and pre-positioned fittings in the deck. When transporting the rotary tiller mixer aboard such vessels, use of

the onboard restraint equipment is considered adequate, and the vehicle will require no further blocking or

bracing.

6-5. Barges and Lighters

When the rotary tiller mixer is to be moved by barge or similar lighterage to or from vessels secured to piers or

at a sheltered anchorage, blocking and chocking materials are required. When the vehicle is to be moved

extended distances or through rough waters, tiedown restraints also must be used.

6-6. Landing Ships, Landing Craft, and Amphibious Vessels

When the vehicle is to be moved extended distances or through rough waters, blocking and tiedowns must be

used. Usually the vessels are equipped with a turnbuckle with a sheep's foot on one end that fits into a deck

cloverleaf, where not provided, a suitable substitute may be used.
