I've seen images/film of these or similar boats ploughing through seas just like that.
Try not to have her facing the wave too square-on at this stage. The trick, so I'm told, to getting over big waves is to go up the face at an angle, then to kick the rudder over to take the crest square-on & ride straight down the back of the wave. Then you kick the rudder over to go up the next wave face at an angle, repeating the process.
I was told this by a Norwegian freighter captain when I was in my mid-teens, as he was doing the above with a 30,000-tonne cargo ship in the seas at the edge of a cyclone. (He admitted that she wasn't as spritely as the corvette he had been XO of in his national service days.)
