Boat Classes
Sound Rowers recognizes a variety of boat classifications. The categories below identifiy the most common participants in our races, but participants are not limited to this list - all human powered craft are welcome.  Do note however, that some races may have constraints on either the size of the boat (for races with tight or congested turns), the suitability of craft to conditions (most races are NOT appropriate for flatwater or Olympic style sprint boats), or speed of craft (longer races may require an early start for slower craft, or not allow). Please check the individual race pages and with the individual race directors if you have any questions.
 
Awards are distributed to top finishes in class by gender. There are no special distinctions by age or weight.  
 
Sound Rowers Rowing Classifications

Rowing classes are based on boat length. OW-I (19' and under), OW-II (19-21'); OW-III (over 21')

Sound Rowers Kayak Classifications

Kayak classes are based on waterline length to width ratio.

 

Single kayaks: those boats with a L:W ratio less than 9.25:1 are in the Sea Kayak class (SK); between 9.25:1 to 10.99:1 are in the Fast Sea Kayak class (FSK); greater than 10.99:1 are in the High Performance Kayak class (HPK).

 

Double kayaks: those boats with a L:W ratio less than 10:1 are in the double Sea Kayak class (SK2); between 10:1 and 13:1 are in the double Fast Sea Kayak class (FSK2); greater than 13:1 are in the double High Performance class (HPK2).


Sprint/Olympic flat water boats are based on number of paddlers:  K1, K2, K4. Participation may be constrained by conditions.  Positive floatation required.

 

Below is a parial list of sea kayaks by manufacturer with their L:W ratio and respective class.  Note that not *all* boats are listed, as new boats are developed and brought to market at an ever increasing pace.  These are boats that have either been personally measured, or had complete waterline specifications published by the manufacturer or Sea Kayak magazine.  Check our article on classficiation methods to see how this is done.
