It is interesting when you are trying to find an anchorage on one of these islands. From the chart and wind direction it looks like there should be no wind waves since they would have to 'bend' (refract) much more than 90° around the point of the island to get you - but they do.
I agree also about the effect of swells. In deep water you have quite long easy swells but when you get close to shore the wave length shortens and the waves get higher.
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.
