There are four design categories of boats based
upon their ability to withstand wind and sea or water
conditions:
A. Ocean
Wind speed: above 40 knots (46 m.p.h.)
Wave height: above 4 meters (13 feet)
Boat may be used for extended ocean
voyages.
B. Offshore
Maximum wind speed: 40 knots (46 m.p.h.)
Maximum wave height: 4 meters (13 feet)
Boat can be used offshore, but not for
extended ocean voyages.
C. Inshore
Maximum wind speed: 27 knots (31 m.p.h.)
Maximum wave height: 2 meters (6.5 feet)
Boat use is limited to coastal waters, large
bays, estuaries, lakes and rivers.
D. Sheltered Waters
Maximum wind speed: 15 knots (18 m.p.h.)
Maximum wave height: 0.5 meters (1.5 feet)
Boat use is limited to small lakes, rivers and
canals.
Your 58 DB
(585 DB) is Design Category B.
The wind speed and wave height specified as the
upper limit for your category of boat does not mean
that you or your passengers can survive if your
boat is exposed to these conditions. It is only the
most experienced operators and crew that may be
able to operate a boat safely under these conditions.
You must always be aware of weather conditions
and head for port or protected waters in sufficient
time to avoid being caught in high winds and rough
water. Do not take chances!
When visibility becomes impaired because of
weather, time of day or high bow angle you must
slow down so that you have sufficient time to react
if an emergency occurs. Nearby boats face similar
risks in avoiding a collision with you.

ONSIDERATIONS
•
Know how your boat handles under different
conditions. Recognize your limitations and the
boat’s limitations. Modify speed in keeping with
weather, sea and traffic conditions.
•
Instruct passengers on location and use of
safety equipment and procedures.
•
Instruct passengers on the fundamentals of
operating your boat in case you are unable to
do so.
•
You are responsible for passenger’s actions. If
they place themselves or the boat in danger,
immediately correct them.
Death or serious injury can result if you fail to observe
these safety rules:
•
Anyone who controls the boat must have
taken a boating safety course and have
trained in the proper operation of the
boat.
•
Always operate the boat at speeds that
will not put people or property in danger.
•
Be constantly aware of conditions in all
directions when underway and before
turning.
•
Reduce speed, use a lookout to identify
possible hazards or difficulties, and turn
on navigation lights when:
- visibility is impaired;
- in rough water; and
- in congested waterways.
•
Watch your wake. It can capsize a small
boat or damage moored boats or other
property. You are responsible for damage
caused by your wake.
