Mona Passage

For those of you who've been following our logs, here's a question to see if you've been paying attention: If Caribbean Soul is traveling southeast from the Dominican Republic (DR) to Puerto Rico, from which direction will the wind blow? If you answered "southeast" or "on the nose," then you qualify for a windward trip down the Thorny Path.

Bruce Van Sant in his cruising guide states: "Sailing or motoring to windward on this coast during so-called moderate trades (20-25 knots, 6-8 foot seas) rates as flat out suicidal." So what is the southbound sailor to do? The answer is to play the nightly island lee. During the night, an island gives off the heat it absorbed during the day. This process creates a night lee, an area near the coast where the wind and seas are calmer than they are offshore. In fact, Columbus used the night lee to move his ships around the coast of the DR. Whereas Columbus had to use rowboats to move his ships, the modern sailor uses the auxiliary engine to motor around the coast during the nightly taming of the trade winds. Frontal systems can also bring a temporary disruption of the trade winds and provide a longer weather window for putting miles under the keel. Such a front is in our forecast, providing a rare opportunity to go straight to Puerto Rico.

March 16

A group of six boats prepare to depart Luperon on Friday evening. Our weather router Chris Parker has given the thumbs up. An approaching cold front will bring lighter winds and calmer seas before reaching the DR and stalling on Sunday. We'll need to arrive in Puerto Rico by Sunday evening before the tradewinds rebuild on Monday. The biggest concern is the possibility of squalls that will form Saturday afternoon as the cold front approaches the northern coast of the DR.

At 7:00 P.M., we depart the harbor with MoonSail, Sol y Mar, Perseverance, and two other boats. Although the wind is dying, we know the night lee has not yet set in and that whitecaps are still rolling offshore. However, we want to leave with enough daylight to dodge the fish buoys in the channel. Shian and Gypsy Dancer, friends from the UK, decide to wait for the night lee and use spotlights to dodge the buoys after dark.

Within a few minutes of leaving the harbor's shelter, we're facing much worse conditions than we bargained for. The wind is howling over 25 knots and the boat rises and falls in an 8-foot northeastly swell. Several boats discuss turning around, although no one does because the return trip down wind would probably be worse. If Van Sant, a Luperon resident, is listening on his VHF radio, he's undoubtedly laughing at us.

The first 6 miles out of Luperon are considered difficult even in optimum conditions. The boat rides comfortably enough as it plows into head seas and wind, but our speed doesn't exceed 4 knots for several hours. The night lee finally appears around 11:00 P.M. and conditions vastly improve. For the remainder of the night, we motor just a few miles off the coast in light winds and a moderate swell.

March 17

We round Cabo Frances Veijo just after sunrise before the wind picks up. We even manage to carry both the main and headsail for awhile. As forecast, by afternoon the wind is too light and on the nose for the headsail, but the main sail stays up for the rest of the trip to stabilize the boat.

It's late in the afternoon when the tense voice of Dori on Sol y Mar comes over the VHF radio. Their engine has stopped running and they will have to sail into Samana instead of continuing on to Puerto Rico. MoonSail offers to alter course and meet them in a small anchorage outside Samana. Along with Perseverance, we decide to follow suit. However, after some discussion, it's decided that it will be easier for Sol y Mar to drop anchor under sail at night if there are fewer boats around. We continue to Puerto Rico with Perseverance.

By sunset we're rounding Cabo Cabron and Cabo Samana. Here we see the cape effect, where wind and waves intensify as they're compressed along the cape. A few hours later, we look astern to see thunderstorms building off these capes. We hope our friends on Shian and Gypsy Dancer are ahead of the storms. During the night, we use our radar to dodge several rain squalls.

By sunrise on Sunday, we're entering the infamous Mona Passage. This 61-mile body of water lies between the eastern coast of Hispaniola and the western coast of Puerto Rico. Strong headwinds, rough seas, and thunderstorms are common obstacles to a safe passage. For the southbound sailor, the Mona Passage is much anticipated and dreaded.

The first challenge is the Hourglass Shoal just off the Dominican coast. Here the waters of the Equatorial Current cascade out of the deep Puerto Rican trench and stack up on the shallow bank. Thanks to careful weather planning and good luck, the winds are light today and the swell is long and gentle. We navigate well north of the shoal and notice slightly rougher seas for a few hours. By midday, we're in the shipping lanes in the middle of the Mona. Four ships pass within three miles of us, and many others appear on our radar. I'm glad we're passing these ships in daylight rather than in darkness when they would seem closer and more intimidating.

Since leaving George Town, Nick has been optimistically trolling fishing lines behind the boat without a single bite. Today his luck changes and he snags a large wahoo on the hand line. It's a gorgeous fish and will feed a crowd--something to look forward to.

By late afternoon, Perseverance has determined that they will run out of fuel before arriving in Mayaguez. We arrange a rendezvous just off Isla Desecheo. Richard dinghies over and picks up two jugs of fuel. Soon we are both back on course passing Isla Desecheo on the north side. The Mona Passage is known for violent thunderstorms that form off the west coast of Puerto Rico in the afternoons and drift out the sea to pound the hapless sailor. As we pass the towering island about a mile off our starboard side, a non-convective squall drifts offshore and cloaks the island making it invisible. We pass within a few hundred feet of the squall's edge, but it doesn't cause us any trouble.

By 5:00 P.M. we're entering the commercial harbor at Mayaguez with Perseverance. We're thrilled to have had such an uneventful trip across the Mona Passage and finally be in Puerto Rico. Around sunset, we see Shian approaching on the horizon. Gypsy Dancer arrives soon after dark. We're all exhausted but elated. A major hurdle has been crossed and we'll all sleep well tonight in boats that sway quietly on anchor.
