A. OCEAN: Designed for extended voyages where conditions may exceed wind force 8
(Beaufort scale) and significant wave heights of 4 m and above but excluding abnormal
conditions, and vessels largely self-sufficient.
(note: generally accepted as greater then 50 miles offshore)
B: OFFSHORE: Designed for offshore voyages where conditions up to, and including, wind
force 8 and significant wave heights up to, and including, 4 m may be experienced.
(note: generally accepted as 3 - 50 miles offshore)
C: INSHORE: Designed for voyages in coastal waters, large bays, estuaries, lakes and rivers
where conditions up to, and including, wind force 6 and significant wave heights up to,
and including, 2 m may be experienced.
(note: generally accepted as less then 3 miles offshore)
D: SHELTERED WATERS: Designed for voyages on sheltered coastal waters, small bays,
small lakes, rivers and canals when conditions up to, and including, wind force 4 and
significant wave heights up to, and including, 0,3 m may be experienced, with
occasional waves of 0,5 m maximum height, for example from passing vessels.
(note: sheltered coastal and inland waters)
Craft in each Category must be designed and constructed to withstand these parameters in
respect of stability, buoyancy, and other relevant essential requirements listed in Annex I, and
to have good handling characteristics.
NOTE: The Design category parameters are intended to define the physical conditions that
might arise in any category for design evaluation, and are not intended for limiting the use of
the recreational craft in any geographical areas of operation, after it has been put into service.
The physical conditions shall be determined from the maximum wind strength and wave
profiles, where wave profiles are consistent with waves generated by wind blowing at the
maximum stated strength for a prolonged period, subject to limits of the implied fetch and the
maximum stated wave heights, and excluding abnormal factors such as sudden change in
depth or tidal races.
For category D, allowance should be made for waves of passing vessels up to a maximum wave height of 0,5 m.
For category A, unlimited conditions apply as they reflect that a vessel engaged on a long
voyage might incur any conditions and should be designed accordingly, excluding abnormal
weather conditions e.g. hurricane

I know which one I would prefer to be in if the weather got bad and it isn't my 260DA. :smt021

Crazy for a 100 mile off shore trip......I don't think so.
Folks in our area do it all the time as we cross the Gulf from Panama City or Apalachicola to Clearwater....its about 185 miles and in the middle we are 90+ miles from either end. Additionally, most of the larger Sea Rays are not trucked but are water delivered to our area from Merritt Island or Palm Coast....same trip in a brand new boat with all the new boat bugs.
Be-careful out there, with friends like me, I'll bet you can't take your 20 footer to the Bahamas... I got a dollar....says you can't...
