I agree that I'd like to see less spray.
Perhaps flares on both sides of both hulls are in order, even though
they would add to the cost. Elan trimarans tend to be a lot dryer than
Corsairs, and part of this reason is the way they handle the hull
flare. I don't always agree with Robert, but he does make some good
points, and flares would be one of them.
That said, I think it's misleading to judge the amount of spray
relative to the sea state. It's a sailboat moving at 14-16 knots, so
the real gauge is the amount of spray kicked up by other boats at that
speed.

I too had noticed those spray drops coming from the bimini and don't like them at all! I'm with JT and also believe it is spray coming from the ww bow, it would be interesting to know whether this "dripping bimini water" comes from the ww or lw side of the ww bow, pity there is no shot of the ww hull in this video showing the bow's movement.
This is to be a cruising boat, or better put a fast cruising boat, and this amount of wetness in the cockpit in these rather pleasant sea conditions is very annoying, to say the least - imagine having to wear your oilskins in this kind of weather.
I think the ww bows need more thoughts put into them leading to some kind of spray deflection, be it through being longer and/or different shape, a deflector or some other kind of cockpit protection.

The only dry spot, helm and entrance to the salon. That's why they are standing there to take to gps fix. THose foam sponges aren't there for looks. Even the Cofts video you can see some water coming off the WW bow.

I think I will deal with it as normal for any boat design. Move fast enough or in high enough windspeeds and add dodger panels for the cockpit or get wet. THis craft is no different.
