Navigating the unknown
When it comes to cruising in unfamiliar waters, even veteran boaters get sweaty palms and make beginner mistakes while navigating in unfamiliar waters. Instead of regaling you with mine, I’m passing along 10 tips I learned the hard way.
1. Pre-plot your course
This is really a double tip, because you have to buy the right charts before you can pre-plot your course. Get an up-to-date chart that shows an overview of the entire area as well as detailed charts of the harbors along the way.
Spread the charts out at home, and plot your route ahead of time. Pencil in the courses you’ll be steering along with their compass headings.
2. Highlight problem areas
As you plot your course, you’ll find shallow water, rocks, reefs, and other areas of concern. As you plot your course safely around those areas, use sticky notes to remind you to be extra cautious in those areas.
3. Buy a cruising guide
Cruising guides provide insider information on everything from currents to the best place to stop for hamburgers. Think of them as a supplement, not a replacement, to regular charts.
4. Call ahead
Pick up the phone and call the harbormaster at your destination. Ask what you should know ahead of time. You may discover you have to reserve a slip or mooring ahead of time or that the navigation lights are turned off.
5. Be prepared
Study your chart and cruising guide to help you prepare for conditions at your destination. If the harbor bottom is grass and weed, carry a suitable anchor. If it has a large tidal range, carry long-enough dock lines and extra fenders.
6. Follow the locals
If you aren’t sure about the channel into an unfamiliar harbor, look for a local fishing boat. Try to raise the crew on your VHF, explain your situation and ask if you can follow them through the channel. Let them know your boat’s draft, so they don’t cross an area that’s too shallow for your boat.
In harbors with shoals and breaking surf near the entrance, there’s no shame in calling the harbor patrol or Coast Guard for advice. They may send a boat to lead you in if the conditions are dangerous.
7. Arrive before dark
You’ll have enough problems sorting out unfamiliar waters without complicating the situation with darkness. When planning your departure time, figure out the time it takes to reach each destination and plan to arrive several hours before sunset.
8. Know the buoy system
If you’re entering another country or crossing from ocean to inland waters, be aware that the buoyage may be different.
9. Program your electronics
Enter waypoints you’ve marked on your chart into your GPS receiver. By programming these waypoints in advance, you’ll have a useful tool for finding your present position, seeing how far you have to go, determining the course you need to steer, and getting a sense of how fast you’re covering the distance.
If your built-in GPS charts don’t cover the area you’ll be entering, buy a navigation chip or download additional chart information from a new or updated CD-ROM.
10. Ask friends
You can often get useful advice and tips from friends who are familiar with your planned destination.
When it comes to unfamiliar waters, always err on the side of caution. If you aren’t sure of something—location, water depth, course—stop your boat until you know how to proceed.
Taking a few simple precautions will allow you to enjoy the sense of adventure you get from visiting new places, and you’ll have an easier time finding your way the next time.–Al Ponzio
