    Re: Life raft questions - knowing only GHA and sun's rising or setting
    From: Tony Oz

    Dear Ed,

    You said:

    ...you could also estimate at sun rise or set the sun is six hours local time but that depends on your latitude and time of year. So this is subject to some big errors...

    Such table (to estimate one's latitude from daylight duration and date) is included in the Harold Gatty's Raft Book - with the auxiliary interpolation tables. This table also lists the LMT of sunrise/sunset along with the azimuths to those points. Was all this obsoleted on modern life rafts?

    Regards,

    Tony
