JES II,
Fairway width is certainly an issue.
On a very windy site, fairways must be wider.
Sites without wind can tolerate narrower fairways, thus routing and overall acreage may be affected.
As to your question about trajectory requirements at PV versus very windy sites, I'd take exception to that.
Very windy sites must consider angles to attack and ball flight in addition to trajectory.
It may be a difficult to impossible exercise to compare a tangible (PV) with an intangible (an unidentifiable phantom beachside golf course)
In order to simplify matters, let's use Seminole for comparison's sake.
To present my example, I'll offer as Exhibit A: # 17 at Seminole.
A non windy site has the following advantage.
A golfer can aim at the intended target.
On a very windy site, that may be impossible.
And, that creates additional problems.
What golfers have the courage and the conviction to aim toward the water and the confidence that their shot will be guided by the wind to the target.
Psychologically, does the golfer have what it takes to plan and execute a counterintuitive shot, a shot that's fraught with disaster should either the wind abate, or the golfer fail to execute properly ?
It's an additional element that's totally absent on a windless site.
The wind places far greater demands, on the golfers mind, imagination, shot selection and execution. That pressure doesn't exist on a windless site.
And, let me add the following.
On very windy sites, achieving balance AND a swing uniterupted by the wind, is next to impossible.
I've seen good golfers fail to execute because the wind didn't allow them to achieve proper balance, or because the wind forced swing errors.
I know that you're a fan of PV, and so am I, but, windy to very windy sites introduce additional facets to the game, facets that include pressure and difficulty, mental and physical, that don't exist on calm sites, irrespective of the difficulty of the golf course.
