Harbor/coastal traffic, shallow or obstructed water and powered-craft restrictions are not addressed in the post. The rider specifically does not recommend the area for downwind or SUP-foil learning.
Parking & access
The forum names Sand Island but gives no lot, rigging area, legal water entry or powered-craft rule. Verify current access and efoil permission before launching.
“A Progression Project forum Oʻahu rider reports practicing on an efoil at Sand Island. The rider explicitly says it does not appear to be a good downwind or SUP-learning location, so the record is limited to first-hand powered-foil practice evidence.”
