[QUOTE=Bene505;407573]... you could run the outboard at a slow, effficient rpm. I would think that adding some fuel bladders (and jerry cans) would decrease the amount of food and water needed, and therefore make a reasonable trade-off.
[QUOTE]

Thats a very interesting point, one which perhaps I shall have to look into. We've currently got just a 5 gallon tank, but are thinking of fitting 2 10 gallon tanks in the cockpit (and enclosing in a think plywood case to keep the direct sun off).

I might have to sit down and try and figure fuel vs food.. :-)

Another factor is how much you can/want to motor on windless days.

I think it is better to be conservative in your estimate than the reverse. If you get somewhere a bit early you have more time to explore. If your planning it so ambitious you will spend all your time playing catch-up and not enjoy it nearly as much.
Yes that definately the way round we'd prefer to end up, having extra time, not always being "late" - thats not cruising! :-)

You can compare your boat with similar boats. And if you don't find your boat like that you can add it there.

It's going to be a really really large passage on your boat..you're leaving from England? have you decided on a route yet?

You will, in a boat like that, probably average 4 to 6 knots, with some 11 knot peaks on waves. That is a looong pasage indeed...visit Portugal...it's wonderfull


Good luck...
And finally I'm senior enough to post a like to a possible route we're looking at:

Consider going Bermuda-Azores on the way home. The non-stop Great Circle Route may be a bit shorter, but it takes you through some potentially challenging patches and makes for a VERY long leg on the Atlantic crossing.

That is, unless you have a special interest in the Flemish Cap!

With an assumed average speed of 3.5 kn (daily run: 84 miles)
We can do the route shown previously in just under two years with a laziness factor of 2.3 (ratio of sailing:not sailing)

If I drop down the speed to 2.5kn (daily run: 60) the route can still work, but with a laziness factor quite a bit lower 1.4.

Now there's another question. What "laziness factor" have you sailing with ? With my current thinking, even as low as 1:1 would seem fairly reasonable, if I think sail for a week, spend a week in a place...

That sounds a much better plan, just adds 220 miles.

Flemish Cap... yes... doesn't sound inviting, remember it being where the boat in Perfect Storm was fishing when it all went a bit wrong!

Chibb, just curious ... why is one of your legs along the south Brazilian, Uruguayan and Argentine coasts planned as an offshore leg with a stop at Trindade? (at least it looks like Trindade- the map is garbled on my screen). Is it on the way down or back up that you plan on going offshore? Also, what months are you planning on going down the coast? There are better times in the year to do that stretch, although north of Rio any time of the year is going to be fine with a minimal amount of weather watching. And by the way, great choice of cruising grounds!

After heading across the pond from england, to Recife Brazil, the route goes down the south america coast. Plan is to arrive Recife in Start October, and to leave Argentina by End March the following year, heading offshore, via Trinidade/Martime Vaz back to the northern side of south america, exploring till around the end of the hurricane season in October, then up into the carribean, then eventually back across the pond.

The offshore leg, which as you suggest correctly passes Trindade/Martim Vaz on the way to the carribean was to avoid fighting the Brazil current which appears to run down the south american coast, and to get out into the possibly more favourable winds around the high that centres between africa and south america.

This part was also shown in the "Sailing ship routes" chart.

Any thoughts on this theory?
