HIGH-SPEED FERRY ROUTE:
Especially in calm weather and when sailing or anchoring in shallow waters, 
the waves from high-speed ferries can cause an increased risk of damage or grounding. 
Smaller vessels should exercise spesial caution when sailing or anchoring near the 
routes of the high speed ferries. The inconvenience from the waves of the ferries will 
decrese on greater water depths. The precautionary measures with regard to these 
waves should be the same as is sailing in areas with other shipping.
