Equipping coastal boats for wartime supply work

How would you equip a squadron of Second World War PT boats assigned supply duties?

Favor a roomier hull and equipment suited to supply work, while deciding whether speed, gun armament or a small torpedo reserve matters most.

The supply assignment prompts a preference for roomier British dog boats. One gunboat proposal carries as many 40 mm weapons as practical and depth charges, while dispensing with torpedoes. A second approach removes equipment that does not serve self-defence and prioritizes speed, since a PT boat has little capacity for delivering supplies. Another retains two torpedoes against an unexpectedly large opponent and favors a Bofors or pom-pom gun mounting. These are competing loadouts for the scenario, with the useful payload of such small craft remaining a constraint.
