As far as pirates swarming coastal areas, one, they suck gasoline and that won't be available, and two, coastal areas are easy to avoid. The open ocean is where you go to sit out crunch time and await events. I have spent 60 days at sea (Guam-California) and could go 200 days if I needed to, say, during a pandemic.
These are my escape pod.
Many of us here know your life quite well, it may be hard for some newcomers to understand your passion for the sea and your knowledge of survival skills.
Maybe they should read some books? (wink wink)
I however have found a natural barrier against zombies, illegal aliens, man hungry cell phone deprived blond bimbos or any type of urbam refugee good and bad and thats living in Alaska, its pretty darn difficult to get to in short order.
Even just driving here can be an ordeal and the road can be closed and guarded immediately and held with just a couple of people. Of course we will probably have Anchorage zombies but as soon as they try to raise a ruckus the rednecks and Valley trash will have a field day.
Ideally a person who needs to stay on land should find a geographical area thats either unattractive to urban zombies and such or easily defendable or remote.
But overall the smart move is to simply run away and don’t look back, flee the cities.
If we have major catastrophic disasters such as mega earthquakes, tsunamis, polar shifts etc. I am thinking that running to the hills is still the most traditional and safest bet.
Urban zombies cannot survive in the mountains.
I assume you have a way to desalinate water? Solar?
