Questions on Buoys and buoyage

  1. Approaching from seaward, how do you identify the entrance to a marina in Israel? A flashing green light on the right and a flashing red light on the left.
  2. At the entrance to a marina in Israel two lights, green and red, are flashing. What do they mean? Entering the marina, the green light is on the vessel's starboard side and the red on her port side.
  3. A sailing vessel heading north-west, with the wind from the north-east, sees flashing red and green lights (side by side) on her starboard side. What action is required? This is a marina entrance: keep a sharper lookout, stay alert, and keep your course and speed.
  4. Which statement about pyrotechnics on board a vessel on an international voyage is correct? The vessel must carry at least 4 parachute rockets.
  5. Which is the most correct statement about pyrotechnics? A red hand flare keeps burning after it has fallen into the water.
  6. Which statement about pyrotechnics on board a vessel on a national voyage is correct? The vessel must carry at least 4 parachute rockets.
  7. You are entering a marina and see a vessel lying close to the entrance flying flag B of the International Code of Signals. What do you do? I may enter the marina, but must take care and avoid getting too close.
  8. The marina office where you berth (a sailing yacht) tells you to moor alongside another vessel (a sailing yacht identical to yours) because the marina is crowded. How do you moor your boat? I moor alongside "bow to stern".
  9. As you enter Herzliya Marina, turning the wheel has no effect at all on the boat's steering. What is your immediate option? I fit the emergency tiller to the rudder stock.
  10. You are on passage from Ashkelon to Haifa in a 14-metre boat drawing 2 metres, 2 nautical miles off the coast. Off Tel Aviv Port a south-westerly wind of 25 knots starts to blow. What do you do? I carry on north to shelter in Herzliya Marina.
  11. What are the first things to do when you discover flooding on board? Taste the water, start the pumps and close the openings.
  12. Your 19 m boat is moored alongside the fuel berth in a marina. The wind is pressing you hard against the berth and you want to leave. What could be a solution? I will use a bow spring with a fender at the bow and go ahead on the engine.
  13. You want to moor Mediterranean-style in a harbour in Greece. Where can you find information about the harbour and the berth? In the pilot book, on nautical charts and from friends who have sailed in the area.
  14. Your boat is moored in a marina to a "dead anchor" (a sinker) by a "mooring" line (lazy line). What is the danger when you leave? That the engine cannot be put in gear until the line has sunk.
  15. In the cardinal buoyage system you see a yellow-and-black buoy with this topmark above it. On which side should you pass the buoy? Pass to the west of the buoy.
  16. As you approach a marina you want to furl the jib, but the jib furler will not turn. What can you do? Answers a and c are correct.
  17. While berthed in a marina you receive a warning that a very strong wind (Beaufort force 9) and high waves are expected before dawn. What do you do? Answers b and c are correct.
  18. Approaching Herzliya Marina from the west, you are sailing in a 2 m westerly swell. How high do you expect the waves to be near the entrance, and what do you do? There will probably be high waves at the marina entrance; I will try to time my entry for a lull between the waves.
  19. Approaching a marina entrance by day, you see a vessel stopped in the entrance showing these day-shapes: ball, diamond, ball. On her starboard side you see two black balls. What do you do? She is restricted in her ability to manoeuvre by her work; passing on her starboard side is prohibited, so I pass her on her port side.
  20. Over the VHF you are told to berth in the marina using the method called "Mediterranean mooring". So you will moor: With an anchor or a mooring buoy at the bow, and the stern to the quay.
  21. You are on a sailing yacht with her sails furled. A north-westerly wind of 20 knots is blowing. In the entrance to Herzliya Marina, between the breakwaters, the engine suddenly stops and you cannot restart it. What will you do? I will set one of the sails so as not to be left without propulsion.
  22. In the cardinal buoyage system, what should you do when you see a sequence of 9 quick flashes? Pass to the west of the buoy.
  23. You are approaching Fethiye marina in Turkey to make your first entry. Which flags will you fly on an Israeli boat? The Turkish flag on the starboard side, flag Q on the port side and the Israeli flag at the stern.
  24. What are the requirements for pyrotechnic equipment? A red hand flare keeps burning even after it has fallen into the water.
  25. You are about to make a Mediterranean moor in a marina crowded with moored boats. Your boat is 12 metres long (anchor at the bow), the depth is 7 metres, the anchor rode is 70 metres long, and a strong crosswind is blowing on your starboard bow. Where will you drop the anchor? I will drop the anchor straight out from my berth, at right angles to the quay and as far from it as possible.
  26. What information can you find in a "pilot book"? Most of the information needed for navigation and route planning in the area concerned.
  27. In the cardinal buoyage system you see a yellow-and-black buoy with the following black topmark above it. On which side of the buoy should you pass? Pass to the east of the buoy.
  28. You are on a vessel leaving Herzliya Marina at night. Which lights do you expect to see on the breakwaters, relative to your bow? Picture 74.
  29. A vessel flies the flag in picture 95 by day. What light will she show at night when in the marina? As shown in picture 13.
  30. Approaching a marina, you see a vessel lying in the marina entrance and flying flag B of the International Code of Signals. What will you do? I will enter the marina and avoid getting too close to the vessel, as a precaution.
  31. In the cardinal buoyage system, you see nine quick flashes in 15 seconds. On which side should you pass the buoy? To the west of it.
