The examination charge for the YM offshore practical is very reasonable for a highly qualified and experienced man usually on a weekend. Compare that with the cost of a plumber / electrician for 12 or more weekend hours.

You cant hold the RYA responsible for the cost of chartering a boat to do the exam in.

Im not sure what alternative there is. The RYA campaigns for voluntary qualification in the UK then sets up a system where those that choose to can obtain qualifications that are respected worldwide.Either take up the challenge or dont ,its not compulsory.
