How often to replace anodes in Solent

[Aldous]

Hi,

I am investigating factors behind different anode dissolution rates across the Solent region, as anecdotal evidence suggests anodes decay quicker in the Hamble than elsewhere in the Solent. Some possible reasons for this is power supplies, number of boats or salinity.

I hope to determine possible reasons for this anode decay rate and the help of boat owners is important to understand the possible reasons and to determine how often you replace anodes on your boat, etc. This will hopefully lead to better knowledge and advice being provided to the boat community on anodes.

I have a survey which is designed to determine possible reasons for anode decay, how often they are replaced and brands used. If any of you are willing to fill this survey out your help would be much appreciated (see the link below), thank you. The survey is anonymous and the data will not be passed onto any other parties.

Link to survey:

Any questions or enquiries about the survey or project please email on aldous.rees@solent.ac.uk

Thank you

Aldous Rees

Which anodes, what drive system,what props ?

 

[Aldous]

It doesn't matter where the anodes are on your boat. I realise different anodes are replaced at different times.

I notice you haven't asked about the equipment on the boat and how its bonded or the maintenance schedule behind the bonding.

 

[Aldous]

I have tried to keep it as simple as possible for the person filling in and for analyses. Every boat will vary regarding anode decay and of course this will depend on the equipment present. This is however to identify general trends, so bonding not mentioned.

Might it be an idea to put the galvanic isolator question as "required"? I suspect that that would be a rather more relevant factor than type of antifoul used

I might be misunderstanding you.. you mean for your survey ?

Our boat was on the Hamble for a while, and the anode decay was much more rapid than here at Portishead. I think the speed of the current when it gushes is an element. Water here in the marina has no flow.
