We use this technique when I go out grouper fishing with a friend in the Gulf of Mexico. We regularly
anchor in 100+ feet of water. Obviously its a drag to pull the
anchor to move to a new spot, and he likes to move often. We deploy the bouy, then power off at about 180 degrees from our
anchor course. Since the bouy is so large (12" or more in diameter) the water provides enough resistance to force the bouy down the
line and lift the
anchor. I should point out he has a power boat, we usually power quite fast (8-10 knots or more) to raise the
anchor, and the
anchor is a light
danforth type. Since we are just anchoring for a few minutes at a time there is no need for a heavy
anchor or much chain. I should also mention that the
anchor comes up mangled on occasion.
If you have a sailboat (limited speed under power), use a reletively heavy
anchor, have a length of chain approaching the depth of the anchorage,
anchor in fairly shallow water (under 30 feet), or don''t want to bend your
anchor with your engine''s hp, I suspect you would not benefit from this device.
By the way, his is homemade as suggested above and works great in our application.
