In Europe I don't see the market for a successful 20. Or a F20.

An F18 is doing almost all you need from a big cat. They can go around cans. They can do raids. They do not cost an arm and a leg. A lot of people are sailing one. You don't need a tilt trailer. That's a lot of tickboxes that the F18 checks.

What's missing to the F18 that would warrant a 20 design:

* Maybe, a 20 is better off-shore in deep waves. How much better? Not that much, is it worth the price of yet another class? probably not.

* Who's the target? A 20 is a good refuge for heavy crews, but those big crew are not that common. And there is an easy solution: split the crew, get two F18 and give the tiller to a lightweight...

* A 20 is faster. Granted. But we already have a fast established quick 20 class: the Tornado. It's in decline right now, because without the attraction of the Olympics it is still a big boat hard to trailer around...

So what market is left for a 20? A handful of crews too heavy to be competitive on a 18 and refusing to split. A handful of rich guys building big light overpowered cats to be the first over the line in raids. That's it. In short, not enough to sustain the development costs.
