$62 Description of a secure Boat, or Life Boat. 



clincher-built boats, as the timbers need no greater notches; 

 but with this difierence, that these timbers will catch the 

 slips that are riveted over the joints of the planks each way, 

 and so the timbers and slips will brace one another, and add 

 an additional strength ; but in the clincher-built boats, the 

 timbers catch the laps of the seams only one way, and con- 

 sequently form no brace whatever. 



All I need to explain further on the neutral system is its 

 Application. It can be applied to all open boats, of what- 

 ever form or use, to all coal and other barges, lighters, or 

 any vessels used in rivers or canals, and also to all large cut- 

 ters and luggers, which are now clincher-built. 



Explanation of Plate VIII. Fig. 1, 2, 3, 4. 

 Fii!;. 1, is a bird's-eve view of the boat, showing the pro- 

 jecting balance bodies, or hollow sides a h, one of which, 

 G, is left open to show the partitions which are placed op- 

 posite to each timber, and are water-tight; by this means 

 if one or more should be broken, the rest would keep the 

 vessel buoyant. These partitions gradually lessen towards 

 each end, where the planks unite, so as to make a similar 

 appearance to any other boat when in the water. 



Fig. 2, shows the depth and form of the cells or hollows, 

 as they appear in a section of the boat ; also the manner in 

 which the slips are placed over the joinings, or seams of the 

 planks. 



Fig. 3, is a perspective view of the boat, in which a h 

 show the projecting balance bodies, or hollow sides, which 

 would render the boat buoyant if her bottom was staved in. 

 c, the lower part or body of the boat, from which the pro- 

 jections commence ; dy the keel. 



Fig. 4, shows the manner in which the planks or timbers 

 of the boat are united ; ef, are two planks of the boat ; g^ 

 the slip of wood placed over them, and secured to them by 

 the rivets li h. 



The section Fig. 2, will best explain the nature and 

 utility of the self-balanced boat. The balance bodies form 

 two separate holds, to put any thing in, such as provision, 

 arms, Sec, which are wanted to be kept dry, having locker 



lids^
