Shot jib on tall rig?

I am looking at a used Catalina 30 that has a standard height jib installed on a tall rig with the head hoisted to the top of the mast. I was told this offers good visibility under the jib, but have a concern about the center of effort being higher than originally designed. Has anyone else done this, and should there be any issues with it? Thanks, Jeff

Center of effort is also being move aft which will give you more weather helm.

You can add a pendent at top of sail and keep foot at normal height if you like.

The sail could be cut to be installed on a furler, hence the extra height above deck. Is there a pendant at the tack? That could be the spacer needed. On our '84 TR, the Furlex 200 (with a 6" stainless extension link) puts the tack just above the bow pulpit and lifelines. I like the visibility (and probably don't have the experience to reckon whether the sailing characterisics are the worse for it...).

I have a standard rig, not a tall rig. But I also have a high cut genoa on a ruller furling.
If your sail is indeed cut for a standard rig, then your sail area is somewhat smaller then it would be on a tall rig. This should help to compensate for the higher hoist of the tack.
You can always install a pendant as previously described to lower the head of the sail.
The tall rig model is only 2 feet higher in length of the mast, but it naturally creates more weather helm effect.
If you are not carrying as much sail area as the tall rig normally specifies, then your weather helm should be LESS the then typical tall rig model C 30's.

I wouldn't worry too much about weather helm, unless it feels severe.
But the mormal way to reduce weather helm is to reduce sail area, so
your sail area being reduced should only help you, not hinder.

I used to have a 28 foot S 2 sailboat, & when a rigger placed a pendant at the foot of the jib to raise it so it would help the furler operate, it did increase my weather helm. Lowering the head of the sail should have the opposite effect.

Good luck & trying out different cominations of rigging won't cost you much, other then time & effort until you find the right combination. I never stop tinkering with my boats & making improvements, albeit small ones can create big gains & be very satisfying.
