A few Bahia ????

I have a few questions:
What should my SOG be if no tide or wind with yan 40s:
1500
2000
2500
3000
Along with that, what should my fuel consumption be?
Don't know my props! Learning as I go.....

If I were to add a generator, what would you suggest? Seems there was one in there before! Port side
Have a mermaid 16,500 in port aft and Adding a 2nd to starboard aft... Run off 110. Still have originals in the forward cabins.

Thanks.

John I will answer this one here although I cannot really give you the answer you wish.
We also have twin Yanmar 40 with two blade variprops.
Do you have the Yanmar manual?
When we were delivering the boat back from Tahiti to New Zealand we found the fuel comsumption graph in the manual to be fairly accurate at the varying rpms and could therefore ration our fuel quite reliably. On that journey we had no mechanical speedo, only SOG from GPS data.

I do not wish to quote SOG vs rpm vs fuel consumption. It is not something we take the time to consider other than more revs=more speed=greater fuel comsumption and less revs=slower speed= more economical. We have not seriously monitored speed vs ?? and probably never will.

There are so many variables such as full water and fuel tanks vs empty. How many cases of wine aboard? Stocked up for two months cruising or just a weekend? Then there is the difference between individual boats. Genset, watermaker, hookah dive compressor or dive tanks, dinghy, outboards, kayaks, tools, washing machine etc etc. Fixed or folding props. Liveaboard or not? We do not have a house in NZ so there is a whole bunch of stuff on board that would normally be in the shed at home. And we all know that weight makes such a difference to the performance of a multihull.

Cheers
Lisa
