[Public-List] Integral Water Tank in Pre-liner Alberg 30

[Jonathan Bresler via Public-List]

Folks,

Thinking about doing a bit of cruising, that will require carrying fresh
water.  Constance, a pre-liner Alberg 30, appears to have an integral water
tank under the v-berth.  So far, the only access to the tank is through the
two storage areas under the starboard and port v-berth "flats".  The only
connections appear to be top mounted deck fill line, vent line, and a pick
up tube that provides water to the galley and the head.  The connections
are mounted onto a 4"? diameter plate that is secured to the tank with 6?
screws needing a straight blade screwdriver and an uninterrupted bead of
silicone over the screw heads.   The top of the tank is covered in the same
drab yellow paint that is in the forepeak.  Under the paint appears to be a
coating of some sort, as the painted surface is not a flat as one would
expect a tank to be.

Yesterday, after freeing the deck fill (thank you PB Blaster Penetrant), I
filled and emptied the tank four times.  Previously the tank had some
quantity of propylene glycol (the pink stuff).  Read the maintenance manual
and the web page on water tanks on the website (alberg30.org); these appear
to speak to liner boats only.

Is there a drain?  Would it be under the bit of floor in the "V" of the
v-berth?
Is there an access port that I am not seeing?  Perhaps under the seat in
the v-berth.
Anyone opened up their fifty year old tanks and looked inside ?

Jonathan
