Join the club mate, ive been looking for entry level stuff for ages. You probably have some experience which goes in your favour but the amount of jobs and c.v's i've sent out is getting scary. Post office can probably tell my handwriting by now!
Besides knowing someone, the best route is likely to be via agency initially. Most T/Ocean folk I have spoken to get a 3 trip allowance to see if they are worth giving full contract to, all market dependant I think.
