In Topic: Why do multis (supposedly) not point as high?

^^^ Most cruising cats are underpowered most of the time (maybe all the time with careful owners). Typically they're going to find their upwind VMG at pretty broad apparent wind angles because there isn't enough power in their rigs. Efficiency (eg lift:drag) plays into it but I think it's secondary to lift for the "typical" cruising cat. Adding more sail power adds cost and risk beyond what is ideal for the service.


FWIW, my experience on my 40ish foot cruising cat with good foils is that my upwind vmg v monohulls improves as the wind gets up as long as I'm willing to sail nearer and nearer the edge of stability. The thing is, sailing like that isn't safe or relaxing.

Oddly the 5-day outlook is only for new lows. Try the 2-day:

Are folks still getting images direct from the LEO wx satellites at sea? I haven't seen as many of those eggbeater antennas as I used to.

From a delivering wx data to folks perspective I've never found it harder to send to a winlink.org address than any other.


Just FWIW, even if you don't have band privileges, for raising help on SSB 14.300 is worth a try.

I also look at the wfax charts to get a better idea of the frontal activity, and any early-stage tropical low-pressure systems, but the gribs are my main source of info.


Often, particularly in the mid latitudes, the RAIN rate on the models will show the fronts / trofs [sic]. If I can get it I like to see the lifted index too.


When we started cruising wxfax and fleet code forecasts were worth jumping through hoops to get. Over the years AVN / GFS has gotten to be much more useful to me and completely replaced them.


IME, the models are not skillful near the equator and the wx faxes there are the same bad data but older.
