Just to alert you to a demographic who might not be aware of OpenROV. Cruising yachts need to anchor in water deeper than they can see. In the Pacific, the anchorages are particularly deep, and there are often stray coral bommies around which your anchor can become tangled, sometimes making it impossible to lift it.
It is also worrying if you are at anchor at night, and the wind gets up and risks blowing your boat onto a reef. It is reassuring to know whether your anchor is securely set into the sea-floor.
An OpenROV will be a huge boon for cruisers like us. We will be able to anchor in deeper water, away from coral, and inspect the anchor to ensure it is safe, or check how it is tangled and how best to untangle it.
