. DL + ULL: 10” minimum to top of
deck.
c. DL + LPL: 13” minimum to top of
deck.
(1) A reduction of freeboard will
occur, but will probably be limited
to the general area around the
point of live load.
(2) Reduced freeboard is to be further
limited by a maximum localized
deck slope of ¼” per foot in any
direction resulting from the live
point load.
d. DL + ULL + LPL: 8” minimum to top
of deck.
5. Boarding floats are to be designed to
withstand wind, wave, current and impact
loadings, applied to both floats and tied up
boats, that may reasonably occur during
the life of the structure as the result of its
location and exposure.
a. Minimum boarding float wind
loading is to be 25# per linear foot of
float. This is predicated on a uniform
wind load of 15#/ft 2 applied to a
maximum allowable freeboard
exposure of 20”.
b. Minimum boat wind loading is to be
45# per linear foot of float. This is
predicated on a uniform wind load of
15#/ft 2 applied to an estimated in-thewater
average profile height of
trailerable boats of 3’.
c. The float and boat wind loading is to
be applied concurrently, resulting in a
combined loading of 70# per
20
