Hoping for some advice on our latest project
- We're in the middle of replacing the bilge
mounted water tanks
on our 1986 Bristol Channel Cutter
The original water tanks
were stainless steel
and included standoffs welded on the bottom of the tanks. Obviously that makes sense to ensure the stainless isn't sitting directly on the bottom of the bilge
and has some airflow to ensure the stainless remains...well, stainless.
We're replacing the tanks with rotomolded PE tanks (the same ones used by the OEM in later BCC builds). We were working on some supports underneath the tanks to ensure bilge water could freely flow. But, while conducting a dry fit, we noticed that both tanks there is room between the outboard
bottom of the tanks and the bilge for water to flow, and since the tanks are plastic, there doesn't seem to be any need for an air gap like with stainless. Lastly, it seems like having the entire bottom of the tank on the bilge would provide the best support given the weight of water.
So...I'm scratching my head
a bit and wondering if we should glass in standoffs on the hull
or just rest the tanks directly on the bottom of the bilge.
We'd always heard that tanks need standoffs from the bilge so we feel like we must be missing something and look forward to your thoughts.
