I refer to this as "bow busting". When racing being as lite as possible means emptying your tanks, but in the case where we sailed my buddy's dad '80 Catalina 30 outside from Mobile, Alabama to Pensacola, Florida one spring day I was grateful I had ballast forward. I had to sail in the troughs and our bow was cutting into 8 foot waves going forward close hauled that day. It was my first experince with the 30 Catalina in seas like this and she sailed well, but I thought the boat was going to crack in two hearing that deep and loud resonnance from the bow slamming forward. Thats when I called it, "bow busting"! Having a full v-berth water tank, I felt was more of a positive then negative. Fiberglass, you gotta love it.
