I'm rebuilding an O'day 39. I've removed the entire holding tank
system and will be starting from scratch. I'm thinking of installing two Raritan Marine
with fresh water
. The boat was originally fitted with a 15 gallon holding tank
under the forward V-birth handling the port side forward head
and a 20 gallon holding tank under the starboard settee to handle the starboard head
located just forward of the quarter birth. My question: Would it be better to place a larger holding tank under the port settee instead of under the v birth since it would be a much shorter run and it could likely be positioned as to not hold waste in the line?
The only advantage I see with the factory arrangement is that both tanks
can be serviced at the pump-out station with the boat on a starboard tie. I've never pumped out a boat so I have no idea if this is a big deal.
I have Peggie Hall's book and she likes the holding tank under the V-birth because it provides a great location for a vent. But I don't think she'd like that location for my boat since it requires a long up hill run for the waist hose connecting the head to the holding tank. I have included a layout of the boat. I look forward to any and all comments.
