Soldered joints are continuous metal as the solder does more than just stick to the copper -- it dissolves into it. There is no metal to metal just touching where salt water can get in and create galvanic chemical action -- corrosion and poor connectivity in time which is a reliability issue.
A soldered joint lasts. I like it so much, I tend to avoid crimp on terminals unless there is a very good reason to have them. Instead, I even remove the screws from switches and put the bare wire through the hole and solder the wire directly onto the back of the switch.
Platt electric has self-vulcanizing rubber splice tape. Buy 63/37 solder. That's 63% Tin 37% Lead. Soldering is easy. Practice a little and you will do well. Stagger all connections to make the splice thin and longer and not have soldered joints adjacent to each other. This is greater separation. It's important to have clean copper surfaces. You can use ScotchBrite or chemical flux containing zinc chloride. Don't use paste flux. Get liquid flux because it rinses off completely to remove the chemicals. Dry the wires and stretch the rubber self-vulcanizing tape and it sticks to itself and seals the wires tight.
