Blyden Terminal IS the defacto "Tortola Visitor Transportation Hub". The major challenge on the STT side is the airport and ferry terminal taxi associations but I believe a bit of negotiation could eliminate that.
My proposal does not eliminate the existing ferry operators but presents a way for them to work together to finance a new fleet, reduce shore side fixed cost and boat operating costs, increase reservation rates and provide reliable convenient schedules. Everyone wins if a few people would just take their heads out of the sand and cooperate with each other.
