I am the proud new owner of a Catalina 250. The PO had installed a regular small porta-potti. We plan to mostly day sail with a few week-ish long trips each year. Our regular lake has a handy pump out but I can't be sure about the places we will tow to such as the San Juans. I believe that I have read the Peggie you lean towards a porta-potti with the pump-out option over a full marine head and tank installation for this type of use. Is that the case and, if so, what is your recommended porta-potti with the pump-out option? Thanks. Randy
