My understanding is that the current sail cloth specified for the Laser sails is somewhat unique so that is likely to increase costs since it requires special production runs just for Lasers (based on what I recall from previous discussions here). The tighter specifications also mean that it is likely there is more waste/expense for sails that don't meet the standards which means more cost in the manufacturing process (ie our strict one-design process probably means a certain number of sails get rejected for fiddly reasons that don't really make a difference in terms of performance or longevity). We don't really know all the costs that go into the distribution/supply chain but here is my attempt at taking a guess starting with the assumption that building a sail in Asia costs only $100 in materials and labor (which I think is likely to be a little low). (all amounts & percentages are just a guess.) Hypothetical Laser Sail Cost Class Legal Knock Off Manufacturing Cost $100 $100.00 ICLA Class Royalty 30% $30 $0.00 ISAF Royalty 30% $30 $0.00 Designer Royalty 30% $30 $0.00 Shipping 10% $10 $10.00 Distributer Mark-up 30% $60 $33.00 Retailer Shipping 10% $16 $0.00 Retailer Mark-up 30% $44 $0.00 Total Retail $320 $143 Granted, I'm just pulling the percentages for royalties, shipping and markup out of . . . thin air but even with these assumptions a class sail is over double the cost of a knock off. It is likely that there are other costs in the distribution/supply chain that I didn't even consider which would likely add to the cost of the class legal sail compared to the knock offs like. For example, is a 30% markup on a low volume item enough to stay in business? Also is the percentage and placement of the royalties in the correct sequence? It's possible that some or all of the royalties might be structured more like VAT and added in several times during the process or calculated later when the cost is higher. I also have no idea what, if any, the effect of taxes and duty might have on the cost for either class legal or knock offs. I was just a history major and math and finance aren't my strong suit so maybe someone else has better assumptions. . . Taking a quick look online it looks like a North Class Legal sail costs $565 An APS practice sail that is " heavier" 3.8 oz cloth runs $179.95. They also advertise a 4.5oz "training" sail for $454.00 which is pretty close to the class legal sail price. Could it be that the heavier cloth is a less common weight that increases the total cost? The Intensity sail lists for $199.95 (on sale for $179.95) and is made of a "firmer dacron" "3.7 oz polyester". Given that Vanguard was the first Laser manufacturer in the US to not go out of business (if I recall correctly) I kind of doubt that anyone is making a huge profit on Laser stuff. The retail price differential of the practice sails compared to class legal isn't that far off percentage-wise from my guess above. While I'd like to see a cheaper, longer lasting sail just like anyone else but when I think of all the other areas where companies are trying to rip me off I can't that worked up over the deal I'm getting on Laser sails.
