We live aboard on the South Coast of the UK. 5 years ago we got hold of some "Fladen Rescue
Suits". These are one piece suits that are very well insulated (5mm closed cell foam). They also have around 80 Newtons of buoyancy built in. They are totally warm, comfortable, water
proof and dry fast. In addition to all of this they cost less than £100 each.
As for boots, Timberland make their ankle boots in wide sizes, have non-marking soles, are non slip and better looking that any of the so called sailing boots. Currently I am wearing a pair of the Caterpillar work boots, Great, warm, dry feet at a price
I don't have to care about.
The fishermen know what works at a reasonable price, the Fladen Rescue
Suits are built and priced for fishermen.
