What Shaktigurl said about boat owners installing their own gear
at their own expense is correct, so just grabing an empty mooring will not be met kindly by returning owners. We are currently out cruising and expect our mooring to be open when we arrive. She is also correct that the owners in the field watch over their neighbors gear
while they are away. That said its easy to install your own mooring if you dive. If not Zack at Eastern Marine
Services will gladly install one designed for your boat, he does great work and can be reached at (561) 744-2242. There are several parks in the South Lake Worth mooring field where people anchor
their dingys for free as well but it can be a real hassel to find parking nearby and to get to your dinghy if you anchored it at low tide and come back at high, i.e. Your going to get wet. The palm beach sailing club is a good compromise between cost and convience.
