Found a much smaller garbage patch in the SW Caribbean recently. We were about 100 miles from the western end of the San Blas Islands in Panama and ran into a large region of sargasso weed and plastic. Took us several hours to cross it. Apparently the currents from the east swirl here and plastic comes from all over the Caribbean until it finally is carried west along the coast of Colombia and Panama. Nasty looking to be sure.
Back in the water in Grenada - with new main and #2 and cockpit canvas (Santa came early). Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
