I think the limiting factor may be the size of the hole at the edge of the center board. At least on my centerboard, there is a hole crossways, i.e. oriented as the hole for the pin; but there is also another hole, smaller, which runs from the aft edge of the center board perpendicularly and intersects with the crossways one. The pennant enters the smaller hole and can push out either side of the crossways hole, so one can put a swage fitting on it.
This means that a bigger pennant requires a bigger hole. And there is only so much Centerboard thickness to work with. So I think thats the real limit.

Hello,
What size wire do you use for the centerboard pennant. I originally ordered the replacement cable from Tartan, but it seems it is only 1/8". That has a working load of 340lbs and a breaking strength around 1760lbs -- so, it should be plenty. But is it worthwhile to go up to a larger size ?
At what point is the diameter too big?
I know some people are experimenting with dyneema, but I am going to wait to hear how that works out before making the switch. Among other things, last time I got hauled out I couldn't drop my centerboard because a bunch of mussels, barnacles, or other hard, pointy things started growing in the centerboard trunk and actually jammed the centerboard in place.
If those things started scraping on my centerboard pennant, I think stainless steel would fair better than dyneema.
