Trueblue, that was one of their motivations: eliminate the cash on both ends of the transaction.
I see a lot of positives. Moorseacure knows what their tackle is designed to handle. If the captain has to say what kind of boat is reserving, then the app can decline a reservation from a boat which doesn’t conform, thus protecting Moorseacure’s property.
If heavier moorings, separated further apart are needed, then Boaty Ball can charge accordingly. Why should a 38’ mono pay the same as a 65’ cat, when far more of the former can be accommodated?
There can also be high and low season rates, or different rates for different days of the week.
