The submarine chaser is 

 eighty feet long, with a 

 twelve-foot beam. The 

 cruising radius is seven 

 hundred miles at twenty- 

 two miles per hour and 

 fifteen hundred miles at 

 fourteen miles per hour 



The motors are of five 

 hundred horsepower and 

 the sea-keeping qualities 

 are such as to allow for a 

 sea patrol of ten days 

 duration. The English 

 channel is regularly pa- 

 trolled by these boats
