Pilot Boat 

 2nd.Poa. 



A vessel hove-to for a pilot, Figure 

 12, should distribute oil from the 

 weather side and lee quarter. The 

 pilot boat runs up to windward and 

 lowers a boat, which pulls down to 

 leeward and around the vessel's stern. 

 The pilot boat runs down to leeward, 

 gets out oil bags to windward and on 

 her lee quarter, and the boat pulls 

 back around her stern, protected by 

 the oil. The vessels drift to leeward 

 and leave an oil slick to windward, 

 between the two. 



Towing a vessel in a heavy sea, oil is of the 

 greatest service and may prevent parting the 

 hawser. Distribute from the towing vessel, for- 

 ward on both sides, Figure 13. If used only aft, 

 the tow alone gets the benefit. 



At anchor in an open roadstead, use oil in 

 bags from jib boom, or haul them out ahead of 

 the vessel by means of an endless rope rove 

 through a tail block secured to the anchor chain.
