THE Colne Valley Owls are raising cash to support hospital ships.
The hospitals, known as Mercy Ships, offer vital medical aid for developing countries by mainly travelling around the coast of Africa.
The Owls are an over-50s social group for keep-fit enthusiasts and Monday group chairman Brian Farrington chose Mercy Ships as this year's charity.
The aid organisation has three liners staffed by volunteers who also set up field hospitals in villages.
Since the first Mercy Ship set sail in 1978, more than 8,000 operations have taken place on board and more than 200,000 people have been treated on shore at temporary hospitals.
Mr Farrington, Owls chairman for more than 18 years, said: "We had a slide show and talk about the charity, the things they do are amazing and we had not even heard of them before that.
"The biggest vessel has 474 voluntary crew members who give health care, six operating theatres and 78 beds in the hospital.
"They only pay for a crew to sail it. They sail to various countries in the Caribbean, Africa, wherever medical attention is needed. They can even travel inland."
A raffle will take place at the Colne Valley Leisure Centre's Social Evening on December 18. Tickets cost £5 which includes a hot supper, entertainment and dancing.
They can be bought from the Leisure Centre or by calling 01484 222522.
Brian added: "We are trying to raise as much money as we can for them in December. If anyone can donate to the raffle or buy tickets, that would be gratefully received."
