The Dennis Harbormaster Department listens to many different channels. The best way is to hail for us on channel 66. Please speak clearly and slowly. If for some chance we don't answer, try again. During the season, the radios are very busy, you may have been stepped on by another. If it is an emergency, and you can't reach us on channel 66, try channel 16. If you still can't reach us either call for the Coast Guard or call via cell phone the Dennis Police at 911. If you are on Bass River, call us by "Dennis Patrol".
Remember to remain calm and always protect yourself, your passengers, and your boat.
