Securing a Vessel

When securing a vessel to a dock or float, examine the cleans, railings, etc. to determine if they are strong enough to hold the vessel.

Following is the recommended manning in which vessels should be tied up to a dock or float.

Vessels 20-40 feet in length

1. A proper lead bow line and stern line should be used. If mooring in a river or where a strong tie may be expected, a spring line should be run in the direction opposite of the current.

2. Be sure the lead of all lines are long enough to allow for the rise and fall of the tide.

3. If, due to the rising tide, there is any danger of the line pulling of the top of the cleat or piling, it is recommended that the eyes of the line be passed under the “bull rail” and then over the cleat or piling.

4. Be sure there are enough turns or wraps taken on the cleans aboard the boat to avoid half hitches if possible as they may jam in the event of great strain.

5. Lines should be at least 1/2 to 3/4 inch polypropylene for vessels up to 40 feet in length.

Vessels over 40 feet in length

1. A proper lead bow and stern line should be used. In addition two spring lines, one leading forward and the other leading aft should be used.

2. The same precautions in items 2,3 and for above should be observed.

3. If your vessel is the outside  in a group, in addition to running lines to the adjoining vessel it is advisable to run an extra bow and stern line to the dock.

4. Lines should be at least 1 to 1-1/4 inch polypropylene for vessels over 40 feet in length.
