11.6.2.Towing and Handling warps and doors
A smooth run of warps from the winch to the gallows is necessary. The required blocks and sheaves must be arranged in the working area to permit easy spooling on the winch and a smooth run over the gallows with minimum changes in the direction.
A pair of gallows to be mounted at each side of the working deck at the aft and alternative method for towing support is to have a gantry structure which will leave the working desk completely free of towing blocks.
