Re: Waypoint datum - you can be too accurate!
Wholeheartedly agree with you about the accuracy of waypoint data and the differences between WGS84 and OSGB36, especially for passage planning. Remember that we can now fix our positions on the geosphere much more accurately than the original data from which the charts were drawn !!
Perhaps my earlier query was obscured in the maths - but it was a request for Stephen to clarify how data should be entered in his internet waypoint database - should it be:
a) Degrees - Minutes - Seconds - Decimal Seconds
b) Degrees - Minutes - Decimal Minutes
The form implies a) but most data is published as b).

I'd rather be sailing . . . . .
