Not realy mate, twin traps only mean you will load the boat up more and drive the bow deeper. There was a bit on Yesterday. Start of the race was averaging 15 gusting 20 and picked up to 25 gusting 30 by 3.00pm. Good decision to can the last race as the breeze was still building.
150 kg I would imagine would be a bit on the heavy side for a Mozzie....... 120, 130 would be much better.
Don't feel so bad, we had 164 kg hanging of the back of the Capricorn and dropped the nose in a few times. No cartwheel though..... but a few close calls.
