There are a total of 30 Submarine Parts to collect in GTA V.
It doesn't matter which character you use to collect them. You can purchase
the Sonar Collections Dock with either character, but only Micheal
can initiate the quest. It will be available to purchase once you unlock Trevor in the main story. The property is in the Northwest part of the map and costs $250,000. A Dinghy and the Yellow Submarine will spawn there once the property is owned.
After purchasing the Docks, a new mission appears for Micheal called, "Death at Sea"
. You will meet a lady that goes by the name of Abigail, who wants to solve the mystery of her husbands death for an insurance company.
Beware of SHARKS!
Stay alert underwater as you will run into lots of them. Always keep your dinghy nearby in case you have to quickly get back to it.
