Boats are measured to determine handicaps. The fastest boat in the fleet is the scratch boat and has no time allowance. All other boats have time allowance handicaps which are subtracted from the elapsed sailing time. Over the years various handicapping systems have been used including CCA, IOR, PHRF, IMS, IRC and ORR. In 2016 the Cove Island course used the ORR handicap system while the shore course used PHRF. In 2017 the shore course will start using the ORR-EZ handicap system.
