Yup! October of 2015, as long as everything goes to plan. If we have a really uncommonly early and nasty hurricane
season, that would stop us from getting there. We'll be coming through the Caribbean
in late August.

Yeah, there's something like 220 gallons of fuel
and 350 gallons of water (or thereabouts). The 54hp Yanmars were burning a little over 1 gallon an hour and providing around 7 knots of boat speed (I think this was 2500 - 2800 rpms). I can verify this more after our delivery
, as I'll keep good records for fuel
The new boats will have the 57hp common rail Yanmars, which might be even more efficient (I'm expecting .85 - 1 gph @ 7 kts, but we'll see). All of this is while running on one engine
, btw. And dependent on conditions.
So let's take a range from 6 kts made good to 7 kts made good. At the more conservative burn rate for the 57hp Yanmar
, you'd hope to have anywhere from 1,320 nm to 1,540 nm in range under motor
. At .85 gph, you would have a range of 1,552 nm - 1,811 nm.
Either way, the 220 gallons should net you a little more than 9 days of motoring, 24 hours of day.
I wouldn't want to carry more diesel than this, to be honest. That's enough to get you through some serious doldrums to the Marquesas
, or to last an entire season in the Bahamas/Caribbean without needing to take on fuel (unless you insist on a timetable, rather than waiting on wind).
The water tanks
on the SF50 are much larger than what I need for regular use. If I'm sitting at anchor
, in clean water, I'll top them up with the watermaker
so I don't have to run it often, and be able to rinse down the dinghy
, water toys, myself, the deck, etc. But if I'm on a passage
, I'll keep them a quarter full and run the watermaker
more often. Just because the capacity is there doesn't mean I have to use it. Empty tanks are floatation and speed.
Incidentally, that's how I now think of empty staterooms. I used to think I HAD to get a 3-stateroom boat with an owner's hull. I couldn't imagine needing four staterooms, so it felt like a waste, which made me think of other uses for one of those rooms. And then I sailed around on a FP that had five staterooms. There was just one person living aboard! And I realized that empty staterooms are a good thing. It's space you aren't using up on other stuff. There's no weight there, just floatation and speed. It got me over the feeling that I needed to maximize usable space just so I could fill it with "stuff."
Also: Staying aboard the SF50, I found the master's accommodations to be as generous as any owner's hull. Many owners' hulls have a lot of walkway with a weird bench there that I never understood. Would you ever actually sit on that thing? Why? There's nothing to look at or see down there. So you end up with a stateroom in the stern and a head
in the bow and a lot of hallway between. I quickly got over the idea. It was a big hang-up for me, and it kept me from looking at a lot of other good options in catamarans (a lot of 4-stateroom boats I dismissed as "charter" boats that I now realize would have suited me perfectly).
