Earlier this week, allegations surfaced that the late politician would take vulnerable children from the former care home, Haut de la Garenne, to his boat and sexually abuse them.
However, David Arnold, who sailed aboard the yacht, the Morning Cloud, has said that the vessel needed a minimum of three crew and lacked privacy.
He said it was ‘incredible’ that anyone could have done anything sexual on board the boat unless everyone on it was also involved.
In an interview with The Times, Mr Arnold said that it appeared that Sir Edward had little interest in children.
He also noted that the former Prime Minister, who died in 2005, was always shadowed by police officers while on land.
He said: ‘All the time he had his Special Branch.
‘They were always there when he was brought off the boat. That is worth emphasising.
‘He was the one who insisted that the ex-Prime Ministers should be accompanied at all times by two Special Branch people.’
He added: ‘Those are not the actions of a man who wished to carry out clandestine activities.’
The former navigator said that the racing yacht would make a stop-off in Jersey on their return from an annual yacht race from Cowes to Dinard.
He also said that the accommodation on board the racing vessels was relatively basic, and added: ‘They do not have cabins and doors and staterooms and air conditioning and all the things you would enjoy on a big motorboat. There was no privacy at all.
‘It is incredible that anybody could have done anything sexual unless everybody was in on it.’
He added: ‘He did not seem to be very interested in young people.
‘He was very protective of his crew. They got closer to him than an awful lot of people.
‘We would always go everywhere with him. He loved his crew, he had duties as an MP and he had his music.’
On Wednesday, it was reported that the States Police were among seven forces in Britain who were investigating Sir Edward over historical child abuse.
Yesterday, police said that they would not be releasing any further details into their abuse investigation.
The news comes after UK lawyer Alan Collins urged them to release more information to encourage victims to come forward.
The solicitor, who was worked on a number of high-profile child abuse cases, described the police’s move to only name Sir Edward as a ‘feature’ of their investigation as ‘troubling’.
The police declined to comment on the investigation and stressed they were always keen to hear from potential victims.
