An Engine-Carrying Fin for the Power-Boat 



A device for conserving floor space on the boat and 

 for enabling the boat to turn in its own length 



The engine-containing fin principle applied to car floats. These large, clumsy floats can be 

 handled as easily as a light motor-boat, and the need of a tug is thus done away with 



A LL the captains who sail the briny 

 J-\ deep are not satisfied with their 

 ships. Captain Samuel Golden was 

 not so pleased with ships as he found them 

 that he did not think they could be im- 

 proved. Therefore, he thought out meth- 

 ods of improving power-boats. So far the 

 captain has built three boats, all designed 

 along the same lines. 



The last one, known as the "Shib 1 1" is a 

 forty-foot houseboat equipped with a four- 

 cylinder 28-hp. engine which operates at 

 about 500 revolutions a minute. The 

 peculiarity of the 

 construction lies 

 in the fact that 

 the boat is equip- 

 ped with a fin 

 which is about 

 twenty feet in 

 length, twenty- 

 seven inches in 

 width at its wid- 

 est part and 

 tw e n t y-s i x 

 inches deep. The 

 engine is built in 

 this fin. The 

 propeller is an 

 ordinary three- 

 bladed side pro- 

 peller, twenty- 

 two by thirty- 

 inch pitch. The 

 rudder is smaller 

 than those used 

 in other boats of 

 her size. 



The entire fin 



A new type of boat which 

 contains the engine. The 

 water. This boat may be 



is submerged. The water flows around the 

 extreme lines of the fin without any suction. 

 Therefore, the full surface propeller blades 

 are available for pulling as well as thrusting. 

 The thrust from the propeller cannot rise 

 into the air. No air can reach the wheel. 



The short narrow fin and the position of 

 the rudder and propeller make it possible to 

 steer the boat with great accuracy. One 

 advantage in this construction lies in the 

 fact that this type of boat may be used for 

 many purposes, such as for tugs, lighters, 

 pleasure boats, speed boats, ferry boats and 

 power life-saving 

 boats. In 

 crowded harbors 

 it is very neces- 

 sary to be able to 

 handle ships 

 without -mishap. 

 The invention of 

 Captain Golden 

 makes ft possible 

 to turn any ves- 

 sel in its own 

 length and makes 

 steering far more 

 accurate than it 

 is with ordinary 

 boats. 



The size of the 

 fin is in propor- 

 tion to the size of 

 the boat. In the 

 case of a float for 

 railroad cars the 

 finislargeenough 

 to be a good-sized 

 engine room. A 



has a short narrow fin that 



propeller is always under 



steered with great precision
