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).
