To measure a one-inch change in waterline submersion at the transom would require approximately 2000 pounds placed AT THE TRANSOM. Removing 200 gallons of water from a location about 14' forward will result in an immeasurable trim change.

All this info is from a former owner of a Pacific Trawler (me) who attempted to correct a bow-down trim state caused by the three foot transom extension added by Pacific Trawler to create the 40' version. I found the boat needs about 2000 lbs. of lead in the lazarette to trim properly, even with all water and fuel tanks full.

In my experience with my Pacific Trawler 40, those 200 gallons of house water was more than sufficient for my needs, even on extended trips throughout the PNW. I soon learned to re-water after a week or so underway, and never ran out. And never missed a water tank gauge. Your mileage may differ, of course, but one of the many virtues of the Pacific Trawler 40 is it's ample tankage.

Thank you! Great to know.
