Very correct, but the range available can be limited in some countries where there are very few good reliable chandleries. That's the only reason I'm looking at this thread is to see where I can find an equivalent to the West marine stainless range of connectors. Alas a lot of the stuff for sale is either poor quality recycled stainless (It does corrode due to impurities, casting faults and lack of annealing), or chrome coated brass fittings that look good until scratched.
The only type of plug and sockets for a salty area that really does impress a surveyor, are some type of hard plastic based ones , (ABS or Delrin), with gold plated phosphor bronze or similar contacts. Alas a tad too expensive for my old lifeboat conversion.

Best place for choc block connectors is in the skip.

I tend to use blue sea terminal strips.
or if it’s something you regularly need to change then maybe wago connectors available in different sizes - assorted box from screwfix attached!

Hi
Whatever type of connecttor block I use ( on cars, RC model boats or full size boats, I always load up the connection with silicone grease. We have never had a rust problem.
Good luck

Good stainless steel ones look exactly the same as the El-cheapo steel ones when new, and it's those parts that cause no end of electrical failures on boats or in damp garden sheds.

I put tinned copper bootlace ferules on bare end wire then crimp with one of these tools:

I end up with a square cross-sectioned crimp which I can heat shrink as required. Bootlace ferules come in many sizes to suit the wire cross-sections and with or without a protective boot attached. The great benefit is a quick secure pin connector can be completed by a rank amateur.
As an earthing terminal strip I have glue mounted 5 -way Wago 221 connectors on a backing strip linked in series by jumpers. Allows connections for a range of wire sizes [24-12 AWG]

If the chocolate blocks are corroding so are the cables tinned or not, you either need to put the connections in a waterproof box with proper IP66 stuffing glands and ideally a vapour proof breather or solder/crimp with adessive lined heat shrink over the top.
If you are using a box then why not use proper din rail mounted connections, there is nothing like seeing chocolate block connections to shout DIY. if I see them on a job then I immediately consider a re-wire!
Wago's are great, maintenance free and vibration proof as there are no screws. This type of spring/clamp is also available in din rail mounted connections and frequently used on machines where vibration might be a problem, electric hoists for example.
