If you find yourself on course for a head-on collision, turn to your starboard (right-hand) side. Both vessels must do this to avoid a collision.

A confusing question, but easy to answer once you understand what direction the other boat is headed. The green sidelight goes on a vessels starboard (right-hand) side. The red port sidelight on the other side.

We can't see the red port sidelight, so we must be looking at the right side of the boat. That means you are on their right.

Vessels must give way to their right. This means the other vessel gives way to you.

Drifting is when you are not anchored but are still moving along the water. You're still underway.

So, if you are underway at night, switch on both sidelights and your all-round white light.

On the water, give way to your right. As the red vessel is on your right, keep clear; take substantial action to keep well clear

Because we can see both side lights and the all-round white light, we can determine that we're on course for a head-on collision.  (You usually can't clearly see the sidelights from the rear of a boat)

As such, both vessels should turn to their starboard (right-hand) side.

You're the skipper, you're responsible. If you think there's only one thing to look out for, you're gonna have a bad day.

Remember the phrase, "Upstream, Red Port Left". When going upstream, the red port marker is on the left hand side of your vessel.

Remember the phrase, "Upstream, Red Port Left". Using this phrase, we can determine that the red port marker is on the left, and the green starboard marker is on the right when going upstream.

Now, as this question asks about downstream, the markers are now kept on the opposite side. So instead of red being on your left, it's now on your right.

Remember the phrase, "Upstream, Red Port Left". Using this phrase, we can determine that the red port marker is on the left, and the green starboard marker is on the right when going upstream.

Now, as this question asks about downstream, the markers are now kept on the opposite side. So instead of red being on your left, it's now on your right.

After sunset or in times of restricted visibility, you'll need to switch all of your navigation lights on. The red & green sidelights and the all-round white light need to be displayed in these situations.

Although it'd be awesome, we don't have eyes in the back of our heads. It's the duty of the trailing vessel to determine that overtaking is safe, and there is plenty of room to do so in a safe, responsible manner.

You are limited to the speed posted on these signs in the direction indicated. Here, we're limited to 4 knots in both directions. Let's take it slow.

Remember the phrase, "Upstream, red port left". If you know the what side the red port marker is to be kept on, the green starboard marker is simply the opposite.

At night, you can't tell if a non-flashing white light is a torch, car headlight or someone playing on their phone. Let your imagination run wild, it can be almost anything.

If you don't wear your lifejacket, it cannot save your life.

Powered vessels have much more control of their steering and speed compared to a sailing vessel, which is largely at the mercy of the winds and currents.

Any persons or apparatus being towed will share the same distance off rules as the boat they are being towed from. The trick for this question is not the towed person, but the person in the water, which is 60 metres at any speed.

Remember the phrase, "Upstream, Red Port Left". Using this phrase, we can determine that the red port marker is on the left, and the green starboard marker is on the right when going upstream.

Now, as this question asks about downstream, the markers are now kept on the opposite side. So instead of green being on your right, it's now on your left.

Boat responsibly and go easy on the throttle. If a sudden danger were to present itself, you should travel at a speed where you have enough time to safely avoid it.

Any persons or apparatus being towed will share the same distance off rules as the boat they are being towed from. The trick for this question is not the towed person, but the other vessels and structures, which is 30 metres when doing 6 knots or more.

6 knots - 30 metres
