Compute your Anchor Weight here. This is no substitute for good judgement and seamanship but merely an aid to give you an idea which anchor weight to use, based on your boat weight.
Please use your own value here for displacement weight (kg):
Minimum Anchor

This Anchor weight calculator should not be misused.  Remember that an anchor or grapnel has different characteristics with different types of seabed types and surface conditions like gale winds and currents.  An anchor should consist of a length of chain from the anchor to make the anchor stick to the mud or gravel seabed , and then a length of (nylon) rope from the chain to the boat, or alternative heavy leaded rope.

This calculator also computes the anchor weight based on leisure boats (power boats or sail boats), and is not meant for large vessels.
