So I recently became the owner of a 1975 Tartan 27 in pretty decent shape. The boat
did fine on the test sail and passed the electrical
portion of the survey
with flying colors. The test sail was two weeks ago and the boat
was last run ten days ago, and has been plugged into shore power
since then. Ten days ago the engine
was serviced just before it last sailed.
Today I came to see the boat for the first time as the owner and found a substantial amount of water
in the bilge
(well more than normal) and also discovered that the manual pump
does not appear to be functioning. After some exercise involving a portable bailing pump
and a bucket, the bilge
is now at a much more reasonable level.
The house battery
has a whopping charge of millivolts, and the starter battery
has a charge of 2.6 volts, so the reason the bilge hasn't been pumped is clearly electrical
. Everything was turned off when I arrived..... What could possibly cause two working batteries
to die in 10 days? Also, I'm pretty sure I know the answer to this question, but at that level of discharge, they need to be replaced for sure, right?
