Navigating Cuts in island keys or the Cays of the Bahamas

Cruising many of the islands in the southern latitudes, especially in the Bahamas, will require careful attention, knowledge and skills when navigating in and out of the cuts between the inside and the ocean side of the islands. The Bahamas are known for narrow and shallow cuts. These difficult cuts can be further complicated by other conditions caused by the tides, currents and weather.

Considerations before navigating a cut.

• How narrow is the cut, sometimes this is measured in the number of units of the length of your boats beam.

• Are there shoals or reefs awash or underwater, which are not visible.

• What is the depth of the water at the cut.

• Weather – Direction of the wind, Blowing into or out of the cut

• Wave, swell height

• Tide coming in or going out, Ebbing or Flooding, is it against the wind?

• Surges and Currents

• Based on all the potential hazards above, it is most advisable to enter cuts only during day light hours.

• Time of sunset and the time of the moon rise that evening

• Ask for advice from local knowledge

 

Narrow cuts can be difficult to navigate, ensure your approach is correct and safely clear of any invisible shoals or reefs. Always refer to paper charts, for the Bahamas Explorer Charts are the best! http://www.explorercharts.com Your chart plotter can not be trusted 100%, it can only be used as a general guide, especially in the Bahamas. Consider the depth of the water, consider the tide which can alter that depth by as much as 4 or 5 feet in the Bahamas. Consult your tide tables. If there are large swells or waves, in the trough of the wave can vary by 10 feet from top to bottom. The boat can drop by 10 feet in very large swells or waves. So if you are in a charted cut of 20 feet depth and your boat draws 6 feet, you may feel you are ok. But in a 10 foot trough combined with a low tide, the depth can be 14 feet lower in the trough and your keel will hit bottom. This could be catastrophic.

Now add to this, tidal current and surges, as an enormous amount of water is either entering or exiting the inside of the islands. These surges and strong currents can reach 4-7 knots. These currents and surges can push your boat from one side of the cut to the other, spin the boat around, and disorient you at night. You may be washed onto the reef or shore, you may even steer towards either in your disorientation. This is why I don’t advice entering one after dark, especially if there is no moon. The moon rise can be very late in the evening, know when the moon is rising if you are caught on the outside.

Here are a couple of interesting experiences we have had entering or exiting a cut.

Recently exiting Dotham Cut near Bitter Guana Cay, Exumas – the navigable area is pretty wide and the depth is good. We were making about 5 knots and exiting with an ebbing tide and the wind was behind us. These were perfect conditions for exiting the cut. Even so the boat’s keel was pushed from side to side and concentration was necessary. Our speed over the ground increased from 5 knots to 11 knots with the current. This show me that the out going current was about 6 knots. There were a few other boats trying to enter this cut in these conditions – can you believe that! They exiting to the ocean side somewhere up the cays and maybe did not consider how and when they will come back in. They were having to beat up wind into the cut, with an opposing current of 6 knots. They would have to sail faster than this to make any way at all. A few boats attempted – then had to bail, and some were spun around by the keel as they aborted. Now you don’t want to be trying this at night! I was amazed that a boat actually made it in. The tactic she used was to hug the shore very closely, where the current would be far less, still having to beat upwind, with engines blazing. They were making very slow way, but eventually made it in, I am sure they were white knuckling the whole way.

When you promise friends “A time and a place” this can often lead to trouble. We had to be there by a certain time. Never promise a time and place, just let them know you can only promise one of the two. If there is a place they want to meet you, then you’ll let them know when you have safely arrived at the place, and they can fly down. If it is a time they wish to meet, then you will let them know what place you are at during that time, and they can fly there. But to guarantee both is very difficult and can be dangerous if your trying to get there in the wrong conditions.

North Bar Channel in the Abacos, – on another occasion, my wife and I were anchored in this southern end of the Abacos on our way to meet friends in Nassau. The cut looked wide, but the navigable area was about half the size, both sides had dangerous reefs under the surface and could not bee seen. The weather was heavy on the outside and large swells were coming in the cut – as high as 20 feet! It was unbelievable. There were boats trying to come in on this surf, the depth under normal conditions was 25 feet, but in this case the boats would have hit bottom. I radioed a couple of boats about to make attempts to enter, I convinced them to abort. We decided to stay the night at anchor and see if the next day would be better.

North Bar Cut!

North Bar Cut! You can see crashing waves of 20 feet in height.

