The general arrangement of the I hydroplanes with respect. to the rest of the boat is shorin in Figs. 1, 5 and 65 from which it will be seen that the hydroplanes. 13 and their actuating mechanism are supported in acast1ng21 which 15 mounted on supporting beams24 resting uponl'the hull 22x-of the Fig. 1, so that the casting is i This casting interrupts the continuity of lengthwise thereon. the walls ofthe super-structurev 4 as shown in boat and. extending the super-structure, and extends beyond the line. thereof a sufiicient distance to permit the -freemotelnent of the planes 'on' their horizontal and vertical axes.

The steering operation is "effected means of the steering shaft 1 which extends'lengthwise of the superstructure supported in bearings tinned. to a convenient point within thevessel, Where itconnects with the steering wheel; This shaft is..rconnected. through .a'nniversal coupling 3 to a worm gear?- is a section onthe. line 2-2 of Fig. 1 showing particularly the.

The sectorsfi engage w th bevel gear sectors 11 secured to the shafts 12 of the hydroplanes by keys or pins. By means of this connection the turning of shattl results in a corresponding turning.moyement of the.

hydroplanes on theirhorizontal'axes;By v virtue o't-the fact that the Wormis'capable f of turning the hevelasector's While the re-- vere operation is not possiblegthe hydro-.-
