TL;DR - drc13 nailed it.

In more detail: it is not just about the foil, it is about the whole system. You are on one of the best systems (Code) for big guys because it is very stiff. At 210lb geared up, I can't recommend the previous gen Fone gear due to the lack of stiffness. Not an issue for lighter riders, so ignore the mates. Can't comment on the new gen Fone stuff.

With respect to the foils you asked about, the 7seas is an older gen foil with a lower aspect ratio and thicker foil sections than the Code S. In my experience, if you are starting from complete never-foiled-before scratch, these older, thicker and lower aspect foils like the 7seas are more forgiving. This benefit lasts maybe about 10 sessions max, and then all the advantages of the Code S foil take over and it will almost certainly be the better foil to progress on. Considering the system stiffness differences, the crossover is probably at more like 7 or 8 sessions tops. So, like drc13 said, you have great gear so just stick with it.

If you cannot foil at all at present, try to split the learning task. Handle the wing on land. If you can, borrow or buy a cheap used offroad skateboard. For foiling, spend a few hours towing behind a boat. It may seem expensive if you have to rent, but learning to fly the foil without having to deal with the wing shortens the learning curve tremendously and helps you dial in your mast placement.

Don't worry about a bigger foil than the 1540 right now. Skill will bring your low end down from where it is now more than any gear. For gear,a narrower board will likely make a bigger difference to your low end than any foil or wing. You board dims sound great for a 1st board, but a more advanced board will unlock a a bigger performance envelope once you are ready to deal with the drawbacks.

FranP, other than rider skill being a relevant factor in vmg, I don't agree with anything you are saying.

The density of the fluid is only one parameter in the drag equation and does not automatically mean drag in the higher desnity medium is higher. John Shuttleworth showed, back in the 90s, the air drag for a very sleek catamaran sailing upwind was substantially higher than the water drag. A foiling vehicle, such as our boards, will relatively reduce the water drag substantially compared to the best displacement hull possible.

Your own 7.3% calculation completely ignores your assertion that both speed and angle matter, accounting only for angle.

You've completely ignored the input here from people who have actually ridden both the the PR sail higher and faster, contradicting them to make an apparently theoretically based assertion that the PR must sail slower because it is sailing higher.

The AI barf of a calculation is of very limited value, these tools are not remotely reliable for such kinds of calculations at this point. Correctly including the speed component of vmg in the calculation and you can easily end up with a 15 or 20% improvement in vmg. Or a whole extra lap for a typical 2km upwind/downwind run during a 2.5hr session. Hardly insignificant.
