I can't get that website to load, but it seems to be a discussion of rams compared to tubes, so I have a few counterpoints:
I know from getting rams ready to fly that you better should fill the foil before launching with some air, this takes time as well.
Yes, it does take time. My ARCs are fully preinflated by the time
I've unwound my lines & got "dressed" (harness, gloves, booties, etc.). The only tube I rode took about 5 seconds of line tension to preinflate before launching.
You can leave the lines at the tube kites as well. But when you take it of, it will be faster and without tangling of several hundred small lines, which can happen at foils.
I never removed the lines from the foil, & the bridles never tangled. If I did want to remove the lines I'd attach the right & left pigtails to each other, just like on a 2-line tube (to prevent tangling). Of course it's a non-issue with an ARC.
the por guys who have to launch straight from the powerzone. For me this is the biggest safety threat when it comes to foils.
Yes, you can use it from the edge of the window as well, but I never see anyone doing it.
You'll likely see it soon, with modern ARCs (2002 & newer) with zipper vents. With any foil it's easier (& safer) to fly it low to the water edge of the window, instead of the top edge.
And if you have a small beach and you have special wind conditions, someone can easily go with a tube kite into the water
and start it from the edge there. With a foil it is not necessarily working. Maybe with the new Tital it should be ok, since the water can run out of the foil at the tips easily.
I think ARCs can be drift-launched with sufficient preinflation, which may require using a pump
Bridled foils should be similar.
indeed, foils are good to be relaunched, if not full with water (once again,the Titan doesn't have that problem anymore)
I think you'd be safe saying that about any modern foil. I've had my ARC on the water for about 20 minutes (pre-released safety, & subsequent tangle without stopperball) & still relaunched fine. I also swam it in once for about half an hour when the wind died completely (so I didn't bother rolling it up) & it only took on about 2 cups of water (& lost very little air - I've relaunched it with less, & when BOTH sides were wet with much more than 2 cups).
In waves the foils can be easily washed and a relauch isn't possible.
To relaunch a tube after waves hit it, is way more possible.
That's strange. My experience is the exact opposite. It's so gusty & shifty where I launch, that I've crashed in the surf more times than I care to remember, & ARCs will usually float like an air mattress & relaunch, but tubes will usually get tumbled & not relaunch until after retrieving the kite (usually requiring winding in the lines), sanding, unwinding....
The relaunch throught the powerzone can be dangerous as well, instead of relaunching it at the window.
I don't know about you, but when I'm doing a water-relaunch, there's usually
at least a linelength of open water downwind.
I only saw once a foil rider jumping almost as high as me.
When I switched to ARCs my jump height stayed the same (well, maybe a BIT higher with the ARC).
I didn't see a foil jumping longer than me.
When I switched to ARCs my jumps DEFINITELY got longer.
I'm not sure about it.
I found no difference when I switched. Same for the bridled foil.[/u]
