Converting from a Yacht CoC to a Small Vessel CoC

Many Yacht engineers ask us if they should convert their current Yacht CoC to an SV CoC.

For those who already hold a CoC, there are conversions listed in MIN 524. Starting with Conversion A1 (converting Y4 to 2nd Eng SV) going all the way through to Conversion R (converting a Merchant Navy 2ndEngineer Unlimited to Chief Engineer SV <3000GT & <9000kW) and covering Tugs, Fishing and Merchant Navy on the way.

The Yacht CoC conversions are:

A1 – Y4 to Second Engineer SV <3000GT & <9000kW CoC

A2 – Y4 to Chief Engineer SV <500GT & <3000kW CoC

A3 – Y4 to Chief Engineer SV <3000GT & <9000kW CoC (this conversion should be approached with caution, as it is essentially converting a Y4 straight to a Y1)

B – Y3 to Chief Engineer SV <500GT & <3000kW CoC

C – Y3 to Chief Engineer SV <3000GT & <9000kW CoC (this too is a big leap in knowledge and experience required)

D – Y2 to Chief Engineer SV <3000GT & <9000kW CoC

E – Y1 to Chief Engineer SV <3000GT & <9000kW CoC

Some of these conversions are a straight swap, but many require courses and oral exams, but it’s all plainly laid out in MIN 524. The main point you need to know is that the written modules and exams are different from the Yacht ones, even though they all have the same names. So if you were going to convert your Y3 to an SV Chief CoC, you would need to do the SV version of the Applied Marine Engineering course, and so on.

The only course that is the same across the board is the General Science I & II, as this is the Merchant Navy one that all sectors are required to do.

There was a time when Y3 CoC holders wanted to convert to the SV Chief CoCs, but none of the training providers had received MCA accreditation to run the SV courses. The MCA agreed to accept Y2 Applied Marine Engineering in lieu of the SV course for a short time but this is no longer the case, as the courses are now readily available.

For those trying to decide whether to convert their Yacht CoC to an SV CoC – you do not have to convert to the SV CoC unless you need it to work on a workboat/fishing vessel etc. If you work on yachts then you can continue along the Y route until these CoCs are phased out in 2021. Even when the MCA cease issuing Y CoCs you will still be able to get yours endorsed every 5 years, and it will still be a recognised CoC. You can convert at any time, there is no need to rush into a conversion unless you see yourself leaving yachting.

There is also a possibility that due to differences in actual sea time requirements, Yacht to SV CoC conversions may be restricted to yachts only, therefore we would recommend that you stick with the Yacht CoC route until the revision to MIN 524 is published.

Note that the 1.5 days rule for calculating Yacht sea service cannot be used for Yacht to SV conversions.

The different ways to convert your Yacht CoC to an SV CoC are laid out in detail in MIN 524, but we have listed the basics for you here:

IF YOU HOLD A Y4 COC;

Conversion A1 – converting Y4 to 2nd Engineer SV <3000GT & <9000kW

whilst holding a Y4 CoC, complete 6 months SEA service on yachts of at least 350kW or take the 2nd Engineer SV oral exam.

Conversion A2 – converting Y4 to Chief Engineer SV <500GT & <3000kW

whilst holding a Y4 CoC, complete 6 months SEA service on yachts of at least 350kW.

successfully complete the SV Statutory & Operational Requirements module

complete the Human Element Leadership & Management (Management Level) course

pass the oral exam for Chief Engineer SV <500GT & <3000kW.

NOTE: This conversion is equivalent to upgrading Y4 to Y2 – there is a requirement for deeper knowledge of refrigeration, electrical & other subjects that would normally have been covered in either Y2 Advanced Hotel Services or SV Auxiliary Equipment II.

Conversion A3 – converting Y4 to Chief Engineer SV <3000GT & <9000kW

whilst holding a Y4 CoC, complete 6 months SEA service on yachts of at least 350kW, including a minimum of 3 months service on yachts of 750kW or more

successfully complete the SV Statutory & Operational RequirementsSV Applied Marine Engineering & General Science I & II modules

complete the Human Element Leadership & Management (Management Level) course

pass the oral exam for Chief Engineer SV <3000GT & <9000kW.

NOTE: This conversion is equivalent to upgrading Y4 to Y1, therefore we strongly advise that you only continue along this route if you feel you have adequate experience – there is a requirement for deeper knowledge of refrigeration, electrical & other subjects that would normally have been covered in either Y2 Advanced Hotel Services or SV Auxiliary Equipment II.

IF YOU HOLD A Y3 COC;

Conversion B – converting Y3 to Chief Engineer SV <500GT & <3000kW

this is a direct conversion, with no service requirements, however you must complete the Human Element Leadership & Management (Management Level) course

Conversion C – converting Y3 to Chief Engineer SV <3000GT & <9000kW

whilst holding a Y4 CoC, complete 6 months SEA service, or whilst holding a Y3 CoC, complete 3 months SEAservice.

successfully complete the SV Applied Marine Engineering & General Science I & II modules

complete the Human Element Leadership & Management (Management Level) course

pass the oral exam for Chief Engineer SV <3000GT & <9000kW.

NOTE: This conversion is equivalent to upgrading Y3 to Y1 – there is a requirement for deeper knowledge of refrigeration, electrical & other subjects that would normally have been covered in either Y2 Advanced Hotel Services or SV Auxiliary Equipment II.

IF YOU HOLD A Y2 COC;

Conversion D – converting Y2 to Chief Engineer SV <3000GT & <9000kW

whilst holding a Y2 CoC, complete 3 months SEA service on yachts of at least 750kW

complete the Human Element Leadership & Management (Management Level) course (if you gained your Y2 CoC before HELM M was a requirement)

pass the oral exam for Chief Engineer SV <3000GT & <9000kW.

IF YOU HOLD A Y1 COC;

Conversion E – converting Y1 to Chief Engineer SV <3000GT & <9000kW

this is a direct conversion, with no courses or service requirements, however you must complete the Human Element Leadership & Management (Management Level) course if you gained your Y1 CoC before HELM M was a requirement.
