  1. I think Soma’s point is the quality of many boat builds is sub-par. That is hard to argue with, once you step down from the GB level it can get bad. Exceptions: 1) Anything Marstrom built, I’m thinking Seacart 30 in this context, though a bit small for serious ocean work. 2) Most if not all of the Farrier line as designed and properly built to Ian’s plans. 3) Groupama 3/IDEC Sport/Lending Club, built by Multiplast, most of the toys they build have a pretty solid reputation (or we don’t hear about the problems!). 4) The Chris White Atlantic series are solid, well built
  2. Plenty of experience with XPS. It cuts easily with a sharp knife or through a bandsaw. The higher grades (40 and 60psi) are a bit easier to work with. Hotwire cutting is how the pros do it, but not necessary for an ice box. It’s good to sand the G10 with 80 grit, use 120-220grit and a soft touch on the foam or risk tearing. DO NOT spray 3m77 or rattle can paint directly on XPS, it will melt. I’d carefully brush Gelcoat when done.
  3. Probably true, from a raw performance standpoint. I suspect that L’Occitane is the easiest to make go fast consistently, followed by HB2019 and then Charal. The foil package on Charal just seems aggressive to me, an evolution of what Boris had. In one video Boris surfs to near 30kts and 15 seconds later he is down to 17kts. That is a huge apparent wind shift and not exactly maintaining a high average, and quite exhausting for a lap around the planet!
  4. Sailrocket would suggest otherwise, and 50kts on water in an open frame is a lot different than in the comfort of your 4-wheeled air-bag equipped vehicle.
  5. I don’t have one so can’t say; to your point it probably will, given my White machine CAN run it (issue is not enough upper thread tension with the stock tensioner); this machine has the same internals as the Sailrite but lacks the power of the large fly wheel and I don’t have it mounted in an industrial table, both things that would make it much more useful for doing canvas and heavier duty work. To be fair, I think V-92 thread is just find for a lot of repair work or canvas projects.
  6. V92 is about as big as most home machines run-it’s the max limit for the Sailrite LSZ1 as well. The difference is the sailrite has a fairly large under foot clearance and is a walking foot machine. I’ve been searching high and low for an industrial zig zig machine and have come up short....I would like to be able to run V-138 thread on occasion.
  7. From what I’ve seen, these are produced in aluminum tooling. It wouldn’t surprise me if the tooling has water channels to allow for precise control of the mold surface temperature during layup, cure and post cure. My estimate is the tooling is half the cost of the project, between design and machining. Sourcing high modulus carbon is probably 10-15% of the cost, maybe more during COVID. The rest is layup labor. The end result is NOT warrantied, more than likely... Other people outside Presico can and have done this (several shops in the Anacortes, WA, USA come to mind), but Presico is cer
  8. Exactly, and that data is fed into the autopilots. I’m skeptical The Ocean Race guys can push the boats harder; what they can do is trim constantly (exhausting!) and keep the average speeds up.
  9. Yep, build costs for the IMOCA60’s were reported to be well north of 6million euros...a set of foils is $500k...my take is this is 2/3rds the boat, 2/3rds the cost, not 1/6th! Whats a new Class 40 go for these days?
  10. You can get new Dimesnion Polyant Liteskin, which is somewhat like 3Di (close enough for a tramp!) and build your own.
  11. Most of the U.S Olympic N17's, the ones actually going to Tokyo, are in Long Beach. That being said, I took a look at one of their old boats and the Flying Phantom, both using PXR's. The setup I've used successfully on an Infusion had the bottom screw of the PXR attached to the mast base itself.
  12. If you go to PXR's, you have to move to 5mm line or even 5.5mm; they are 6mm max. 4mm line slips in the PXR's, at least in the last 4x I've had with max spring force set. I tend to use the stock swivel cleats and get them as low on the mast as possible.
  13. Not an issue, put some 3mm EVA non-skid on the tramp.
  14. Copy that! This was with a wall cube. The in-use battery life is fantastic!
  15. And there is no easy way to solve that with our current understanding of physics. The best bet is two well calibrated sensors as RIMike calls out. The other issue with the Triton2 system is without a central processor (the H5000) there is no way to store calibrated data on the bus, unless you have a more advanced speed sensor that can be calibrated independently with a direct interface so only calibrated data is pushed to the bus.
