I am battling a strange problem on board which is nowcausing me concern and I am wondering if anyone has ever experienced a similar case.
On entering the boat I smell quite a strong sulfur smell. It is the same smell that would come from a head
that has not been used in a while however the smell is not coming from the heads. I have alsonoticed that nearly every power lead (plugged in or not) and some other soft plastics/rubbers have changed color to brown. I have also noticed that certain coins I have on board and other copper pipes are being tarnished and turning silver.
I had quite an amount of sea water
come in to the bilges when an a/c pump was changed and am thinking that there may stillbe some trapped somewhere. The boat was also closed with no ventilation for a few weeks and would have become quite hot inside.
The strange thing is that the discoloration has occured to plastics (mainly power leads) regardless of where they are. The inflatable dinghy
which is stowed in the bow now has 2 brown handles. The shore power
lead is brown (only the part that is inside the boat). USB cables
for pc now brown.
I am concerned that there is a very corrosive gas or substance on board.
Any shared similar experience would be really appreciated.
