Re: installing holding tank in Seafarer 30
Did you ever get the information you desired? My 30 Swift Sure had a bastardized setup where he installed the hold tank on top of the shelf in the head. Just sits there with all the plumbing... the guy was supposed to be an engineer who owned it before me, but his degree of fit and finish was abhorable. I will be redesigning it and will be looking for a better method.
