CD30 Cutter (Lack of support)

[Greg Vandenberg]

Can anyone explain to me why the CD30 when riged as a cutter has no noticable back support for the staysail? I have been cuirous if the rig design could be applied to the Carl Alberg designed Alberg 30.

I have wondered the same thing about my CD30. I can only suppose that it is strong enough the way it is designed. However, I have thought that if I were to do a lot of downwind sailing in strong winds with a larger sail on that stay, that it might be advisable to rig some runners. But I don't do that kind of sailing and it has worked fine in all conditions I sail in. I have concluded that if it ain't broke, don't fix it!

I'm primarily interested because I want to rig a stay just inside the roller furling headstay so a working jib can be riged for better windward capability when the genny on the headstay is furled. Those dam roller furling gennys don't set very well when rolled to 100%

The mast section is plenty robust to withstand the staysails pressure, which is mostly side to side anyway. Runners would be a "belt and suspenders" approach if you were in the trade wind routes for a month at a time, but not in normal open water sailing.

I have a 140% Genny on a Hood LD roller/furler. The sail has been made with a foam luff sewn into place so that as the sail is furled, the foam causes more material to be taken out of the middle of the sail as you furl it, thus giving a decent shape up to probably 30%..certainly 90%.

I have also installed a 12 oz. storm sail with a wire luff. This I raise using my spinnaker gear. The storm sail attaches to the same deck fitting that the spinnaker uses, and this is located about 6 inches behind the roller/furler drum. I installed two line stoppers on the mast so that the genny halyard and the spinnaker/storm sail halyard use the same winch. I can get the tension set tight enough so that there is very little sagging of the wire luff in the storm sail. Incidently, I also do this with my yankee, although the genny works well in the same winds that I would use the yankee in. It just provides an alternate sail in case there was a problem with the storm sail or the genny.

Cheers!

Thanks Larry. Thats a real good idea! The wall thickness on the Alberg 30 mast is a little over .125 (1/8") There is a lot of concern in the A30 camp that there is a need for running backs because they go hand in hand. I think the rig won't feel a thing from what I'm hearing. I have one question...Is there any chaffing from the spin halyard rubbing on the furled headsail?
