eFoil regulations & spots in Cayman Islands
eFoils aren't named; Cayman treats them like jet skis under the Port Regulations and Marine Parks Regulations: free private licence, PFD worn, under-15s supervised, 5 knots within 200 yards of shore outside designated watersports areas, no swim-zone entry, 5 mph in Environmental Zones.
Regulatory overview
The Cayman Islands do not mention eFoils in law. Motorised craft are regulated by the Port Authority of the Cayman Islands under the Port Authority Act and Port Regulations (2017 Revision), which govern licensing, speed, swim areas and safety equipment for all "vessels" and "power boats", while the Department of Environment (DoE) enforces the National Conservation Act and the Marine Parks Regulations (expanded in 2021). Jet skis and wave-runners are named in the Port Regulations, and an eFoil is in practice treated as a small power boat under the same rules.
Local vessels must hold an annual Port Authority licence; jet skis used privately are licensed free of charge (commercial jet skis pay CI$150) and boats of 21 ft or under also pay nothing. No operator licence is required, but regulation 31(2) bars anyone under 15 from driving a power boat except under the control of an older person. Regulation 84 requires the operator of a jet ski or wave-runner to wear a life preserver, and vessels of 8-20 ft must carry one for every person on board. Insurance is not legally required. Rental operators may only let craft to people equipped with an approved life jacket.
Outside the buoyed watersports areas listed in Schedule 8 (South Sound, Frank Sound, East Point, Colliers Cay, Rum Point, Water Point at Public Beach, Duck Pond Bight and part of Cayman Brac), no vessel may exceed 5 knots within 200 yards of the shoreline or travel parallel to the shore within 50 yards. Vessels must slow to 3 knots within 200 yards of a divers-down flag, 5 knots within 50 yards of an anchored vessel, and may not enter marked swim areas, most of which line Seven Mile Beach. Marine park Environmental Zones are limited to 5 mph with no in-water activities; Wildlife Interaction Zones such as the Stingray City sandbar prohibit anchoring in under 3 ft of water; and jet skis are excluded from the northern zone of Barkers National Park.
The Port Authority, police and DoE enforce these rules; Marine Conservation offences carry fines up to CI$500,000, a year's imprisonment or both, with boat confiscation. Rules apply across Grand Cayman, Cayman Brac and Little Cayman, with Public Beach on Seven Mile Beach the focus of jet-ski crowding complaints. Ride inside a designated watersports area or through a licensed operator, keep the DoE marine-parks app open for zone boundaries, and ask the Port Authority licensing office whether a private eFoil needs a vessel licence before launching.
