Re: Recommend for trailer sailer with a real head?
Hmm not sure what you consider being a 'real' head. Here are several photo's of the head on my 22 footer. I consider it to be 'real' although headroom is lacking. Not much to be done about that on any of the smaller boats.
First pic the head in to port just aft of the v-berth behind the door. With the door open it provides privacy from the cockpit. In pic 2 you'll see that it is an MSD that is plumbed for both dockside pumpout and seaside pumpout.
PS this is the smaller msd and the holding tank is only 2.6 gallons good for 3 days. I could however install a 10gallon holding tank under the cockpit behind my housebank if required.
