Hello all

I own a 17ft half cabin boat which weighs around 800kg. I currently have a
traditional sand anchor (sized correctly for the boat) with around 2
meters
of light chain attached to it.
I anchor the boat on in an area of beach type sand, trying to always let
out
about 5 times as much rope as the water is deep. On all but calm
conditions
the anchor will drag, even after diving down and digging it in by hand. I
am
considering buying a plough anchor in the hope of superior holding power.
I
have been told the sand anchor should be as good as any in sand and
perhaps
a heavier chain would help.
Any thoughts or experiences with different anchor types would be greatly
appreciated.

Daryl




I think the ratings for anchors to the size of the boat are generous. Go to
a bigger anchor. A sand anchor is probably a Danforth and I have had the
anchor rated for my size boat, just plow through the sand. Go up a size and
try it. Borrow one from a friend.
