I suppose it depends on what is meant by 'commercial'. Do you mean that there will now be an exam for those with YM or Coastal tickets who want to operate commercially? Currently, you just need to get the 1st aid and Medical for the RYA/MCA endorsement, don't you? I know that this is under review, but get v. lost when looking at MCA regs
It would be fantastic if you could specify a bespoke course for commercial work, but by definition the breadth of operations that a commercial user may be involved in could make this difficult. EG. Grab sampling, trawling/netting, enforcement patrols, SAR, fast tender, safety boat, fish farms etc, etc.
As a general comment, I really feel that anyone who is contemplating a course should brief the trainer as thoroughly as possible as to their workload and also do it in waters similar to their proposed operating area
. I have been on several courses in the Solent (which were nice), but generally operate in estuaries, frequently at night, where local knowledge is a premium.
Hope that this helps,
