Lamination materials are typically sold by the pound. An H16 hull weighs more than an F16 hull, but there is a huge difference in the labor that goes into one. Controlled resin contents and more importantly the finish work that goes into a modern hull to finish seams, keels etc. Nobody wants a performance boat with H16 style hull joints.
Are you kidding me? You may try to sell it by the pound but nobody buys it by the pound. Bagging and infusion takes less labor then hand lay-up of the olden days, the labor is at Asian rates, the finish is the result of the mold or tooling. OK High tech parts may cost more I still don't see 50% but I'm getting dizzy from the spin.
Here’s the spin.
I build composites for a living so I know a bit about this. I do not build boats anymore so there is no interest here on my part other than as an observer.
Polyester resin, gel coat, chop strand mat and rovings are all purchased by the pound. These are the things that make up your H16 of the day. I have visited a factory making F16. They were using Vinylester resin and gel coat still purchased by the pound. The fabrics are textile weaves, knit cloth and uni directional fabrics. The knits are still by the pound, but the uni and textiles are by the square yard. (Note Chop strand mat and woven roving run between 1.05 1nd 1.50 a pound, knits anywhere up to about 2.50/lb depending on the fabric weight, where a 6oz textile weave is about 3/sy or almost $9 per pound should you care to compare)
With an H16 assuming your mold is good you glue together the hull and deck, trim the edge and you are done. The newer performance hulls all have finished seams, requiring labor to fair and finish whether it if it is gel coat or paint it is still a lot of work. I have followed your blog – so you should know a little bit about the amount of work that goes into a fair shinny surface. Apart from the regulations on most developed countries this is a big part of the reason many of the companies have gone to China.
Open up your Harken or Ronstan catalog and look up the difference in price between the carbo line and the Hexaratchet stuff, look up Dyneema lines vs. pure polyester, look at sat-masters vs. holed chain plates. Everyone more the double at current prices. Add to that the fact the cost of the cheap stuff has still had its fair share of increase as well.
