Navigation Lights: Must be maintained in perfect order so they will operate when required and will not accidentally illuminate at an inopportune time. Never give the enemy a light to shoot at. There were several instances where PT blinker and signal lights flashed on while in enemy territory. Hence, it is urged that proper care be taken, particularly in keeping switches and wiring dry and waterproofed.

Search Light: Be sure the "safety", provided in the circuit, is in good condition and is in the "off" position except when in use (to preclude accidental lighting). It can be very embarrassing.

Towing Gear: Also called "bridle and pendant". Keep it in good shape. Grease your wire rope and shackles. Paint the towing eye or ring to prevent corrosion and rust. You can't paddle or sail a crippled PT with any degree of speed or accuracy. Towing rigs have saved boats and men many times in the combat areas. You will learn to depend on it.

Canopy: A large canvas, which looks like a sheik's desert abode, covers the forecastle in the manner of a huge tent. It is the joy and comfort of every boat in off-patrol hours. Waterproof it. Camouflage it. Roll it up when stowing it, rather than creasing it, for creases make it crack and soon you have a leaky, uncomforting canopy.

Toe Rail: Is used for securing fenders and cargo net. It is a necessity in tying down the boat awning while at anchor. Prisoners can be secured to it, thus making the forecastle an ideal brig.

Sampson Post: Is indispensable in anchoring. Like the bullnose, never allow it to get loose. If you lack a towing bridle the Sampson post will suffice.
