Using Gennaker with a top down furler

[DougM]

I have a nearly new North gennaker that I rarely use mainly because I am sailing shorthanded (not solo) with inexperienced crew at times.
I am wondering if anybody has converted an existing sail like this to use on a top down furler. I am familiar with the hardware needs (and cost). What, if any, modifications need to be made to the sail itself?

As long as the sail fits between the rollers with acceptable shape, not much. Most sailmakers will sew in area Velcro around the clew to help keep the sail rolled up. But that’s about it.

The sail will have no UV protection, so be sure to take it down when you’re done .

And depending on the furler, an adjustable tack line can add or reduce shape.
