Or if you were lucky enough to be sailing the whole time and just using the genset to charge batteries, how much would it use an hour. Its an Onan 7kw/1500 rpm.
Also what speed would you be hoping to make at cruising revs, and if you were passage planning what speed would you be hoping for under sail, I was guessing averaging about 7knots?
I sailed a brand new 49 (standard cabin), not the DS, but same hull different looks top sides, that's all, and very similar to the one you bought.
A good friend of mine bought one this year. Expect around 8 knots cruising speed average both on sail and power, but not much. Will peak higher if conditions allow.
The boats don't have an adjustable backstay, sail trim is somewhat down to basics, and we needed to close the sink valves under sail.
Overall a decent boat, no wood inside, nice showers, but finish is somewhat ...well....
Fuel consumption for that Yanmar is 1.5 gal/hr at 2000rpm, 3 gal/hr at 3000rpm and 5.5 gal/hr at 3800rpm.
Cruising rpm is 3400 and consumption is 4 gal/hr.
Your electrical consumption when sailing depends on use of electronics, but for fridge, auto pilot and basic ST60 material a good 80 amp per day minimum is required.
Congratulations on your buy.
