the thwarts, and are secured to their places by short bolts 

 driven througli the thwarts at the back of each hook, similar 

 to the bolts D and D, which secure the upper edges of the 

 pannelling. A side-view of one of these hooks is given by 

 fig. 4. Ihe platforms GG and GG, which are made in two 

 lengths of plank, so as to be readily lifted up, rest on ledges GG 

 and GG, which are nailed to th.e paniieiling, and are secured 

 from floating, when water is in the boat, by copper sliding-boits, 

 which shoot into holes in the ledges of the pannelling. 



Fig. 5 is a section of the boat, showing the delivering tubes 

 A A, with the casing or well around them for their security ; 

 also the mast as fixed in its step between them. On the out- 

 side of this section are several horizontal lines, which mark 

 the boat's draught of water in her various states. The lines 

 B and B show the draught witii the crew and her materials 

 on board. Tlie lines C and C represent the draught with the 

 same persons on board, but with the plugs out, and the water 

 inside the vessel being on a level with the v/ater without ; — the 

 vessel at this time being rested upon, or entirely borne up 

 from sinking deeper by the floating capacity within the boat. 

 The lines D and D show the draught under similar circum- 

 stances, but with seven extra hands on board. 



Fig. 6 is a ground plan of the mast-step, which is fayed close 

 down across the bottom of the boat, and there secured. The 

 circles represent the holes thi-ough it, which receive the tubes 

 and give them a firm ami steady security. The small scjuare 

 between them is the mortice-hole which receiver the mast, the 

 cUirk margin aroimd is a section of the well, and the dashed ob- 

 long is the extent of the step across the bottom of the boat. 



Fig. 7 represents one quarter of the vessel, and comprehends 

 a sufficiency of lines to exempliiy her form to a builder. 

 The general dimensions of the boat are 31 feet from rabbet to 

 rabbet at the stem and stern, and six feet beam fi-om outside to 

 outside ; the height from the keel-seam amidships being tvso 

 feet ten inches, and four feet two inches at the bow and stern. 



This liie-boat was launched on the Ith of Ajiril 1821, in 

 the presence of a large concourse of .s}>ectators ; when liie li)l- 

 lowing experiments were confi{led to the able management of 

 Mr. Benjamin llamblin, master ^oi" the iStevens, whose readi- 

 ness to oblige every (;ne with a view of the vessel, in her se- 

 vei'al stales, gave pleasure to all. 



In tiie first instance, the boat was rowed ilown the river, nearly 

 to tile Hallasl-wharf, and up again to the bridge, at Ipswich, by 

 six al)ie young seamen, in excellent style, v.hich iairly set forth 

 her ability as a row-boat. In this sli^te, with her crew of seven 

 men, and oiu' e\tra hand on lioanl, her gunnel aniid;^l)ips was
