Most people, especially on this forum, believe the government won't be able to kick the fiat can down the road much further, and sometime within the near future, or a couple years down the road, something like the great depression, or worse, will be repeated on a global scale. The question is, where do you want to be when this happens? Examples of what things will be like on land can be seen in Argentina or Bosnian/Serbian history. The pigeons started to disappear in Bosnia because people were eating them all.

A big factor in this decision would be, would you rather eat pigeons or fish? As for which environment is more dangerous, the sea has always been dangerous, but land will likely be much more so. Getting away from large population centers is obviously the best option. I've lived in areas where hurricanes knocked out power for a month straight, so I kind of have an idea how things will proceed when a modern society devolves in this fashion.

It's unknown whether there would be power in a prolonged financial collapse, the only thing really certain is an attempted military dictatorship that may or may not succeed, and may or may not keep the power on. When I lived in an area of America that lost power from hurricanes for a month, it really gives you a lot of perspective. There's not much to do in a situation like that except read, drink, play cards, and random physical activities that most people don't do, because they're tired from the inside of their house being 90 degrees, or it might be the opposite and be cold all the time depending on location.

Regardless, with boredom as one of the prime motivators, you start to see groups of people out and around together in the open, like it was the 1980's again, when people actually went outside. In a prolonged financial collapse, these groups of people will probably end up fighting each other for resources in some kind of tribal warfare. There's not enough pigeons for everyone to eat in densely packed areas, or even most small towns.

edit: Think I'm removing the section about giving any advice on particular boats since some people can sail a bathtub across the Atlantic, and others can sink the Titantic one mile offshore. I do have a decent amount of knowledge on what you're least likely to die in, so if you want to know that, just ask I guess.
