April 26 – May 4.
The islands of the Abacos define the borders of three expanses of water, The Sea of Abaco, The Little Bahama Bank, and the Bight of Abaco.
Blue Wing has spent quite a bit of time in the Sea of Abaco where most of the settlements, tourist attractions, restaurants, bars, marinas, hardware stores, grocery stores, and other comforts of society are located. She sailed through the sparsely populated Little Bahama Bank in the northwest Abacos, stopping only briefly for overnights rests, on our return to the states last season and at the beginning of our Bahamas journey this past December. But Blue Wing’s bow has never parted the waters off of the western shore of Great Abaco Island, the elusive and secluded Bight of Abaco.
There are only a few ways into the Bight of Abaco. The only northern route goes from the Little Bahama Bank through the narrow, winding, and very shallow Spence Rock Channel. There are a couple of channels into the Bight from the south, but in order to reach them, one must first transit the very deep, open waters of the Northwest Providence Channel from either the closest anchorage, 30 miles away in the Berry Islands or the closest marina, 50 miles away at Grand Bahama. There are few settlements in the Bight that are accessible to sailing vessels. This deficit of civilization combined with the limited, tricky, and uninviting entrances make it an area that is rarely cruised. So, of course, I wanted to go!
On Friday morning April 26, we parted ways with Jules, Jeff, and Neil. We had plans to be in Green Turtle on May 3 for a two-day festival, but until then we had no definite agenda. As our new friends headed back south to their next destination, we headed in the opposite direction across the Little Bahama Bank towards the Bight of Abaco to do a little reconnoitering.
Since we were way too far away (a two or three-day sail) from either of the southern channels into the bight, we chose to take the northern route, but this meant first figuring out if Blue Wing would be able to pass through, without going aground, the narrow stream of water leading into this remote area.
We took our time getting to Spence Rock Channel, stopping at and exploring Allans Pensacola Cay, and spending a night outside Foxtown, before finally arriving at Little Cave Cay at the top of Spence Rock Channel.
We needed to determine two things: When exactly high tide was and where the deepest parts of the channel were. Our chart told us that high tide was 2 to 4 hours after high tide in Nassau. We have a tide chart for Nassau, but we wanted to be more exact than 2 to 4 hours. Parts of the channel are as shallow as 4 feet at low tide, so we were going to need to know exactly when the tide was at its highest in order to gain the extra 3 feet of water we would require to get through. Although both our paper charts and our GPS showed water depths in the channel, we wanted to make sure the readings were accurate and that nothing had changed before taking Blue Wing through the tricky passage and possibly finding ourselves stuck on the bottom with no help to be found for very many miles.
Our first day at the channel was spent determining the time of high tide. We spent the afternoon on the boat checking our depth meter every 15 minutes recording the numbers as they went up, peaked, and went back down.
The next day we endeavored to complete the second part of our recon mission and traverse the channel in Fever, measuring water heights. Since we don’t have a handheld depth meter Greg tied a rope to our dinghy anchor and marked it off at inch intervals, which we planned to throw in the water at different locations and record the depth and time on our tablet. Of course, Fever was still motorless, so we were planning to row the 4-mile long channel. As soon as we moved Blue Wing closer to the mouth of the channel (out of the lee of the island) our plan started to look even more difficult than it sounded. The wind was up and there was no way we were going to be able to row and do everything else we wanted to do with any kind of ease.
We pondered the situation for a little bit before I suggested that we just do it in Blue Wing. The top part of the channel is not quite as shallow as the bottom part and the middle part of the channel has over six feet of water (ample enough for us). We could follow waypoints through the top part of the channel, recording times and depths as we went, then turn around in the middle and do the same thing on the way back out.
It was about mid-tide when I took the helm, we enabled tracking on the GPS so we could record our route, then motored slowly down the narrow passage. We had every waypoint numbered, so as I hit each one, I called out and Greg recorded water height and time. The chart was looking pretty accurate until we saw the depth meter sink to 6 inches. It was an extra tense moment in an already tense passage but didn’t last long as we skimmed through it and got back on track. Greg made note of the spot on the tablet. Finally, we reached the middle of the channel and turned around to retrace our steps. No scary shallow spots on the way back!
With our recon mission as completed as it was going to get, we decided to work our way back to Green Turtle for the festival. We spent another night anchored outside of Foxtown, before heading back to Allens Pensacola Cay where we explored the neighboring Guineamans Cay. On May 2 we decided to head back to Green Turtle. It was drizzling as we left Allens Pensacola, but as we continued towards our destination the weather worsened and we found ourselves fighting wind and rain. We abandoned our Green Turtle plan and tucked up into the Crab Cay anchorage. That night the winds howled up to 39 miles per hour with rain ceaselessly pounding Blue Wing’s deck. A group of seven boats from the Emilia Island sailing club fresh in from a transit from Florida fell in behind us at the anchorage that evening and a couple of them dragged anchor that night. The next day was brighter to the south but still dark in the north. The sailing club left, but we stayed through another day of rain and angry skies, missing the start of the Green Turtle festival.
Finally, on Saturday the rain abated and we decided to head out. The weather had worn us down and we were starting to feel adventured out. We decided to abandon our Bight of Abaco Plan and head back to Florida, but first, we needed to head back to Green Turtle to fuel up and water up and if we were lucky, catch the end of the festival.

Looking to make that passage through Spence Channel from North to South this winter in a Gulfstar Hursch 45 with 6 ft draft. any help would be appreciated. Been all through the Exumas so shallows don’t scare me. Thanks.
Hey Ron – We never did the Spence Rock Channel – although we did do a little recon work towards doing it. I originally got the idea to do it from this blog post I found online – http://www.ciekurzis.org/Bight%20of%20Abaco/Bight%20of%20Abaco.htm These guys were in a 7 foot draft boat, but did it with a full moon high tide at night. I remember during our recon of the Channel, that there were some really scary shallow spots where our depth finder showed us hitting bottom (we draw 6 feet, also), but we didn’t hit and we decided it must have been some tall grass throwing our depth finder off. We only went about half way down the channel and turned around. Generally, if I remember correctly, we always had at least a foot under the keel.
