Shallow Water Dangers; Running Aground - Chris-Craft Lancer 20 Owner's Manual

Safety and Operations

Shallow Water Dangers

The minimum depth of water you are able to run your boat is determined by several factors. The draft is
affected by the loading of the boat including the fore and aft trim, the propeller size and even by the salin-
ity of the water. When your boat is fully loaded, measure the maximum depth from the waterline to the
deepest point and note the number. It is the owner/operator's responsibility to maintain a comfortable mar-
gin over the bottom.
Should you run aground, visually check for water intrusion. If serious damage has occurred, it may be pru-
dent to stay aground until the damage can be assessed and controlled. After re-floating, check the running
gear for damage and feel for any unusual vibration. Perform a thorough inspection after trailering the boat.

Running Aground

Engine cooling intakes are located under the boat. Ensure intakes
are free and clear of debris. Do not start the engines if intakes are
plugged.
If you encounter shallow water and run aground:
1. Immediately place the transmissions in neutral.
2. Ensure everyone has, and is wearing, a PFD.
3. Perform a head count. Confirm everyone is present and accounted for.
4. If possible, inspect the hull, propulsion, and steering systems for damage.
5. Inspect for flooding and/or leaks.
6. If the vessel is undamaged, decide on an appropriate course of action:
– Determine the water depth and the type of obstruction you are lodged on: sand, mud, rock, etc.
– Is it possible to dislodge the vessel?
– Do you need to lighten the load by removing passengers or equipment?
– Is it possible to push the vessel off the obstruction?
– Is it possible to use reverse thrust to free the craft?
– Determine tide, current, and wind velocity. Will they help or hurt your situation?
7. If necessary, seek assistance from any nearby vessels and/or signal for help using an appropriate signaling
device.
8. If damaged it may be safer to leave the vessel aground and seek professional help.
