Water Tanks (originals and add-on's)
Pat Bell, Previous owner #41, Kialoa
I was the Editor of the NTA Improvement Bulletins for some years and have a copy the original Pearson Co. construction manual for the Triton which gives specs for the original water tank as having a design capacity of 27.5 gallons.
Vent line 60" copper tubing, 1 – 1/4" IPT fitting.
Suction line, 16" - 1" OD fiberglass pipe with 1/2"OD x 4" end piece attached.
I owned #41, " Kialoa" for some years of sailing her between Block Island off the Rhode Island Coast and Halifax, Nova Scotia. We never had any structural failures. I only gave her up due to back problems after 12 years of retirement to our retirement home at Wonsqueak Harbor, ME. Glad to help any time.
