Base model:
***Anytime the Bank account is updated, the Net Worth need to be updated.***
Net Worth $$ =
Bank account $ + (# of ships x Ship Salvage Value $)
When buying a new ship, the fisher pays full price of the new ship.
When selling a ship, the fisher gets the salvage value for that ship.
When buying a new ship, the fisher pays full price of the new ship. Unfortunately the value depreciates right away for the ship's salvage value.
The Computer has a Player with 2 ships that are also moving and catching fish.
