Help me with this puzzle.. Please if you can!

I really don't have the foggiest idea where to start with this, I keep coming back and coming back but I'm just at a blank!

Here’s The Puzzle then….

My mother was moving house and asked me ‘sort out’ Dad’s things. Lots of it has sentimental value, his old tools from his joinery days after leaving the Navy, a few books and some trinkets that caught his fancy at the time, but the most interesting thing was a tatty old notebook inscribed “Sam Elerry AB (Signaller RN)”.

Sam was my grandfather who I never knew, born in 1865 he spent most of his life at sea in the Royal Navy, first on square rigged ships and later on steam powered vessels, finally retiring to serve with a local shore battery on the South Coast. Whenever I asked Dad about him he just used to say he was an old ‘bunting tosser’ which I thought was a bit rude!

The book had lots of pen & ink sketches and columns and columns of numbers.

Towards the back was a loose sheet with what might have been a timetable of some sort. Not all the entries were legible and the handwriting suggested that Dad had re-written the times using the 24 hour clock.

There are some additional hints as follows:

06:37 00:52 00:52 03:45 06:37 04:37 04:45 03:30 10:45 03:45 03:37 01:30 03:45 06:45 06:37 06:52 07:00 00:52 10:45 03:45 10:45 06:37 06:00 00:52 10:45 00:45 10:45 03:30 03:45 07:50 04:30 07:45 00:52 03:07 10:45 10:45 06:00 00:45 10:45 04:45 00:52




I've got as far as working out that a bunting tosser is an informal term used in the Royal Navy to describe the sailors who hoist signal flags, as such I'm guessing that the times are Tide times?.. but meh where do I go from there

the final aim is to get a set of co ordinates in the form of degrees and minutes.
