    Automated Sailing

    I'm not selling anything, woody. This is for a oceanographic sensor system development project.

    Yeah, we know about Saildrone; we’re rolling our own. Thanks for the ArduPilot lead.

    Automated Sailing

    The front page article (yeah I know, what’s this front page thing?) about the CYCA decisions governing double handed racing in the S2H got me wondering what is the present state of the art, off the shelf system for automated control of a sail craft? This for a technical development project I’m involved in for an un-crewed oceanographic observing platform able to transit from staging port to a work area, remain on station for several months, then return to shore. (There are a few such observing systems now available, but ours will have some unique characteristics). The pie in the sky control system will take in specified waypoints and make its own way there, adjusting heading and sail trim for optimal progress, including deciding when to tack or gybe. Is such a system commercially available? Thanks.

    WTF did they do to this J/125!?

    So what in SA’s “collective wisdom” is an appropriate amount to pay for this particular J/125? I’m tempted (double handed day sailing, weekending, occasional beer can and around the bay type racing) but as detailed here, this boat has issues, the 8 foot draft is constraining, and it’s a LONG way from home (NE) at the moment.

    Dick Carter design boats

    We attended Dick’s presentation at the Falmouth (Ma) library yesterday. Sandy Weld in audience as well. Dick mostly covered highlights from his book. Fun that his earliest sailing experiences (northern end of Buzzards Bay) is where we sail now. One anicdote from the Q&A session - in response to a question involving learning from one’s mistakes, Dick said his biggest failures were in navigation - sailing to the wrong mark because he didn’t read the SI’s carefully. Been there, done that.

    Nine foot draft in New England?

    Exactly why I dream of an after market lifting keel system. Restricted draft in our harbor (off Buzzards Bay) has certainly capped my searches of used boat listings.

    THE VG IS FOR PUSSYS - THE FIGURE OF 8

    For those of you into sea ice forecasting, here's a useful site based on satellite microwave observations: https://seaice.uni-bremen.de/sea-ice-concentration/ The NW passage is still socked in, but melting fast. The other way around is almost open now, but might run afoul of the Russian "toll booth" for passage through their waters.

    TF10 foiler... what could possibly go wrong!?.....

    Try $500,000, not 200k.
