etc.) should be examined carefully as a likely spot for a leak to occur.
i)
A passing small boat may be able to assist by carrying out your anchor so that you can pull yourself free. If
the other boat operator elects to attempt a tow, see Sections 4.4.2 and 4.4.3.
j)
Continue to inspect the hull as you pull free, being hard aground may be preferable while you control leaks
spotted as you get into deeper water.
k)
If it is not possible to pull free, start your engines one at a time. Observe for leaks. Observe cooling water
flow out exhausts. Inspect for unusual noise or vibration. Check your gauges. A rapidly rising temperature
gauge may indicate a water pick up is plugged.
l)
Rotate shafts slowly one at a time (to take the boat in the opposite direction it was going before the
grounding). Observe for leaks around shaft stuffing boxes. Listen for rubbing or other unusual noise.
m) Turn the helm to ensure rudders move freely.
n)
Slowly apply power one engine at a time and observe for noise, vibration or indication of overheating.
o)
Work free, continuing to observe for conditions which might arise as the hull works its way to clear water.

LEAKS
Leaks occur in various degrees of potential danger to the vessel. Some drips from fittings are easily corrected
while a hole caused by striking a submerged object may be difficult to control. The following sections provide
basic leak control techniques.
5.2.1
HOSE LEAKS
a)
If a leak occurs at a hose clamp, tighten the clamp slowly until the leak stops. Do not overtighten or the clamp
might break. In addition, hose which has aged may have softened. Tightening the clamp may cause the end
to splay out and the leak to worsen. A second hose clamp may be needed to stop the leak.
