Comparison Table of Lake & Holland type Submarines

             (The following is a Lake Torpedo Boat Co. table published 1900-1904. )

   “Table showing constructive features and capabilities of Submarine Torpedo Boats, taken from the working specifications of the “Lake” Boat now building at Bridgeport, Conn., and from the Official specifications of the submarine boats now in course of construction for the U. S. Government: “

“LAKE” BOAT

Length Overall………………………………...65 feet        

Breath of Beam ……………………………….11 feet

Displacement Afloat ………………………..115 tons

Surface Buoyancy …………………………...55 tons

Engine Horsepower: 250 applied directly to shaft

Battery Capacity: 75 horsepower for 4 hours

Twin Screw

Hull sufficient strength to submerge 150 feet

Armament: 3 Whitehead torpedo firing tubes

Means of submerging: Admitting water ballast, use of hydroplanes & hauling by anchor weights

Means of surfacing by: Discharging water ballast by compressed air, power or hand pumps; hydroplanes when underway; lowering anchor weights; & releasing emergency drop keel.

Fuel carrying capacity: 1400 gallons

Estimated surface speed: 10 to 11 knots

Estimated submerged speed: 7 knots

Means of traveling on the bottom

Submerges on level keel

Means to enable divers to leave and enter vessel while submerged

Automatic & positive maintenance of trim

Means to measure distance traveled when submerged

Invisibility in a semi-submerged condition

Capability of steering long & correct courses

Automatically controlling depth of submergence

Means of cutting cables, mining & countermining

A water tight super-structure affording deck space & sufficient buoyancy to make her seaworthy & also afford space for storage of fuel, air, tanks, etc.

Automatic drop keel & other automatic features to prevent submerging below a safe depth.

Gasoline fuel carried in super-structure where escaping gas or leakage would not injure crew

Ample officers’ and crews’ quarters with cooking and sleeping facilities.

Provision for escape of crew in case of partial disablement of vessel while submerged.

“HOLLAND” BOATS
