Where a boat-house is not used the boat must be removed from the water by means of a 

 car, skids or rollers and the boat secured in its stationary out-of-season position by blocking 



ings are known as channel buoys and 

 are situated in mid-channel. Steer close 

 to these on either side. These markings 

 mean the same on any style of buoy. 



The harbor or channel buoys are num- 

 bered from seaward, each harbor or channel 

 having its own system of numbering, 

 although the black or port buoys carry the 

 odd numbers, as I, 3, 5, and 7, while the red 

 or starboard buoys carry the even numbers 

 as 2, 4, 6, and 8. Spar buoys are placed 

 where the water is not greatly disturbed. 

 They are the most frequently used as they 

 are visible at long distances. Nun and can 

 buoys are built of steel and are used in the 

 more disturbed waters; the nuns mark the 

 starboard side of the channel, obstruction, 

 or mid-channels, and the cans mark the 

 port side, the colors indicating upon which 

 side they are to be passed. 



Gas buoys, bell buoys and whistling 

 buoys serve the same purpose and carry the 

 same message, according to color and num- 

 bering, with the additional advantage that 

 the bell buoy gives warning of its location in 

 a fog, and the gas buoy flashes its location 

 at night. 



On the chart, red buoys will be colored 

 red, with the number alongside, and black 

 buoys will be shown in black and numbered. 

 Danger buoys are colored with black and 

 red horizontal stripes, while mid-channel 

 buoys-will be marked black and white with 

 perpendicular stripes. The operator will 

 occasionally find buoys carrying a half num- 

 ber such as \}/2, 5H» etc., which merely 

 shows that a new buoy was placed after the 

 main string had been set. 



When running into shoal water the op- 

 erator will usually notice a heavy ground 

 swell; the water will take on a light green 

 color. Rocky bottoms with little patches 

 of sand between the boulders take on a 

 reddish color from the weeds or a deep 



Care should be taken to see that the shoring does not rest on any one plank in the hull, but 

 on several planks immediately over a rib to prevent damage to the support from sudden jars
