similar to that on steel buoys exposed in the Bay for the same length of time. 

 Fouling organisms included green algae (heaviest in the splash-zone), barnacles, 

 tunicates, bryozoa, tube worms, and hydroids. The barnacles were compara- 

 tively few in number but large in size. The organisms were rather easily removed 

 (as they are from steel buoys) by high-pressure hosing with seawater. 



Hand Lay-Up Buoy. The hand lay-up buoy was still in very good 

 condition after about 4 years of service to the Fleet. There was considerable 

 superficial white staining by guano on the top and side (Figure 2). There was 

 also rust streaking from the steel mooring eyes and hardware used to secure 

 the fenders in place. The upper lateral fender, which had previously been torn 

 loose by impact and later wired back in place, was still providing good protec- 

 tion. The two test patches* made on the buoy side after one-half year of 

 service were also in good condition. Most of the reflective glass beads embed- 

 ded in the buoy coating had been lost above water, but many remained below 

 water.
