Yes.
It could be that TC would do from bow to stem, and this would meet the regulations, either the small vessel regulations or the large vessel regulations. If the fisherman decides to add on an extension, that extension would be covered by the TC regulations, but it would not be covered by the DFO regulations. DFO would say that it's bow to stem, and they don't include the extension. You can have have a 22-metre boat plus a four-metre extension. You would meet the regulations for DFO because the maximum length is 22 metres, but you add on this extension, which is not covered by DFO. Therefore, you're able to fish with that boat even though it's larger and may not have the appropriate stability assessment done, or it may be a risk factor because you put more traps on to it and so forth.
