After a reasonable tear appeared last year we replaced our main using a local/Yamba sailmaker (Scott Hinton, aka Scooter Sails) as we knew him to be very experienced and honest. We discussed a number of choices and then went with hydranet on the basis that it wouldn't cost an arm and a leg and it would last a long time. To minimize the cost, most of the cutting and sewing was done in Sri Lanka and then Scooter did the final fitting. Scooter's service through the whole process was excellent, first class...and we're now very happy with the mainsail.
We're currently thinking about replacing the furling genoa as well. It's the original, factory Incidences dacron and still serving our cruising needs, but the stitching's been repaired several times now and it's stretched around the 'window' and showing plenty of cracks. When we do replace the genoa we'll use Scooter again...and in fact we're waiting for his estimate now. The material recommended for the genoa was not hydranet, but unfortunately we can't recall what it was...argh! Scooter's currently racing overseas and we told him we were in no rush so we'll have to await his return for any further comments here.
We wouldn't hesitate to recommend Scooter (Tel 0418662889) to anyone in this region, including the OP. We don't know whether he could take on the work with everything else he's got on -- His business is well established and successful, but his true passion is blue water racing and he is called upon regularly as professional crew in races all around the world -- but he won't take the work if he can't do it...and his opinion would certainly be worth having in any event. There would be little about blue water racing that Scooter hasn't experienced or doesn't know and understand...and he's a nice guy!
It's probably stating the obvious, but to be complete we should note that our sail choices were not performance driven. Our priorities were longevity and value.
