Good posts. ISO will only be available for late model/year boats. It's been a long time since I researched that prior to doing my stability test. Thinking it is like 2005 and newer? Stability test is requirement for C license.
Good advice also on insurance. No one wants to breach their policy. Consequences are devastating.
Just a follow up to the above comment about "stability being a requirement of a C licence". A C licence or C# basically serves to document the vessel for Transport Canada as being in commercial (non-pleasure craft) service (and can aid search and rescue via a searchable database). C# are issued and handled via Ottawa and is not really realted to the stability requirement. Stability is but one safety requirement under the Small Vessel Regs. ISO 12217-1 stability, like another member said, is required for any guide boat (non-pleasure craft use) over 19'6" built/imported after April 1, 2005...or any vessel modified since April 1, 2005.
To put it all in context: the SVCP "Blue Decal" program is handled by your regional TC inspector and summarizes all the regulations or steps for you to be compliant. Besides stability; registration with a C#, proper certifications, safety equip, lights, bilge pumps, alarms, etc. are other requirements.
As said by others before in regards to going beyond 25NM, NCII... for certification, SVOP is an NCII certificate. Others have suggested a Master Limited (60Ton) as being an alternative. The 60Ton certificate is a limited certificate as set by the inspector you do your oral exam with (which is exam # 3 in the process, Chartwork/Pilotage and Nav Safety/ColRegs are the other 2). On a 60 Ton certificate they limit master to a specific vessel and voyage route or area. Which is why some members are saying you may be able to obtain one for going beyond NCII voyage. However, that is contingent on the examiner/inspector with TC allowing it for your situation, experience level, vessel construction, or whatever they go by when stamping a voyage restriction/allowance on the final certificate. I would check with your local examination office first before embarking down the 60 Ton route and be up front of why you are thinking of going that route. 60 Ton examinations are now done either done via TC in Victoria (for Vancouver Island) or via TC in Vancouver.
Also to note, MED A3 does not transfer to your ML60Ton requirements. Before getting a 60Ton, you must upgrade to MED A2, a 4 day course covering practical immersion suit, life raft and firefighting, as well as passenger control. The other pre-reqs for 60 Ton (to be valid for passenger carrying vessels) are 60 days (1 day=8 hours) commercial seatime, Transport Canada medical with one of their listed doctors, ROC-M with DSC or ROC-MC, and Marine Basic First Aid, plus the 3 exams with TC. You also can't be colour blind, as that shows up during the medical.
For those on the North Island, North Island College frequently offers all those courses as well as the 60Ton prep. course. I went through the process a few years ago and am currently tutoring a couple of guys towards their Nav Safety, 061 exam which is basically memorizing the entire ColRegs start to finish, and other nav. safety practices.
Anyway, for anyone with related questions, feel free to PM me anytime. I've helped out several members on here with their boats. I do stab tests (including ISO), take care of all the registration paperwork for C# application and assist with SVCP Blue Decal paperwork as well. Most of all, I just like to help people get the right answers to their questions. Which is why I love the spirit of this forum. Cheers.
