334-336 Differences
I have the 340, the next slip has a 336: Rating: I think you need to contact the factory for specific reasons why one is an A and the other a B. It may be as simple as the factory did not seek the A rating for the 336.After that, I can state that the 340 appears to be faster, has a different hull, different keel, different mast configuration, etc. All this may affect its righting moment, etc. But again, why not contact the factory and get an reliable response.Jim
