Summary
NAHA, OKINAWA
SUMMARY
The conclusion reached in this study is that Naha Harbor is a poor haven during typhoon conditions. The key factors in reaching this conclusion were:
1. Lack of sheltered berths.
2. The threat of other vessels adrift in the confined harbor.
3. High sea states within the harbor area for winds of 25 kt and greater.
4. Poor anchor holding action of the harbor bottom.
It is recommended that all U.S. Navy and Military Sealift Command ships take action to evade at sea when typhoon conditions threaten Naha, Okinawa. Naha Military Port policy is to evacuate vessels from the port prior to the arrival of a typhoon.
