Recently purchased this ATN
Spinnaker Sock / Sleeve for our
new boat but found that it does not fit. I have pasted ATN's description below.
Asking $450 (half of new price), plus
shipping.
ATN:
Single hand any
spinnaker, reacher,
gennaker, MPS, screecher or mizzenstaysail up to 15,000 sq. ft. (Mega
sloop Frers/Huisman 156' 'Hyperion'

High-tech, ultra-light Kevlar Hoop matches shape of the spinnaker and will not warp under load

Single control line led through separate sleeve eliminates fouling

Contrasting visual reference stripe

Wire pennant with swivel at
head of spinnaker prevents sleeve from affecting sail shape by allowing the sleeve to accumulate on the pennant

Mesh construction allows sail to breathe, so that
sails dry quicker, even while stored
