
Comming into NY Harbor at night last year about 25 ships showed up on AIS while there were 45 others with additional radar signatures. Just going on the AIS would have been useless and / or more dangerous.
