I should probably put the tack line through my spinnaker pole - just trying the sail out for the first time yesterday.

Re: Video of test of my $200 eBay asymmetrical spinnaker

Ah yes, flying it off of the spinnaker pole should be even better. I haven't had a chance to try that yet (I'm still in the process of rigging my boat for a spinnaker pole).

Yes, that will work, though a longer extension would be better.. also your pole butt end track needs to go pretty low on the mast, many don't. It also complicates the gybe, needing to switch pole sides (remember the earliest AC series with A sails??) I suppose you could lash the pole to a bare forestay and not bother, but it does take away from the relative simplicity of the A sail on its own.

There are some pretty neat deck mount sprit kits out there now..

Are there any in particular that you've had experience with and would recommend?

Do you think the stresses would be too great for a extendable whisker pole? I have an old Forespar 11' to 18', button-type (not the flimsy twist type) with pole diameters of approximately 1 3/4" and 2 and 1/2". (my spinnaker pole is a 3" diameter 12' pole). It would not have to sustain the same compression forces that a traditional spinnaker rig would exert.

You can see it in this wing and wing video:

Sprit kits:

Two friends recently installed this one on their boats: Looked pretty good. The second made his own bow roller mounted support, using a velcro 'clew strap' to hold it into a bow mounted cradle.

I think the lift forces can become significant.. many A sails have more area than the symmetrics. My son put a sprit on his Ranger 29 (homemade from a pole section) and added a bow eye in the stem with a dyneema 'bobstay' to deal with that. The Selden kit pole is pretty beefy and is cantilevered from 4 or so feet back on deck.

Re: Video of test of my $200 eBay asymmetrical spinnaker

I've got to get an A sym. Too many days drifting with 5 knots of wind is just bad for a sailor.

Re: Video of test of my $200 eBay asymmetrical spinnaker

there is no advantage to using a standard "J " length spinnaker pole on an asym. the idea of using an asym. for cruising is the simplicity of not having to use the spinnaker pole. if you are going to use a pole then use a standard chute. an over length pole will help but then the bow pulpit will be in the way to get low enough. adding a sprit makes a lot of difference and get the sail more forward to be away from the mainsail. also makes a jibe easier with inside sheets

Re: Video of test of my $200 eBay asymmetrical spinnaker

I'd also make sure that your asym sheets don't go over the boom like that, just asking to get it all tangled up during a gybe.

+1.

Keep the sheet under the boom. An accidental gybe would not be pretty. (not likely on a beam reach)

On a beam reach the tack should be be near the pulpit. Watch the shoulder of the gennaker, that is where it should curl.

Great to see the mainsail deployed - very wise.
