Lots of presumptions, but presuming the mooring
is properly maintained and presuming the vessel is of appropriate size for the mooring
the vessel’s mooring bridle
lines should be made fast as short as practicable. The load goes to the mooring pennant and moorings.
In fact, in some locations, park or mooring authorities ask/require their pennant be taken aboard and made fast to the vessel without a bridle
. This allows moorings to be spaced closer together without having to account for different swing arcs.
Chapman’s recommends a pennant length of ~2.5 times H, where H Is the vertical distance from the water’s surface to the pulpit.
This is in contrast to anchoring
, in which the anchor
snubber bridle needs to be long enough to have adequate stretch and absorb more of the load, rather than the windlass
