Re: Telltales and such
I have telltales all up and down both the leech and the luff of Rowan's fores'l. You can tell an awful lot more about the flow and whether you're keeping it attached all the way across your sail when you've got plenty of things to look at to let you know what that invisible air is up to The masthead pennant on the mizzen mast isn't particularly useful at all, except to give a general sense of where the wind is coming from--and to display my personal worm-drive burgee, of course.
Especially when you're sailing fast enough to change the apparent wind--by adding the vector of your forward progress to the actual wind--the only thing in the world that matters is how the airflow is striking the sail. Which way the wind is blowing other than relative to your sail is kinda irrelevant to some degree. And tiny changes in sheeting angle or twist or camber by tweaking with things like outhaul tension or downhaul tension can make marked improvements in your sail's power--but only if you can see what's going on.
The best (and cheapest) sail telltales you can make yourself in a jiffy with bits of the magnetic tape from inside a busted cassette. Just thread a length on a sail needle and stick it through.
I don't really have any good pictures uploaded to illustrate what I'm talking about, but you can definitely see them in action in that big Barkley Sound video I posted.
Amphibious Macroplankton Oughtredia doublendus
Mostly found frequenting the littoral and estuarine zones in the southern half of the Salish Sea, though sightings have been recorded both north and south of this area, and occasionally, but rarely, inland, in freshwater environments. This species lives on micro-brewed beer and dutch-oven biscuits,and displays brightly colored nylon and gore-tex plumage during the rainy season. Approach with caution!
