Thetransom i_2) is a steel casting bolted tothe side frame at each end with the centerplate dropping down between the twocross-pieces and braced on each side bythe transom bases (29 and 30). The pedes-tals are of cast steel bolted to the side X bracing for the pedestals, but also tri-angulating the bracing, and so securingthe maximum rigidity. The bottom of thepedestal legs are tied together on eachside by the usual pedestal tie, which arein turn fastened together by the crossties (7).
