There have been times when the car park was full and it was difficult to find a space. This can be particularly bad when a lot of boats are out of the water and the car park turns into a boat park.
The new scheme is clearly intended to support the boat owners and encourage everyone else to park elsewhere. Each berth holder gets 2 free parking spaces, and 3 half-price parking spaces. Some berth holders live on their boats so any vehicles they have are taking up long term parking spaces.
Whilst their tenants (the other businesses) may seek concessions I'm not overly optimistic much will change.
