Well just talking about the wing part, most of what we use is probably equal to 3/4oz spinnaker cloth which has an actual weight of approx. 0.9 sailmakers ounces which is ounces per square yard. The lightest Contender CZ cloth is 1.9 sm oz and the next is 2.1 sm oz, so give or take about double. Now we're only talking about 4 or 5 SqM generally so the actual difference is not huge but those non-nylon/polyester cloths are never going to be a similar weight. It will come down to longevity and feel for most people...
That would only be around 140 -200 grams weight increase in a 5m.
It is very little but very spread out so the difference in inertia can probably be noticeable in handling?.
A 3.3kg 5m as referenced by the poster above is more than a 200g weight increase. That's probably more like a 500g increase over standard ripstop. That weight makes it a lot heavier than most 6m wings. Luffing will definitely suffer on a wing this heavy.
its going to be hard for Reedin to get many people on board with that. I'm sure the feel is much better in certain aspects, but given how hard it is to demo gear, I'm sure many people are going to get hung up on the weight.
You're arguing a negligible weight gain +/- 500g over a higher performing shape with increased longevity.
Very few people will ever gain a performance advantage of a super light wing then following that - it'll need replacing much sooner as it'll stretch and bag out very quickly.
For the record, going by the info in this thread - If you compare the Reedin to the truly lightweight wings we are talking about over 1000g difference (1300g if compared to full Aluula Glide). Thats not negligible - it weighs 75% more than the lightest wing on there!
I can see areas where a wing like this could accel, but there are areas where that kind of weight difference is meaningful and would absolutely be noticed. Adding a couple lbs of weight to a wing is definitely going to impact its ability to luff. Having to handle a wing that drops while luffing sucks. Even some of the design contributors have stated they prefer the lighter ripstop construction for some disciplines of winging (surfing for instance).
One interesting comment I saw said that you can ride this wing a bit smaller than a normal wing and generate similar power. If thats the case, maybe we should be looking at the weight for the next size down for a true apples to apples comparison of power/weight. For what its worth the 4.7m weighs 2.90kg.
A valid point I concede re weight, but a really important factor which has been missed or cherry picked. All these weights are dry. I've only had a few sessions where I've managed to keep my wing dry for extended periods be it waves or getting in the water, and I can assure you most are in the same basket. The moment the Dacron and ripstop get wet, well.... hate to tell you, you've just gained a hefty chunk of weight, the frame more so than anything.
Reedin X-ply is hydrophobic as is most laminates, water will bead and peel off. Spinnaker ripstop will absorb water, no matter the weight, no matter the layup, that's the nature of it, dacron the same. I know this from years of sailing and industry. The easy one here is a wet spinnaker is heavier than a dry one, even if it's lapping at the surface.
So what alternatives do we have?
I can't speak for Aluula as I'm not super knowledgeable over it, but that being said. Today I saw a photo of an RRD wing with an Aluula frame and laminate wing. I would say this is probably the next logical move.
