Task: Question Answering
Input (English): Passage: Robert Rainbird, proprietor of the Greatwood guest house at Mylor Creek, near Falmouth, was familiar with Darlwyne, having cruised with Bown in one of the earlier Tall Ships sailings. According to his later account, when two of his guests asked him about the possibility of organising a sea excursion, he put them in touch with Bown. On the evening of Saturday 30 July, amid celebrations following England's victory in the 1966 FIFA World Cup Final, Bown and his friend Jeffrey Stock, a qualified engineer, visited Greatwood. They found that enthusiasm for a sea trip had spread to many of the guests, and an agreement was made to take a large party to Fowey the following day. Different accounts were given later of the financial basis for the proposed hire – whether it was to be a fixed charge or a rate per head is uncertain.Barratt, the boat's legal owner, professed ignorance of the arrangements made at Greatwood, believing, he said, that Bown had gone there to discuss with Rainbird future charter work once the necessary licences had been obtained. Under local regulations, a licence for carrying up to 12 passengers was subject to examination of the boat by the harbourmaster, who would also require the person in charge to be a licensed skipper. Vessels proposing to carry more than 12 passengers needed a licensed master, a qualified marine engineer, and a Class III Passenger Certificate from the Board of Trade. This certificate was only granted to vessels in good condition with watertight hull compartments, a two-way radio, a qualified radio operator and a range of safety devices. Darlwyne had no radio, no distress flares, and carried only two lifebelts. Bown had apparently begun enquiries with the Falmouth Harbour Commission, but neither he nor Darlwyne possessed any of the licences needed for the boat to operate commercially. 
Question: What is the last name of the person who, along with Darlwyne, did not possess any of the licenses needed to operate a boat commercially?
Output (English): Bown.
