Transformation of a US Navy submarine chaser into a palatial sea going craft was the unique work lately accomplished when Conquista was turned over her owner Brooks Gifford of Pasadena. The sale of submarine chaser No 296 been made earlier in the by Percy E Wright, a consulting mechanical engineer of Seattle, who since May 1920 has been sales manager of US Navy Board of Survey Appraisal and Sale 13th District.

It will be recalled that during the height of the war it was planned to build both in England and in this country an immense fleet of fast motor boats especially designed for vigorous deep sea work in connection with running down the dreaded submarines of the enemy. In England they were spoken of as motor launches and afterwards as the British M L's. When the United States entered the war a large number of the vessels were ordered as submarine chasers which were known as the S.C's. There were 450 of the 110 class S.C's built for the United States and France, of which those built at Navy Yard Puget Sound, including No 296, are superior in hull construction due to the Douglas fir planking available here. 

The length overall was 110 feet, extreme guards 15 feet 4-3/4 inches ,draught to bottom of deadwood 5 feet 11 inches, full load displacement 75 tons. The very best workmanship and material was specified and the machinery to drive the triple screws was furnished by three 6-cylinder 220 hp air starting and reversing motors built by Standard Motor Construction Company. It was this class of vessel which was purchased by Brooks Gifford of Pasadena, who is the son of Robert L Gifford president of the Illinois Engineering Company of Chicago, Both Mr Gifford and his wife joined their son in Seattle during September to inspect his vessel and to bid him God speed when he moved out of Lake Union late in the month on his adventurous trip to San Pedro harbor.
