sport fish and drawing birds away from the protected facilities. The 

 harbormaster cited the FTB as also having a positive effect on boaters' 

 comfort. This effect was most vividly apparent by an immediate increase 

 in slip rentals and transient boaters visiting the harbor. In meeting its 

 design goals, the FTB had a high performance. 



Project Analysis: This project met with considerable success despite some 

 severe flaws in its coupling, flotation, and anchoring systems. The 

 success which was achieved is testimony to the City's persistence in 

 correcting the faults and constantly monitoring the structure. The 

 coupling material should have been rubber conveyor belting fastened by 

 galvanized steel bolts. Proper flotation would have been met if 

 polyurethane foam had been poured in most of the tire crowns. The final 

 anchoring system used appeared adequate, particularly since lake 

 conditions were partially dampened by the submerged inner wall before 

 interacting with the FTB. The harbormaster's observation of increased 

 revenues as the end result of the project was an important one, for it 

 does illustrate that an FTB can bring in money, in addition to reducing 

 repair costs to wet-stored boats. Finally, this case history highlights a 

 valuable use of this type of breakwater- -as a temporary structure before 

 a permanent breakwater can be planned and installed. In this capacity, 

 the FTB was most successful.
