Supply vessels captain position

If I upgrade my 100 ton NC to 200 ton NC. Would that up my chances on landing a position on off shore supply vessels I was looking at company’s in Louisiana and saw a lot of OSV were bigger than 100 ton , and yet there were a lot under 100 ton. Need help on what to do. Thank you

500 Tom /3000 Itc is what you really need to work on the osv’s in Fouchon

With 200 ton apply to Abdon Callais. Most every one else will want you to have minimum 500 ton license with the 3000 itc osv endorsement.
