I’m thinking of adding furling jib on my N6.0na. Is it safe to use Harken 435? (That is the one that I have) or should I buy Harken 436. The Harken website suggests that 435 is for catamarans 18 feet and smaller.

Also, I will be flying a spinnaker.

Anybody have any experience with those? I would appreciate any input.

Thanks

Kris
