Question 1

When approaching a hazard or narrow entrance in a tidal stream, why is judging the "set" (direction and rate of tidal flow) important, beyond just knowing the time of high or low water?

Accepted Answer

A tidal stream can push a vessel sideways relative to its intended track even while the boat itself points straight at its destination — misjudging the set can carry a vessel off the safe course and into a hazard the skipper never intended to approach, which is why watching for signs of set (transits, drift relative to fixed marks) matters continuously, not just at the planning stage A plotted course that accounts for tide at the planning stage is a starting point, not a guarantee — actual tidal behaviour can vary from predictions, and continuously checking your actual track against fixed references (transits, bearings) is how you catch and correct for set in real time rather than discovering the error only once you're somewhere you didn't intend to be.

Question 2

What is a common and avoidable mistake when approaching a berth, particularly for less experienced skippers?

Accepted Answer

Approaching at too high a speed for the conditions and available sea room, and not having fenders and lines rigged and ready before the final approach — both leave far less margin to react if wind, current, or another vessel changes the picture at the last moment Excess speed on the final approach and unprepared lines/fenders are two of the most common, entirely avoidable contributors to a difficult or damaging berthing — both are simple to fix with preparation (rig fenders and lines early, approach at a genuinely controllable speed) and both directly increase the margin available to react if something doesn't go to plan.

Question 3

Why does overloading a small craft (too many people, too much gear, or both) matter more than it might on land?

Accepted Answer

Extra weight reduces freeboard and stability, changes how the boat responds to waves and manoeuvring, and can push a small craft dangerously close to (or below) its safe carrying capacity — the effect is proportionally much larger on a small boat than the same relative overload would be on a larger vessel or a road vehicle A small craft has comparatively little reserve buoyancy and stability margin to begin with, so extra weight — whether people or gear — has a proportionally much bigger effect on freeboard, stability, and how the boat handles in waves than the same relative overload would on a larger vessel. Checking and respecting a vessel's rated capacity is a real safety matter, not just a guideline.
