Fenders

MIL-HDBK-1025/5

In a double-boat slip system, provide two cleats about 3 ft

f)

(.91 m) apart secured to the edge of the headwalk and centered between the two

fingers.

Fenders

2.6.4.3

Fendering systems may include old rubber tires, discarded

a)

firehose, or hemp hawsers of makeshift quality for the bumper elements.

Special synthetic extrusion or molded shapes are preferred for small craft

dockage in floating systems.

The preferred type of bumper stripping for the edge of a

b)

finger or dock is a synthetic extrusion that runs along the top edge of the

outside stringer with a lip extending over the top. Neoprene and butyl rubber

provide adequate weathering resistant and resilient bumper materials.

Molded corner bumpers, also of synthetic extrusion, provide

c)

adequate protection for smaller craft. For larger craft, use corner wheels

especially where the finger extends all the way out to an interpier fairway

(primarily on floating system).

Plastic-tube vertical fenders, stretched between points of

d)

support or suspended from a top fastening with a heavy pendulum weight hanging

below the lowest possible point of hull contact, are also in use.

Fendering of fixed piers shall usually run vertically rather

e)

than horizontally. Most common fenders for fixed systems are vertical timbers

spaced at 8 to 10 ft (2.4 - 3.05 m) intervals along each side of a finger

pier. Size of timber shall range from 3 by 4 in. to 8 by 8 in. depending on

the size of the berthed craft.

Lengths shall be determined by the need to extend upward above

f)

the highest part of a gunwale at extreme high water and to extend below the

lowest rub strake at extreme low water.

Pier attachments shall be adequate to resist any moment that

g)

might be caused by cantilever bending loads up to the design moment of the

fender section.

Bolt heads or nut-and-bolt ends shall be countersunk into the

h)

fender pieces to avoid scoring of boat hulls.
