Andrew,
Capt'nKarl makes a valid point and his post was appropriate to the Forum.
I understand you have a vested interest to defend the design deficiencies of your product, but you must remember, we are the people that keep you employed and your company in business. Rather than criticizing a valid complaint, you, as a company representative, should instead acknowledge the issue and state what the company is doing to rectify this well-known problem.
As Capt'nKarl rightly points out, the simple fact that one must use a rain repellant to have acceptable visibility in rain or heavy seas shows the inadequacy of the wipers.
So that I am not accused of making an inappropriate post, I suggest a fix.
Move the wiper motors to the center of the windscreens and use longer wiper blades with a longer wiper arm. So easy, right?
As it stands, my R29 OB windscreen is about 8 sq ft per side. The wiper on each side clears approximately 1.5 or perhaps 2 sq feet. 20 to 25% of the total area. As Capt'nKarl also noted, no one would be happy with this performance in an automobile. Given that driving on the roads is much easier, given the cues of road reflectors, road stripes, generally better visibility due to more lighting than on the water, I would think you would understand the concern we owners have instead of minimizing and unduly criticising it.
With regards,
