BSAC SPORTS DIVER ACTUAL EXAM
PAPER 2026 FULL QUESTIONS AND
CORRECT ANSWERS GRADED A+
●● What's the initial limited depth for a sports diver? Answer: 20m
●● What's the progressively extended depth of a sports diver? Answer:
35m
●● Is a neap tide small or large? Answer: Small
●● Is a spring tide small or large? Answer: Large
●● What causes a neap tide? Answer: When the Moon is at a right angle
to Earth and the Sun, creating the least amount of gravitational pull in
one direction, creating weak tides.
●● What causes spring tides? Answer: The gravity of the sun and moon
pull in the same direction, creating strong tides.
●● Neap tides coincide with what? Answer: The quarters of the moon
●● Spring tides coincide with what? Answer: New and full moon
,●● What's the average tide cycle in most places? Answer: 12 hours
●● How many tide cycles in a day? Answer: 2
●● How many high tides in a day? Answer: 2
●● How many low tides are there in a day? Answer: 2
●● How many times do spring tides occur in a lunar month? Answer: 2
●● How many times do neap tides occur in a lunar month? Answer: 2
●● What's the tidal range? Answer: High water - low water
●● What's slack water? Answer: At the tides turning point, when the
water speed is at its slowest.
●● What can make diving on a static site (e.g. a wreck) safer? Answer:
Diving in slack water
●● What is ground swell? Answer: When wind causing wave action on
the surface can be felt on the sea bed.
, ●● When is ground swell the roughest? Answer: When the surface winds
go against the tide/stream/current flow.
●● Is an incoming or outgoing tide better for visibility? Answer:
Incoming
●● What are five factors that can affect visibility? Answer: - bad
weather
- tides
- being close to river estuaries
- lots of phytoplankton + zooplankton (most likely to be a problem in
spring in most places.)
-disturbance by divers.
●● What's a thermocline? Answer: Sudden change in temperature, may
look oily/ shiny and produce a change in visibility
●● What can you do to reduce the effect of glare on the surface (as a
boat crew member, not a diver?) Answer: - wear polarised sunglasses
- position the boat with the sun behind you
●● What are four things you should take into account when doing a risk
assessment? Answer: Conditions, depth, breathing gas and equipment
