come in contact with, and have the edges of the planks 



broke so as to make a leak*, which would not happen to 



a smooth-sided boat, neither can the uneven side move so 



■well through the water, on account of its various resist- 



ancesf. They have also this disadvantage, that if damaged, 



they require the skill of a professional workman to repair 



them. 



Advantai^es of xhe carvel buiU boats have the advantage of having

smooth sides and fair water lines, together with having the 



planks of an equal thickness all over the boat, which makes 



them less liable to receive injuries when meeting with other 



bodies, and more adapted to move in the water, by their 



fair sides and fair water lines. They are also more readily 



repaired : if a professional boat-builder is not at liand, it 



can be done by a common shipvi'right, or any workman that 



is used to wood work. 



ItsdLadvan- But they have also their disadvantages; in the first in- 



**S^^' stance they are under the necessity of being built of plank 



of a great thickness to stand caulking ; at the same time 



they require larger timbers, which makes them heavy and 



unfit for many uses, and also a great consumption of timber 



on account of the thickness of the plank necessary. They 



are also more subject to leaks from various causes than 



clincher-built boats. 



Neutral build- We will now look to tlie neutral system, and see if both 



'"^" their advantages are not united, and both the disadvantages 



got clear of. 



PI. IV, fig. 2, shows the section of the fore part of a 

 boat. The longitudinal slips are represented lighter colour- 

 ed, and placed over the joints where the edges of the plankg 

 meet; they must be rivetted on to each adjoining plank, 

 near the edge, in the same manner as clincher-built vessels, 

 with a sufficient quantity of blair, made of tar and flocks, 

 such as is in common use in the north of England, (or any

f This does not appear to be the fact. Clincher built vessels are so 

 superior to others in sailing, that, by an act of parliament passed many 

 jears ago for the prevention of smuggling, they were declared illegal be-
