(on at least some piers of each new marina welcoming live-aboards) suitable for transferring 

 the pumped out effluent into the landside sewer system may be necessary. Technical 

 problems involved in such systems need to be worked out; in time, another utiMty line may 

 be required. 



Locker boxes are not only used by sUp renters for gear storage, but often provide 

 structural support for electrical fixtures or hose bibbs. The boxes may be located in the 

 knees of floating systems (Fig. 112) or in some out of the way spot on decks of fixed 

 systems (Fig. 113). Some are custom made of plywood or sheetmetal, but manufactured 

 fiberglass boxes suitable for most sites are usually available for less cost and are more 

 durable in a marine environment. Some marinas require tenants to furnish boxes, but for 

 uniformity the modern trend is toward the initial installation of all locker boxes as an 

 integral part of the system. This is imperative if locker boxes support utility outlets and 

 light standards. Some are available with a conveniently located low-wattage Ught that not 

 only illuminates the power outlets and locker interior but also keeps an ambient 

 temperature, thus preventing condensation and resultant mildew or corrosion of stowed 

 gear. Many boaters use the tops of locker boxes as workbenches; if the lid is not already 

 suitable for this purpose, a special removable overhd cover can be devised for patrons that 

 use them for workbenches.
