The other angularly extending end portions 36 of the
pivot links 79 extend through suitable lugs 87 secured to
the side walls 88 of the boat in any suitable manner. The
brackets 87 extend rearwardly at an angle from the side
walls 88 so that the side wings move rearwardly from the
front section 75 of the deck as the hinge links 79 are
pivoted inwardly and then downwardly from the upper
raised positions illustrated in broken lines in FIGURE 5
to the retracted positions illustrated in full lines in FIG
URE 5.
The outer sections of the side wings are provided with
incurved edge portions 59 which form a rearwardly open
ing recess in which are receivable the forwardly extend
ing side ?anges 90 of a windshield 91.
The windshield is secured to the bottom wall 60 of the
front section by a pair of hinge links 92 whose lower
angularly bent end portions 93 extend through suitable
apertures in the brackets 94 secured in any suitable man
nor to the bottom wall 60 of the front section and whose
of rubber or the like may be inserted between the recess
formed by the incurved portions 89 of the outer sec
tions of the side wings to be engaged by the ?ange 90.
The sections of each side wing may be held in the
extended positions illustrated in FIGURE 2, wherein they
form a shelter by any suitable means, ‘such as a strap
bar 104 secured to the two sections by means of screws
105 which extend into suitable threaded bores or sockets
provided in the main and auxiliary sections of the side
wings.
The side wing sections are triangular in shape sloping
rearwardly toward the rear of the boat whereby the nar—
row end portions ‘thereof are disposed outwardly of the
seat 48 and beneath the side sections of the deck. The
side wing sections may be provided with windows 99,

the windshield and the bottom of the boat by the brackets.
The side wings and the windshield may be moved from
the retracted positions illustrated in FIGURE 5 to the
their retracted positions illustrated in F'EGURE 5, the side
wings are moved outwardly to their extended positions
and the inner sections are pivoted outwardly and secured
in the extended positions illustrated in FIGURE 2 by
means of the straps 104. The front section of the boat
is then pivoted in a clockwise manner to the position illus
trated in FIGURE 2 wherein the now lower edges of
the inner sections of the side wings rest upon and abut
