There are curently several Sarum 28 on the market.
And I am interested to buy one.
I visited in Portland last year a bilge keeler outside the water and noticed some brown typical iron corosion at the keel.
Propably the keel is made of iron. The junction will then be a point of galvanic corosion.

But your statement seems more general:
Is the Sarum known as a boat with general coroded aluminium hull material?
When I read that the builder Barco has a production line of aloy working boats, I valued that as a good reference.
But your statement seems to underline a bad reputation of the Sarum 28.
Thanks,

I only mentioned the Sarum as it's an alloy design which is a few decades old, and I knew one which suffered corrosion.

Probably no better or worse than any alloy boat, as you say dissimilar metals are the key enemy, including rafting alongside steel boats and becoming an anode for them !
