"We know this programme works to help children, our recent survey backs that up," said chairman Mike Daniel.
"We need more donors to be involved so we can provide more voyages for children."
Mr Daniel has recently implemented a new programme that will allow potential donors to "sponsor a child" so donors can see the direct benefit their donation has had.
Someone who greatly benefited from the sail training programme was Ashley Kemp, who went on a youth voyage when she was 13 and has taken part in other voyages for five years.
Her mother Leanne Kemp said: "She was always a shy, quiet person and was nervous about meeting new people.
"But after her first voyage I could definitely notice that she had a lot more confidence.
"Now she will try anything, she is not afraid of things and she has a real passion for conservation and adventure."
A recent survey by the trust of 40 students who took part in the programme revealed 75 per cent felt their confidence had risen and important life skills had been gained from the sail training experience.
