Even if your boat is designed for them, the sea and wind conditions corresponding to
design categories A, B and C range from a category A storm to the most serious
conditions of the upper category C, including the risk of breaking waves or wind
squalls. These are dangerous conditions in which only a competent, capable and
trained crew with a well-maintained boat can work satisfactorily.
This handbook is not a detailed instruction for maintenance or troubleshooting. If
difficulties arise, please consult the boat builders or their agents. If a maintenance
handbook is provided, use this to maintain the boat.
Only use trained and competent staff for maintenance, repairs or alterations.
Alterations which can adversely affect the safety properties of the boat must be
assessed, carried out and documented by specialists. The boat builders cannot be
responsible for alterations to which they have not agreed.
