actually it does 60 miles x 60 minutes = 3600 devide by speed 20knots =180 minutes
i think Simon meant distance devided by speed will give you time or you could use the 6 minute rule based on your average speed, remember though some tides will be with you and some against you so need to take that into account,as will add/subtract from/to the total distance to be covered, interesting passage plan posted think you would be better using turning bearings on well charted objects on the southern side of the Island as propellors dont give much drive over land.

oh bugger where is me reeds almanac must look up tables for Mars bar chomping , does it depend on height of eye ie the greater the height the quicker they go down ,a wild stab in the dark i would add 5 minutes does the same rule apply for sandwiches and if they are different types does this change the formula
best of luck with the predicted log

ok here is the formula and it does work trust me . take a piece of string 60cms in length at a ratio of 60:1 each cm equals one degree place string in mouth and hold ruler and string in same hand line up ruler on charted object
the height of the charted object in cm is equal to degrees look it up in the almanac tha tables are there this will now give you a rough but fairly accurate distance off said object, throw that one in when teaching the shorebased nav courses students love it , was shown that when first went to sea as a nipper, great skipper tutor on me first boat always stuck with me same as plus two minus two for recipricol bearings
regards Tim
ps going to boat show midweek as well not sure what day yet probably tues
might see you there.

A great deal of technicality went into our journey....
First bearing took us towards the Hamble area...then on towards Lymington.
We were slowed up a lot there but a tip off on the phone caused us to do 180 turn and head back for the Hamble River and the Royal Southern.
We got a minor award for our efforts.
Thank you to the esteemed Committee.
