Less time will be spent in ports for over- hauling and repairs. The expense for supplies, such as oil, packings, waste, etc., will be largely ehminated. There will be no trouble from oil in the boilers. Strain and vibration will be greatly reduced, due to the elimination of reciprocating masses. That many owners, ship builders, marine engineers, and naval architects have been convinced by the data which we have been able to present in support of the above statements, is shown by the fact that over 150,000 hp. of De Laval Marine Gears are now under construction. Full data for your consideration in connection with any boat which you are planning or building will be supplied by our Engineering Department upon receipt of particulars concerning horse power, displacement, speed, boiler pressure, num- ber of screws and general character of vessel and service in which it is to be used.
