航海 交通Capt. King, from Demarara, was invaded by the gale on the evening of the 6th, in lat. 21° 51', and his vessel was thrown on her beam ends. He was forced to cut away her main-mast. Lost a man, who was washed overboard. . . . Capt. Mood, on a voyage from Alexandria (Virginia), to St. Mary's (Georgia), was, on the night of the 7th, in the Gulf Stream, to the eastward of Charlston: the wind there was east-north-east, and so hard as to throw his vessel on her beam ends. She lay several hours in this situation. Several of his crew were washed overboard.
1808 Richard Hall Gower. On the Theory and Practice of Seamanship. It often happens that by a sudden squall of wind a vessel is thrown over upon her beam ends, without a prospect of recovering her erect while she remains upon the same tack, therefore attempts are made to veer her; but as the rudder lies along the surface of the water it becomes useless, and as the sails are either blown from the yards, or become unmanageable, recourse is had to cutting away the main-mast and mizen-mast, that the ship may veer under the fore-mast:-a most desperate expedient, particularly if the ship is far distant from port!

From Middle English beem, from Old English bēam (“tree, cross, gallows, column, pillar, wood, beam, splint, post, stock, rafter, piece of wood”), from Proto-West Germanic *baum, from Proto-Germanic *baumaz (“tree, beam, balk”), from Proto-Indo-European *bʰew- (“to grow, swell”). Cognate with North Frisian Boom, buum (“tree”), Saterland Frisian Boom (“tree”), West Frisian beam (“tree”), Cimbrian pome, póom, puam (“tree”), Dutch boom (“tree”), German Low German Boom (“tree”), German Baum (“tree”), Luxembourgish Bam (“tree”), Mòcheno pa'm (“tree”), Vilamovian baojm (“tree”), Yiddish בוים (boym, “tree”), Danish, Norwegian Bokmål, Norwegian Nynorsk, Swedish bom (“beam”), Icelandic baðmur (“tree”), Gothic 𐌱𐌰𐌲𐌼𐍃 (bagms, “tree”), Albanian bimë (“a plant”). Doublet of boom. The original English meaning of beam ("tree") is preserved in some compound words such as quickbeam. The verb is from Middle English bemen, from Old English bēamian (“to shine, to cast forth rays or beams of light”), from the noun.
