 length. They often have an atap roof for shelter amidships ; in 

 these the space available is increased by building out over the

outrigger booms upon a longitudinal pole laid athwart the booms 

 a foot or so outboard on each side. 



In all but the smallest outriggers four crutches are inserted in 

 the booms about a foot outboard, to take spare bamboos, poling 

 sticks, etc. In many, these crutches have a faint suggestion in 

 their shape of a bird motif and in a few this is emphasized un- 

 mistakably (Fig. 40).

By means of two transverse poles lashed below the forks 

 of the forward and aft pairs of crutches respectively, each 

 further supported by two nearly upright stays stepped on two 

 projecting cleats inside the canoe, a simple framing is made 

 (Fig. 40), which by the addition of a king post in the centre at each 

 end and of a longitudinal ridge pole, can be used when necessary 

 to support an atap (palm leaf) roof.
