MARS III and IV are demanding courses but you must be willing to listen, work hard and be a team player to get through it. Here are a couple of tips that may assist you getting through these courses:
Spatial awareness - I have found that many students have no clue how to marry up what they see on a chart to what they see from the bridge. If you can, get charts of the West Coast Gulf Islands speccifically 3440, 3424, 3441, 3442, 3443, 3478, 3477, 3479. There are a few others but go here to get a general look at the area
http://www.charts.gc.ca/charts-cartes/paper-papier/pdf/pacific-index.pdf. Go over these charts and see where the ferry routes are, calling in points, points of land, traffic lanes, names of islands, passages and coastal towns. This knowledge will give you a leg up when you are navigating or as Officer of the Watch (OOW).
Teamwork on the Bridge: If you are the navigator or OOW you are a TEAM. You help each other to have a successful watch or passage; the OOW assisting the Navigator in identifying lead marks, points of land etc and the navigator pointing out areas of safe water in case of a Man overboard (MOB).
Ability to deviate from the plan: Officer in Charge (OIC) of the ORCA's love to go see things that interest them. Eventhough you will spend hrs doing your passage planning all is not lost if for some reason you have to go away from your planned route. Realize that it is a big body of water out there and if the OIC orders the ship onto a wild goose chase, remember where you planned destination is and give the OIC a recommendation of of course to steer and time to regain track.
Radian Rule: 1 degree off your lead mark at 1 mile is 33 yds off track - thus 1 degree at 3 miles is 100yds off track (port or starboard). Remember these simple numbers and you'll be a rock star.
Terminology - Nothing ticks off your Course Training Officers (CTO) and OICs more than calling a chart a map, down below - downstairs, a ladder a stair, a deck a floor, a bulkhead a wall. Fore, aft, port, Stbd know these terms and use them. You have chosen to become a professional Naval Officer therefore you must learn the language or you will look like a fool in front of more senior Officers and NCMs. Worse you will not gain any credibility with them.
Finally when on the Bridge and you faced with a situation; MAKE A DECISION! It may be the wrong decision and the OIC or CTO will correct you but there is nothing more pathetic then an Acting Subbie grippping the pelorous with their mouth wide open and a vacant look in their eyes unable to decide to alter course 15 degrees to stbd to avoid a vessel crossing ahead of you.
Hope this helps and good luck at Venture!
