They look ok for 2 yrs and would probably do another 2 but on the other hand - steel boat - what price for peace of mind ?

Rule of thumb is that if they have more than 1/2 of the anode left then it's probably ok - less than 1/2 replace.
Really depends when you would next plan on lifting / drying out / inspecting. If you were going to dry out mid summer for a quick scrub then don't replace them yet. No harm in buying the replacement so you can pop it on easily if required but don't put it on till needed.
On the other hand if you're planning on staying in the water for 2 seasons then i would replace them. They are a few quid and much cheaper than finding something more expensive corroding!

I assume they are wired up inside? as they look remarkably good for 2 years immersion

Could that be down to the quantity?
Pablo, we know its a metal boat, but how big and how many of those anodes did it have?

Fellow steel liveaboard here. That's a lot of zinc - what size boat is it?
You can have too much, if any paint has been blown off in a circle ~50mm with little black dot in the middle then there's too much zinc attached.
Those look fine in the image.
A silver/silver chloride half cell is an important thing to have onboard, tells you that the zincs are doing their job. This is what I have, bought years ago online in the uk.