Thankfully the next day was better, but still rough conditions, the swells were down to about 10 feet, and we decided it could be accomplished succesfully. There were range markers on the main land on the inside of the cut, these are situated so boats entering could line up the range markers and make a safe entry and avoiding the reefs. But for us exiting, we would have to be looking behind us in order to line up the markers. So this was our plan. Roxane would straddle the cock pit table, facing to the aft of the boat, holding on for dear life. While I helmed and faced forward as she would tell me to steer a little to port or starboard. As we exited the boat rode over 10 foot waves, and slammed down as it crested. The kids down below were enjoying the tummy hills, while playing nintendo. Yes we have some crazy kids, they grew up on boats and this was par for the course.

Ship Wrecks There are many ship wrecks recorded by folks trying to enter these type of cuts under various unsafe conditions. Some folks aborting such rallies as the 1,500 to the BVIs. In bad weather, it is much safer to stay offshore, than try to navigate an unknown cut, in a country you did not plan to land on, and maybe you don’t have the paper charts, you are having to rely on your chart plotter, (Chart plotters not accurate) and most likely entering at night.

Conclusion The best time to approach a cut, would be on slack tide, during day light with calm weather conditions. Realizing that this is not always possible, ensure that more of these conditions are with you, rather than against you. Enter on a flood tide, and exit on an ebb tide. But also consider wave and wind condition against the tide, since this will pick up the seas to much larger waves. Ask for local knowledge when ever possible.

s/v Black Diamond

I have been boating for over 25 years, at the age of 43, this is more than half of my life time. Starting out with a number of smaller power boats, then switching to sail about 8 years ago. I have sailed various boats from wind surfers, dinghies (lasers), keel boats from 26 to 45 foot yachts. I live in the area of Toronto Canada and sail mostly on Lake Ontario. I have been racing yachts for the past 7 years. I have also entered many long distance races such as the Fort Lauderdale to Charleston, completed in 2 days 8 hours, we received 4th place in division, 8 minutes in PHRF behind a 3rd place trophy. Then 4 times finishing the Susan Hood, a 75 mile over night race, 4 times entered in the Lake Ontario 300 the worlds longest fresh water race, a 308 knotical mile race around the perimeter of Lake Ontario. My crew and I on Black Diamond finished in 2 days 12 hours in 2009. In 2009, delivering the boat back up to Canada from the Bahamas we entered in a couple of interesting races, one from Fort Lauderdale to Charleston described as a sled ride up the gulf stream, the Charleston race week regatta series and the New Year's Day Staniel Cay Regatta in the Exumas, Bahamas. This race we came in 2nd over entire fleet, only lost by 3 minutes in a 2 hour race to a 47 footer. This was a boat for boat race, no PHRF scoring. "Twenty years from now you will be more disappointed by the things that you didn't do, than by the ones you did do. So cast off the bowline, Sail away from the safe harbour. Catch the trade winds in your sails. Explore. Dream. Discover." Mark Twain Blue water experience include yacht deliveries from the Abacos, Bahamas to Charleston South Carolina 2006. This delivery was a non-stop, 3 and half days, total of 500 miles. We crossed parts of the Bermuda Triangle, and during most of the delivery were over 200 miles offshore. The delivery of Black Diamond a 40 foot Jeanneau racer/cruiser has been delivered to New York City and then offshore to Florida and the Bahamas from Toronto, Canada. This delivery from NYC to Florida was completed 100 miles offshore, for a distance of over a 1000 miles non-stop to Jacksonville, Florida. Completed in what might be a cruisers record of 5 days 3 hours non-stop offshore. This fall my family and I added another 500 miles of sailing throughout much of the Bahamas. Spending 6 weeks aboard Black Diamond sailing the Abacos, Nassau and the Exumas. I then sailed the boat back to New York, completely offshore, entered a few races along the way, and back to Toronto through the Hudson River and Erie Canal. During the 2009 season, we sailed Black Diamond off the dock 148 different days out of 365, winning the Vacant Dock award the second year in a row. Most recently, 2011, completed the delivery of friends boat Tracey & Nilson Ruiz, from Tortoal, BVI to New York. Tortola to Georgetown Bahamas in 5 days non-stop. Last leg from Charleston to New York over the momorial day long week-end non-stop Friday to Monday in 4 days. All completed safe and sound without incedent. Need any deliveries let me know. I am also an Open Water Certified diver and an active member of the Canadian Power and Sail Squadron, certifications included Power/Sail boat handling, Seamanship Sail, Piloting/charting, GPS Navigation, Extended Offshore Cruising and a VHF Radio operation license. I hope to further my education, qualifications and experience in long distance cruising and racing. One of my goals is to obtain a commercial Captains License.
