Are fairlead chocks and/or bullnose substantial enough to handle strain of towing?
Is the deck area surrounding bitts or cleats in good condition?
(Note. If not, consider non-destructive testing)
Is the tow bridle fairlead angle sufficiently straight to preclude excessive side loading to fairlead
If mooring bitts are used, state the condition of bitts and surrounding deck area. If any doubt eix ts,
request that the area be non-destructively tested.
All towing bridles, when rigged correctly, must have a backup securing system. This Is normally accomplished
by using wire rope of appropriate size (able to lace through chain links) and taking sufficient bights of wire from
a second securing point (bitts, heavy cleats, etc.) and lacing the wire rope through the after end of links in the
chain bridle (no less than four bights). Size and number of bights or wire should equal the strength of the chain
used in the bridle. If a towing pad is used to connect the bridle to the tow, the backup wires must be laced
forward of the towing pads. If a set of mooring bitts is used as a securing point for the bridle on the tow, the
wire should be laced through the chain links that remain astern of the bitts after the three or more "figure eights
" are secured on the bitts. There must be at least 3x diameter plus one wire clip on each bitter end of the
backup wire, aligned in the same direction with "U " on bitter end side placed 6 rope diameters apart. Is the
towing bridle rigged as stated above?

Distance from towing pad or bitts to backup point
If mooring bitts are used, with sufficient strength to withstand the entire towing load, does the towing bridle
have a round turn followed by three or more complete "figure eights" around bitts before the end of the chain is
laced with the backup wire?
When using a chain bridle and sets of bitts as the towing point, it is preferable to terminate the chain before
reaching the bitts, using wire to make the connection to the bitts. When load-sharing between two sets of bitts,
take only one round turn around
