So last weekend I committed some rather poor seamanship and weather
preparedness. (as an e.g. of what were many errors that no doubt belong in the sailors confessional: The exhaust
pipe on the transom is no longer hooked up to a muffler
. I've been meaning to get around to plugging it, but it hadn't been a problem in several weekends of previous sails
so I didn't bother. Last weekend, when there was some real wind
(forecast said 12 kn, wind
gauges said 16 with 20 gusts and a small craft advisory). Apparently when the boat heels over far enough the exhaust
pipe goes below the waterline. I discovered this when the bilge pump
went off and I saw a nice stream of water
flowing into the bilge
As penance for my poor seamanship and failure to look at the weather
, I decided to look into how often conditions are as squirrely as last Saturday.
I also thought it would be interesting to compare the sailing in the Chessie vs. Miami
and SF Bay
. So below are some nice histograms showing how often the wind is at certain speeds in different months over the past five years (2005-2009 inclusive). I reproduce nicely the fact that Chessie winds are more variable and that sailing is best done in the fall and spring. Furthermore, in general, the Chesapeake has higher winds than both Miami
and SF, which surprised me. It also surprised me how high of a windspeed one should be prepared to deal with in the fall months on the Chesapeake (15-20 not uncommon), which has me rethinking my priorities in terms of sail selection.
Without further adieu, enjoy the data presented below. If you want a chart for another US based port, just let me know and I can probably put it up in pretty short order.
