    A blank canvass!

    Picking up the thread, propose (subject to discussion/agreement):

    - Departure from Needles or Bembridge ledge
    - Destination Cherbourg
    - Goal: Minimum logged miles v rhumb line distance
    - No use of PC or modern aids for passage planning
    - No use of GPS or electronic navaids for crossing
    - Echo sounder and log permitted
    - Radar permitted for CA only
    - No engine (unless becalmed?)

    Count Amaya in! Dates to be decided. Should we make it neaps or tatties?

    I'd beg to differ on one of the objectives ..

    I dont think distance v log is relevant - all one really needs is arrival closest to planned arival time.

    The shortest duration crossing may very well NOT be the shortest distance.

    The only complication here of course is boats quoting a later arrival target, and jilling around to kill time - but then that's what rally crews have to do, so maybe it is valid.

    Ok Iain, no problem with this.

    When do we announce our arrival time? I suspect (like last time) that boats will leave at different times depending on crew commitments etc so not feasible to say be in Cherbourg at 6pm Saturday or whatever.

    I'd prefer to call SWMBO or a nominated contact at Bembridge and for them to post my ETA.

    Trouble is I can pretty well guarantee arrival time by allowing plenty of spare time then wasting it all within sight of the entrance.

    Also arrival time will be very heavily dependent on wind / weather which can be difficult to predict in advance

    How about predicted v actual distance?

    I'm going to be difficult here

    How would you measure actual distance? The problem is that the expected accuracy of the log (or mine at least) is much less than the sort of differences in distance. So for example a 10 degree error in course only represents a 2% increase in distance - and my log is not that accurate

    That's the point - could you predict the actual log reading, given that you would (of course) know the error?
