Big waves on a reach are no issue for me. I rather enjoy busting thru and jumping out the back. Its the big waves with wind on the nose that gets tricky quick. I never use a pusher so I walk the boat out, crew and myself. I like to get on first and get the rudders down(not locked) and one dagger slightly dropped. I also keep the main centered and loose, powering out with the jib. I like to hit the waves square on, power up, hit the wave, fall off and power back up again. I usually start cranking the main in as soon as I have solid forward momentum. I never like the way it feels to climb the wave with one hull and the other get hit by the break, straight into them and falling off on the crest works best for me.
