Hey all...

Lonny's Old Seaport on the Tamar has an issue with silt, especially after this latest drought. Its currently being dredged mind you.

At low tide the inner berths leave the boats on /in the silt. Outer berths have an amount of water available but I'm not sure how deep.
Other than the fact she throws of an odour at times, I'm wondering about other implications.

Firstly, Would sitting in the silt - its very soft from what I can tell (on dude apparently fell in it backwards on the piss and suffocated), would that be very degrading to antifoul or could the mechanical debridement work to ensure "pathogens" cant get a good hold?

Thoughts?

where boats sit in the mud always seems to be a home for barnacles probably less of an issue in tassie with low water temp once there out of the mud and in a clear berth the growth seems to catch on easier to the ares that have mud in the paint

one advantage of having minimum clearance....if you are away from the boat for extended periods and have a calamity such as a seacock give way, or extreme rain it won't sink all the way down. Just settle a bit deeper - hopefully water level below the engine.

is that an issue only that far up the Tamar Ben, or would it be the same down at Gravely/Beauty Point?

The silt is worse in that area due to floculation. Silt particles held in suspension in fresh water, meet salt water and become charged, the particles then stick together and settle.
Rosevears is a bit silty and Gravelly Beach a lot better. Not really an issue further down the river.
Pretty toxic silt too. Pitty they can't sell it.

You can say that again! I will have to be more carefull what I say in jest.........

After i purchase a second hand Bukh DV 24 for my little boat before cleaning the internal cooling system it had been coated in what I believe was silt .
Id say the boat it came out of at some stage was mooring in a river or the head outlet was to close to the engine inlet
Was thinking of using Duck but went with my tradition means to clean the cooling system
So if it breaks down in a few years time I guess you will know what Ill call the engine
