Warbird,
You have illustrated the point that Hans was making.

People don't always get the full understanding.

In this case you misunderstood the meaning of wings.
Others could have a more subtle missunderstanding regarding how such a discussion could influence the F16 rules regarding wing sails.

There are many who watch the forum that do not post and therefore there would be no opportunity to correct their missunderstanding.
I have misunderstood things like this myself.

IN the context of this thread my view is that any boat 16 ft long with a solid wing is not an F16 no matter what the other specs are.
The F16 rules do not allow it.

The potential for confusion/misunderstanding begins as soon as the words F16 and Wings appear in the subject together.

These things are interesting but need to be discussed in a manner such that there can be no misunderstanding.

While we could talk about placing a wing sail on a 16ft platform, I think the concept of a modern wing sail within the rule set of the Cat 1 18sq is a much more interesting and viable concept.

BTW:-
If we were talking about the H17 type of wings.
This was allowed for when the rules were drawn up provided the craft meets the beam regulations.
