May 2015:
Is this Spring?!
 Click on Thumbnail
By May I hoped to be doing more sailing but the weather remained unsettled: on the 5th May we had a gale on the river (see photo). The unsettled weather continued during the month. When the weather improved I hadn't anticipated that a very minor operation would keep me off the water waiting for the wound to heal.

The Physics of Apparent Wind

Click on Thumbnail While not being allowed to do physical tasks, I've taken the opportunity to rework my discussion of "The Physics of Apparent Wind" which was prompted by a thread on the Swallow Boats Association Forum. It includes converting from apparent to true wind, properties of the apparent wind, and limitations on sailing faster than the wind! [pdf version - 900kb]
