Mitchell Hutchcraft, Conor Patterson, Jason Gardiner and Oscar Stone will set sail next week from the coast of Gran Canaria travelling across the Atlantic arriving at Barbados.
The boys will be rowing 12 hours each day, every day for six weeks straight burning 5000 calories each per day. They will be living almost completely on military ration packs for the entire journey.
The trip will be totally unassisted with the military men receiving no help from the outside world.
Mitchell Hutchcraft, originally from Ramsey, said "Myself and two others are former royal marine commandos and we have served several years in the Royal marines, our aim is to raise money for a great cause
"We are also raising money through other means, this includes organising fundraising events and seeking corporate sponsorship. This is where we are aiming to raise most of our funds"
He continued on to say: "As a four man team we will row in shifts with two people rowing at a time, with two hours on the oars followed by two hours rest allowing us to row 24/7"
This incredible feat will be accomplished almost entirely through crowd funding and all profits made will be directly sent to the Royal Marines charity.
