Typo

Thanks for validating my calculations, but I took the short cut. Figured a typo was made, added one "0", and came up with reasonable numbers.

Hi,

I am assuming there was a mistake made with the numbers quoted for that journey.

In the meantime according to my calculator 350 US Gals for 60 NM Travelled at 9 kts makes an average consumption of 5.83 US Gal per mile, this can be expanded further to take the whole capacity and divide by 5.83.

4000 /5.83 =686 NM .

This seems to be a very small range for a 60ft Trawler Yacht.

The following info comes from the Sea Spirit Owners Blog which is linked to in his signature.

6) When we're trying to cover a larger distance in a shorter time, we often choose to cruise at 9.5 knots, burning around 9.5GPH. I can see from my chart that if I slowed down only 0.3 knots from 9.5 to 9.2 knots, I would lower my fuel usage from 9.5 to 7.5 GPH or 1.2 NMPG. While I don't usually think too hard about fuel prices, if range were an issue, this would be worth doing. It seems that this is right around the point where fuel usage goes through the roof without much improvement in speed.

Bummer

Only really big ones!

At 53 gallons per hour that little Lugger must have been spewing fuel all over the place, that is about 3 times what it can burn at full rated power output.

You think he would have mentioned that.

Cape Horn suitability for you

Dear Cruising4Fun
I own a cape Horn (no not for sale! but in her 1st major refit after 10 years and 30,000nm include St Lawrence to Seattle via Panama, and then down to NZ via Sth Pacific, all on her own bottom). She is 81' all steel, called Columbus (was Wright of Passage). I will try to answer any questions. I am a huge fan of the vessel, and have been in most sea conditions in her and happy with her performance, being very suitable for our needs. Well maybe 2 extra knots... She is quite different to the dashew style mentioned - which is narrow so terrifically efficient, but Columbus is easily pushed through the water with her hull profile, and while not as super efficient, is fine, and has huge volume. I'd also inquire carefully about performance of skinny hulls in your expected sea states, as I love the comfort and confidence our Cape Horn provides in the gnarly weather in NZ at times. (We're crazy enough to boat year round down under). All the best with your search. Campbell.
