Hello -After last year replacing my old Atomic 4 with a freshwater cooled Moyer Marine Atomic 4 I am ready to change the subject. Has anyone added an opening hatch to the main salon of their Pearson 30? Even with fans and a windscoop the ventilation is atrocious. Seems like adding a hatch could make the main salon a much nicer place to spend time. Please let me know and I will report back on my 'new' Atomic 4 as soon as we get in the water.Thanks! Chris
