For boat selection. a collider should be appropriately sized and located on the prefab and placed on layer 9 (Content).
To allow selection of resources on the boat, the collider should avoid overlapping the resource storage location(s).

Boat Creation and Harbours

Note new boats will need an entry in a Boatyard's "supportedBoatTypes" to allow construction, unless a new building can create the boat instead.
To dock at a harbour-type building, new boats will need an entry in harbour's "supportedBoatTypeHash" under "BuildingPortDataInfo".
To enable a new boat for an expedition, the harbour ID(s) will need an entry in the boats' "validExpeditionBuildingHash".
