No Name Harbor, Key Biscayne to Boot Key Harbor, Marathon, FL, AICW mm 1096



May 22-23

The trip from No Name Harbor to Marathon is about 115 miles, so it would take us about 13 hrs if we could cruise at 9 mph.  First light would be around 6:15 am and last light around 8:30 pm, making for about 14 hrs of daylight at this time of year and not leaving much leeway.  We set an alarm so that we would have enough time to check the weather and sea conditions one last time, take Sasha to shore, and still weigh anchor by first light.  Our weather window was forecasted to be closing up by the end of the day, so we had to decide whether to go ahead and leave as planned or whether to stay another 5 days or so for the next window.  Since Florida Bay was still forecasted to be calm, we decided that we could duck inside at several points if conditions got too rough for us.

We thought we were doing well to leave by 6:15 am, but the sailboat in the anchorage left about 20 minutes before us.  We had read that the inlet at No Name Harbor could be a bit bumpy, so we were glad to be going through it in good light.  Wave heights were about 3 ft at 4 second intervals, so it was, indeed, a bit rolly after we turned to head more south since the waves were on our beam.  Conditions smoothed out around 8 am as forecasted, so we started to settle in for a nice, uneventful cruise.

Just about that time, I noticed something in the water directly ahead, bobbing up and down.  At first I thought that someone had lost a life jacket or fender, but since it looked like 2 separate components at times, I thought “Oh great, the only crab pot in this area and we’ve programmed our course to go right over it!”  I changed course to dodge around it, swinging wider as we got close enough to recognize exactly what it was.  Apparently, during sea turtle nesting season, the turtles mate right offshore and then the females go ashore to lay their eggs a few weeks later.  So from March 1 to October 31, if you see something bobbing on the surface a few miles offshore, you may be able to see turtles mating, just as we did.  We saw 3 pairs within a couple of hours, and I think we could have gotten closer if we had slowed down, but we didn’t want to disturb them.
We didn't get a very good picture of the mating turtles, but you can see why it would be hard to figure out what they were until you were closer.
Hawk’s Channel runs about 2-4 miles offshore, so you are always within sight of land.  Boat traffic was light in both directions, so we only passed by other boats 3-4 times an hour.  Some of them traveled quite fast, able to make the same trip as we in 2-6 hours, but we don’t really envy them since they burn through a lot of fuel in order to do so, and probably miss seeing things like mating turtles.  We also saw a lot of fishing boats and dive boats going in and out at inlets, but they zipped across our path before we even got close to them.
Large boat headed south too
We were approaching Channel 5, one of the inlets into Florida Bay that can accommodate larger boats, so we had to make a decision about whether to continue on the ocean or whether to go into Florida Bay.  The wave heights had only gotten a bit bigger – 1-2 ft rather than the 0.5-1 ft we had been enjoying most of the day – so we would still be comfortable if they didn’t get too much bigger.  We still had about 4 hours to go, however, so since the waves were forecasted to get to at least 3 ft and were on our beam, we decided to head into Florida Bay through Channel 5.

The water depths in Hawk’s Channel had been 10-20 ft, while depths in Florida Bay along the AICW at MLW (mean low water) could be as low as 6 ft, according to our charts.  Since Lorelei IV only drafts about 4.5 ft and the tide was rising, we were reasonably confident that we wouldn’t run aground as long as we stayed in the channel in areas of lower depths on our charts.

The water in Florida Bay was calm and smooth compared to the Atlantic, and depths were 6.5-8 ft for the most part, so we were glad that we had chosen to finish our trip on the inside.  As we were passing under the Channel 5 Bridge, a fisherman in a nearby boat got a good-sized fish on that took his line was across our path.  Another person in the boat was backing it up to follow the fish, so we almost came to a stop for a minute or so until they could get clear.  It would have been cool to hang around to see if he was successful in catching the fish and what kind it was, but since we didn’t want to run out of daylight, we got underway again as soon as the way was clear.

We had a few somewhat anxious moments when the depths dropped as low as 5.2 ft at a couple of narrow passages in the channel, but since this lasted only a few seconds and then quickly got deeper again, we figured it was just a little sand shoaling in areas that are apparently prone to it.  The only other excitement we had was when a pod of dolphins came to play in our wake for a while, and we could see them very well due to the great water clarity and relatively shallow depth.

7 Mile Bridge was our landmark for nearing the end of our trip and we could see it for a quite a while before we finally reached it.  Once we passed under its tall span, the water got a little rougher, once again confirming for us that we had made a good decision to travel on the inside for the last few hours of our trip.  Once we were in the approach channel for Boot Key Harbor, the water calmed down again, making for an easy entry.  The channel through the Harbor to the Marathon City Marina mooring field is well-marked, so we had no trouble finding our way.

The City Marina does not accept reservations for moorings, assigning them on a first come, first serve basis when boats are actually in the Harbor.  Since we would be coming in after the office was closed, we were told to call back a few minutes before 5 pm.  If there was still a mooring available for our size boat, then they could assign us one at that time.  Fortunately for us, since many boats head north for hurricane season, there were 3 moorings available in the part of the field that can accommodate boats larger than 45 ft.  Even though we thought that our mooring would be in the first row that we would come to, we were confused for a moment, because one of the buoys marking the edge of the mooring field was close to that row and had a different letter on it.  We finally saw the ‘W’ that we were looking for when we looked closely at the first mooring ball in the row.  We were assigned to W-5, so then it was just a matter of making our way down the fairway until we found it.  Rob had no trouble picking up the pennant, passing our 2 lines through the eye and securing them before the boat even had a chance to drift back on them.  It’s so nice when we look like we actually know what we’re doing!

One nice thing about being on a mooring ball is that we don’t have to wait to make sure we are secure like we do when we anchor.  Since it would be getting dark shortly, we quickly deployed the dinghy and took Sasha for her walk ashore.  There is a nice park close to the marina, so we found a nice patch of grass for a Frisbee session.

We got all checked in at the office the next morning, getting our welcome bag, dinghy tag, and parking tag for our truck.  It was just a short walk to the storage lot where we had put the truck a couple of weeks before, and along the way we found another small park as a back-up for Sasha in case the one near the marina is too busy.

We have to make her take breaks when she looks like she's getting hot
