Terminology for these sails
is sometimes confusing so my understanding is:
Code 0 : Large essentially flat cut sail for upwind work in light winds
Schreecher : can be either a Code 0 or Gennaker
depending on which country you are in.
The Code 0 apparently has very high loads so you would want to validate whether the bow sprit will take the load. I think the rig itself is pretty strong.
is not a Code 0, it is more fully cut than that. It works very well with apparent wind
~50deg through to about 130deg but is not very good at deep angles. Not sure what TWA that would be. The lighter the wind the higher you can sail. In a nice beam reach or closer it is great sailing.
a. Use it on the bowsprit
, or swap it with the jib
on the standard furler?
-- I would use it on the bowsprit to give you the extra size. You should be able to use the SPI furler, The new Facnor ones have a quick release as far as I know. I am getting a Selden which does have a quick release pin.
b. dacron, nylon or Hydranet?
-- Typically these are nylon but I don't have experience of the others.
inside or outside the side stays?
-- Outside, rig the same as the spinnaker
. I take the sheets between the forestay and gennaker which makes tacking a little harder but it eliminates the possibility of dropping the sheet under the bow. As we only have the one winch
(port aft) your control of the lazy sheet is not great when gybing. Worse case you furl and unfurl on the other tack.
d. Mount an extra traveller or use the spi blocks at the rear?
- Rig as for the spinnaker
using the standard turning blocks.
e. Continuous or one-line furler?
-- Continuous. I am just replacing my drum furler as it is near useless. It needs too much line for the drum (unless you fit a big unit) and continually jams both furling
and unfurling. With the right technique you can minimise this but it always jams at inconvenient times. You either run out of turns when furling
in strong wind or you put more turns on and then it jams.
f. What increase in performance to expect? Is it worth the trouble and money
I have not really measured this objectively but you certainly feel the difference in the power. As you have the assymetric to cover all the off wind angles you may not get as much benefit. That said I am about to get an assymetric to complement my Gennaker.
