Working on OpenCPN is one of my hobbies.

I am particularly interested in weather, climate, mathmatical algorithms and graphics.

I have recently begun an effort to produce a free software autopilot

My engine-free Bristol 27 "Alexandra" as of January 2014 anchored in the Phillippines.

Since 2017 I have been sailing the east coast of the USA. I continue to support opencpn and its plugins.

I have built a free arduino based anenometer, and am in the process of making a free depth sounder.

To improve my ability to develop free software for marine use, please consider a donation.
