Misc. Notes:
Company No: 47999; Thames Estuary Cruising Club Ltd. Incorporated in 1896. Dissolved before 1916
Engineering: Volume 3, 1897: “This is the new one class design of the Thames Estuary Cruising Club, a newly formed association which has its quarters at Grays, in Essex. The boat appears an excellent example of workmanship and fitting, and has been built, together with several other sister craft, by W. Berridge, of Southend. These boats are designed more for comfort — an excellent thing for a cruising club to keep in view — than for extreme speed, though they should be fast enough according to all but “pot-hunting ” form, and as they are all alike they will doubtless afford excellent sport in racing, as well as being good knock about cruisers. After all, it is closeness of the contest more than absolute speed which gives interest to a race. This boat is 17 ft. 6 in. over all, 14 ft. on the water line
