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.

Between sunset and sunrise or in times of restricted visibility, you'll need to switch your navigation lights on so others can see you.

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

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

Inflatable lifejackets are excellent, but they require a fair bit more maintenance than regular lifejackets. Take it in to get serviced regularly (or do it yourself if you are capable) and don't wear it again after it's been activated, unless you replace the gas cartridge first.

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

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.

Sailing vessels tend to have gigantic sails that will sometimes block out light. If you can't see the all-round white light, there's a good chance it's a sailing vessel.

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

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.

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.

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.

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.

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.

It is downright moronic to let a child go boating without a lifejacket. Keep them safe, fit them with a lifejacket at all times.

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.

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.

As is standard practice elsewhere, your blood alcohol level MUST NOT go above 0.05. Boat responsibly; go easy on the drink.

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.

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.
