I is the length in metres of breakwater frontage 



restrained by the mooring line (10.72 m for the 

 central line, 5.36 m for the corner line). 



e is the angle between the mooring line and a 

 perpendicular to the front face of the FTB. (0 



degrees for the central line, 45 degrees for the 

 corner line) 



The formulation of Equation 6 neglects current or ice-induced mooring 

 loads; it is appropriate for the La Salle Park FTB during the boating 

 season. 



Model tests of Goodyear FTB's (Harms and Bender 1978) and of 

 Pipe-Tire floating breakwaters (Harms et al . 1981) revealed that F^j 

 does not vary substantially with B/Df Mooring loads increase with 

 increasing values of L/D^, H/D^ and D^/h. 



Preliminary analysis of the dimensionless parameters F^j 

 versus H^/D^ showed that the use of tires with diameters larger than 

 0.64 m would result in the prediction of smaller mooring loads for the 

 same incident wave height. This disagrees with expectations. More data 

 is needed to quantify the effect of tire diameter on mooring loads. 

 Accordingly, the analysis of mooring loads has been done dimensional ly. 



The dominant variable affecting mooring loads at the La Salle 

 Park FTB is H^- There are 65 records in which H^, 2l 30 cm (see 

 Tables 2-4). For these records, the dimensional peak mooring loads per 

 unit length (Fmax^°^^^/^ '^^^^ ^^^'^ plotted against H^, in Figure 13.
