Joly — On Floating Breakwaters. 383 



serving a clear entrance in fair weather, and to a floating 

 shelter, moored about a quarter of a mile off' the piers, as harbour 

 of refuge. There is a depth of four fathoms at this distance. 

 The shelter should consist of two separate breakwaters, moored 

 so as to afford shelter from north round by east to south, and 

 having an entrance between them opening east. The breakwater 

 should be lit, and be guarded by a bell-buoy. Behind these 

 breakwaters there would be perfect security for the small vessels 

 of Arklow, which might be prevented from returning to harbour 

 owing to sudden silting of the bar. The short and dangerous sea 

 which rapidly gets up in the bay in rough weather would be 

 excluded from the space enclosed between the breakwaters, and 

 here also there would be considerable shelter from on-shore winds.
