Welcome to the store.
If you come here for advice on which trawler to buy, you will get lots of advice.
Establish an initial budget for buying then realize even the perfect boat will need 'improvements', to make the boat 'yours'. That too is expensive, figure $50K to $100K.
Please dont even consider a "fixer upper." You will spend all your time and money doing the 'fixer upper' part.
The meek will inherit the earth but, the brave will inherit the seas.
