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.

Rather keep mine on me trailer if its all the same

Predicted I think is the point here. Plan the passage then execute. You can predict your finish time taking into consideration tides stopages etc using the correct formula.

That would be a time trial then

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

[tim griffin]

would love to but am working , now talking about almanacs ever had a go of doing vertical angles with a sextant to find distance off a charted object
works with a piece of string and a ruler its true honest

Now you're talking about my kind on navigation. Remind me to you all with tales of astro navigation, great circles and the like. (He he - that'll keep them out of Pompy when I'm next on duty )

[The Jackeens]

Tried that once a good many years ago after a good session with the lads - nearly got mown down by a bloody great combine harvester - you just don't expect them to be out at 11pm do you?

[The Jackeens]

Beer n Crop Circles Very funny images spring to mind. No wonder the farmer tried to mow ye down for wreckin the harvest

Sir Martin of The Lower Bar has announced via telephone that the briefing is at 9.15 am.

(kinell ..that means an early trip in these wintrish conditions on Zeb )

Another one with his sextant out BTW is Martin.

Paul's whizzing something out on the pute.

[stingray]

Am i to late to enter !!!

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.

I will try all that after a few glasses of red Ta Tim

Ah darn it...we are going to BS at the weekend..

You can go again surely ??? (Go on go on go on )

[The Jackeens]

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.

Was it bumpy and are there any pictures?
