You can't actually say that inherently a longer boat is a safer boat. There are a lot of factors having to do with the boat's construction. I mean the vessel's construction.
Every Maritimer in Canada will be saying, “She calls it a boat”.
It has to do with the vessel's construction, how it's used, how many crew you have, and the rest of it.
Certainly there is a perception that on average a longer boat is likely to be larger, heavier, and, if properly crewed, on average likely safer. One cannot say that, because it depends a great deal on whether people have made amendments and modifications to vessels and have had their vessel stability assessed. There are a lot of vessel construction considerations to determine what actually is the safest vessel.
