I have decided to do some work to revitalise some of the windows. I am replacing the window rubber seals and cleaning up the metal frame. The crazed acrylic window is being replaced. This is the porthole/portlight between the cockpit and the main saloon.
Sadly the crane company has had to cancel the launch because the crane is being held for a week in Doncaster.
Likely new date in September.
Still we have another month to get the boat even more seaworthy.
Hey ho me hearties.
Anne Marie did not have any anodes fitted so I have added a small one because her circumstances have changed.
Sea water acts as an electrolyte and causes electrolysis to occur between different types of metal and if you are not careful your expensive propellers and propeller shafts or skin fittings dissolve over a couple of years into nothing. An anode is made of a metal which is worn away in preference to expensive metals. This one is made of zinc.
From an electrolysis point of view Metals are listed in accordance with their Nobility. Zinc is a less noble metal than everything else we have on the boat underneath the water and therefore will erode quicker. It is sacrificed for the good of the more noble metals. – much like life really.
The anode has to be bonded using wires to the metals it is supposed to be protecting. So I have to wire it to the propeller shaft and rudder. Not sure how yet but I have time.
Although I will be painting everything that is metal under water Anne Marie will be moored alongside other yachts some of which will be connected to shore power (240volts).
The link to shore power means that there will be small electric currents flowing underwater which will create the electrolytic reaction.
In the past I suspect that Anne-Marie was moored away from other boats and therefore the likelihood of having regular or consistent electric currents generated was low. This will not be the case in the future.
So we are going to watch over the next year how this anode acts. Will it corrode quickly or will it not? We shall see.
I have replaced all the skin fittings. A number have been sealed permanently with fibreglass and epoxy and others have been created.
These are Blakes bronze seacocks which can be shut off:
2 no. Toilet (heads) inlet and outlet
1 no. Kitchen (galley) sink drain
1 no. Shower and heads basin drainage sump outlet
1 no. Bilge pump
1 no engine cooling inlet.
Lastly the ship’s log sensor fits in a plastic through-hull.
Each fitting has a plywood backing pad bonded and sealed to the inside of the hull. Four bolts secure the fitting with lots of sealant.
No I am not being rude. The Stuffy Box is a simple seal that goes on the propeller shaft to allow water lubrication but stops leaks – or so they say.
Anne Marie had one already installed but as it was quite old I bought a replacement. This one is by Orbitrade.
Greasing the shaft proved a messy job.
The new propeller arrived today supplied by T Norris Marine https://www.tnorrismarine.co.uk
Just got our new cushions for Anne Marie from Martin’s upholstery supplies in Mereworth, Kent. Ordered Monday and delivered at 6am this morning.
Now to buy material and get the covers made.
