It is usually a nightmare to get an eighty-foot mast under a sixty-foot bridge. Usually, the only way is to de-mast the boat, which is a major undertaking for a forty-foot ketch. Man’s ingenuity never ceases to amaze me.
Two bags or “balls” are filled each with a ton or water and hung from the two masts of the ketch. By steering the boat sharply to port or starboard, the balls swing outwards and cause the boat to heel over. The boat is kept at the angle within which the ballast in the keel prevents capsizing. The heel is maintained by letting the weights go down to increase the proportional weight on the mast heads. Thus the boat stays heeled over even when it is steered in a straight line, and the heeling angle is under full control. The boat makes it under the bridge with only inches to spare.
If anyone recognises the music, please let me know what it is.
