Flotation
Flotation Materials
There are specific performance specifications
for flotation materials based upon their location in a boat.
The level of performance required depends on the degree of
exposure to detrimental agents. Each section of the federal
regulation related to a specific type of flotation, i.e.,
Basic, Level, or Modified Level, provides requirements addressing
flotation material. The requirements refer the reader to Sec.
183.114 which follows.
The terms “bilge”, “engine
room bilge” and “engine room” have been
defined (see section 2.0). The first step will be to establish
the bilge and engine room bilge areas within the boat.
With the unloaded boat in calm, fresh water
and transversely level (static floating position):
- The bilge is the volume located below a line
parallel to the reference waterline. This line is located
4” up from the lowest point where water may accumulate
in the boat.
- The engine room bilge is the volume located
below a line parallel to the reference waterline. This line
is located 12” up from the point where water may accumulate
within this compartment (or connected compartments)
