I regularly single hand an asym
spinnaker on my 40'. I was using an ATN tacker but after making sure the
anchor roller attachments are beefy enough have re-rigged the tack
line through a block from the bow. You have to make sure the bow is reinforced properly though! There is more force than you think hauling on that tack
line.
This arrangement seems to work really well and reduces the time spent forward sliding the tacker over the furled genoa prior to hoisting the
spinnaker.
I have a sock for my
spinnaker as well and have found it simple even in 20ish knots to blow the tack and dowse the
spinnaker in the mains lea. Light wind allows dowsing without blowing the tack.
I will say I modified the dowsing
line to go through a block which is fixed to the foot of the mast prior to hoisting the
Spinnaker. This keeps the
line from getting fouled when you need it most!
As for jibing the chute I have the safety of the boom brake to assist with the movement of the main and I have yet to have a problem jibing the chute forward of the forestay (I might want to knock on wood).
