The Vanity, new catboat of Capt. Thomas Walker Pease, was launched from the yard of Manuel Swartz on Thursday morning with appropriate ceremonies.

Manuel Swartz, the well-known boat builder, near Steamboat Wharf, has just built for Capt. Manuel Sylvia, of Nantucket, a fine large cat-boat, which is to be named the “Helen,” and will be sailed by Capt. Sylvia. The boat was measured by the custom-house here this week and is 30.8 long; breadth 13.6; depth 4.5, and is to be equipped with a 10 h. p. Victor gasoline engine, and all modern gear. The boat is in every respect a fine product of the boat-builder’s art.

Manuel Swartz, the boat builder, has moved into new and enlarged quarters - the front end of what was formerly the Norton Bros. mill building. Mr. Swartz has much improved the building and will be better prepared than ever before to cater to his patrons.
