This has the look of a professional factory installation
. Seacocks are bronze
, which are virtually indestructible and stainless ball valves all indicate a lifetime installation
Many proven hull
designs incorporate keel
tankage as a feature of utilizing space and balance. The simple filter likely indicates a water
tank sediment filter; again, a common design.
To verify, look up the blueprints for this vessel. Tankage will be indicated in the keel
. If this is not a factory design, the posts regarding integrity destruction would apply. An array of aftermarket holes through the strongest part of the boat
would both be a danger
to a bolted lead keel, as well as a danger
to the hull
'on the hard', as load would be unevenly distributed.
Additional to keel tankage, such hull designs indicate quite specific keel lift
points. If you lift
the keel on a tank vs. keel structural members, you risk rupturing the tank. Again, internal tanks
stopcocks are designed to stop such flooding events
, should the tank be breeched by running aground, hitting submerged objects, etc.
