Type I:
Also known as an off-shore jacket, it provides the
most buoyancy. It is a PFD for all waters and is
especially useful in rough waters where rescue
may encompass additional time. It is designed to
turn most unconscious users in the water to a true
face-up position. Type I PFD is available in adult
& child sizes Buoyancy minimum poundages are
15.5 adult, 11 medium child, and 7 for small child
and infants.
Type II:
Also known as near-shore buoyant vest, it is
recommended for calm, inland water where rescue
time will be minimal. It will turn some unconscious
people face-up in the water but not as numerous
as Type I. They are available in adult, medium child,
along with infant and small child sizes.
Type III:
Known as a flotation aid it is good for calm, inland
water or where there is a chance for quick rescue.
It is designed so wearers can place themselves in
a face-up position in the water. The wearer may
have to tilt their head back to avoid face-down po-
sitions. Type III offer the same buoyancy minimum
poundages as the Type II. They are generally the
most comfortable for continuous wear. Float coats,
fishing vests, and vests featuring designs for vari-
ous sport activities are examples of Type III.
Type IV:
Intended for calm, inland water with heavy vessel
traffic, where help is constantly present. It is de-
signed to be thrown into the water for someone
to grab on to and held until rescued. It is not de-
signed to be worn. Type IV includes ring buoys,
buoyant cushions, and horseshoe buoys.
Type V:
Also known as a special use device this is the least
bulky of all PFD's. It contains a small amount of in-
herent buoyancy, and an inflatable chamber. It is
rated even to a Type I, II, or III PFD (as noted on the
jacket label) when inflated. Some Type V devices
provide significant hypothermia protection. Variet-
ies include deck suits, work vests, board sailing
vests and Hybrid PFD's. Remember that this Type
V type PFD may be carried instead of another PFD
only if used according to the approval condition on
the label.
Note: A water skier or wake boarder is considered
on board the vessel and a PFD is required for the
purposes of compliance with the PFD carriage re-
quirements. It is advisable and recommended for a
skier or wake boarder to wear a PFD designed to
withstand the impact of hitting the water at a high
speed. "Impact Class" marking on the label refers to
PDF strength, not personal protection. Some state
laws require a skier or wake boarder to wear a PFD.
