Anchoring is done for two principal reasons: first, to
stop for fishing, swimming, lunch, or an overnight stay and secondly, to
keep you from running aground in bad weather or as a result of engine
failure. Anchoring can be a simple task if you follow these guidelines:
- Make sure you have the proper type of anchor (danforth/plow/mushroom).
- A three to six foot length of galvanized chain
should be attached to the anchor. The chain will stand up to the
abrasion of sand, rock or mud on the bottom much better than a fibre
- A suitable length of nylon anchor line should be
attached to the end of the chain (this combination is called the
"Rode"). The nylon will stretch under heavy strain cushioning the
impact of the waves or wind on the boat and the anchor.
- Select an area that offers maximum shelter from
wind, current and boat traffic.
- Determine depth of water and type of bottom
(preferably sand or mud).
- Calculate the amount of anchor line you will need.
General rule: 5 to 7 times as much anchor line as the depth of water
plus the distance from the water to where the anchor will attach to
the bow. For example, if the water depth is 8 feet and it is 2 feet
from the top of water to your bow cleat, you would multiply 10 feet by
5 to 7 to get the amount of anchor line to put out (See diagram
- Secure the anchor line to the bow cleat at the
point you want it to stop.
- Bring the bow of the vessel into the wind or
- When you get to the spot you want to anchor, place
the engine in neutral.
- When the boat comes to a stop, slowly lower the
anchor. Do not throw the anchor over, as it will tend to entangle the
- When all anchor line has been let out, back down on
the anchor with engine in idle reverse to help set the anchor.
- When anchor is firmly set, use reference points
(landmarks) in relation to the boat to make sure you are not drifting.
Check these points frequently.
Anchoring a small boat by the stern has caused many to capsize and sink.
The transom is usually squared off and has less freeboard than the bow.
In a current, the force of the water can pull the stern under. The boat
is also vulnerable to swamping by wave action. The weight of a motor,
fuel tank, or other gear in the stern increases the risk.
