I'm sure its very regional, but here in south Florida, and just a sample size of one, SH's prices are competitive.
I considered keeping my boat in Fort Pierce municipal marina before deciding on Safe Harbor's Harborage Yacht Club in Stuart;
FP Marina fees:
$22.50/foot per month for longest terms available x 31' = $697.50
Electric @ $2/foot = $62
Mail? $5 per package if >9 per month
Pump out? $5 per
Dock box? $10 per
Clubhouse? Pool? Security? Dock carts provided? Fuel at cost? Transient complimentary? No.
Harborage Yacht Club:
$27.75/foot per month for 1 year lease x 31' = $860
Electric: included, unmetered
Mail: complementary
Pump out: free at fuel dock or in slip, unlimited
Dock box: included at every slip
Other amenities listed above? All included. Workers that call me when a strap on my bimini broke and it was flapping around, yep. Guy who comes by to ask me if he can take my trash away when I'm doing maintenance on the boat, yep. Golf cart ride from the clubhouse/car/wherever down to my boat? sure
Again, just a sample size of one, and just saying. Not sure I'm a "yottie upscale type" being a retired enlisted servicemember and a full time job holding working stiff. I just financially prioritize my boating, and pay for the privilege.
