Am new to sailing, wanted to buy a used asymmetrical spinnaker
(my understanding, happy to be corrected if in error, is you get a roughly 80-150 degree working window with asyms, increasing slightly if used in tandem with spinnaker
pole for closer to ddw).
So was wondering: How does one size an asym for their boat
? Any considerations and cautions thatta newbie who don't even know what he don't know should learn up on?
Been hemorrhaging money
inna boatyard here in SF Bay
(bought it in Stockton of all places; asked broker
was in the Witness Protection Program; not slagging on Stockton, just not the exact place I'da spected to find a Skookum sailin fishboat). So apart from alla spendy must n oughtta haves in the sailing realm, boat's gotta answer for commercial fishing
, too, (and that's had alla its attendant vexations and cost overruns), so:
Think I'ma have to be content with just one specialty downwind sail for light airs for now to go with main, mizz, 110 Yank and staysail (purty heavy dacron; 10.2 oz. for main n mizz; 9.8 for headsails); oh, n gotta storm trysail, too.
Any thoughts or gentle (or not) corrections on my understanding of what follows is greatly appreciated. Tx. in advance.
My specific question: Mainmast measurements: I = 50 feet, J = 18 feet. Is luff length of asymm the determining factor? I.e. You want it maximized on your masthead rig so's it uses all available area but leaves a body room to see where you're going and keep sail outta water
and room for sock at top? Not just sure how to proceed, so any that wants to put an oar in the water
, much appreciated.
And is there a substantive diff betwixt an asym and a gennaker
? Or is it marketing
And weight/density? Was reckoning 1.5 ounce cuz boat's a tank -- 40 gross tons, but happy to be enlightened otherwise if lighter might answer.
Seen an asym online I kinda warmed to with a luff of 51'6", leech of 46', and a foot of 26''; gotta ATN sock, no sheets
, 1.5 oz. for 1.3K. That sound about right? Or is it high or low? No idea, really, tho comparative to other listings seems sorta economical for what it is.
Sorry so clipped, tried not to over-indulge my inner-logorrheaic. As Mark Twain once said upon closing a letter, I'da made it shorter but I run outta time.
