The former Royal Scots Dragoon Guard, 82, has raised tens of thousands of pound for his numerous charitable exploits in his home-made boats the Tintanic and Tintanic II.
He has today announced his latest adventure set to begin later this month to raise money for Chichester-based Children On The Edge which is supporting Ukrainian refugees.
Launching on Friday, April 29 from Chichester Yacht Club in Birdham, the West Wittering resident will undertake a number of nautical expeditions including the Beaulieu River, Bucklers Hard, the Medina River in the Isle of Wight, and The Serpentine in Hyde Park.
Major Mick said: "This year I will be looking for a 'salty Adventure' which will be a little more 'edgy' than in the past. I have organised for the launch, the Chichester 'Town Crier' and also the 'Georgia Ramblers' who will be playing to add a bit of fun to the occasion.
"Members of the public are welcome to attend. To add a little colour I will be wearing my Union Jack suit as it is Jubilee year."
He received national attention with his previous adventures, rowing 100-miles along Chichester Canal and then another 100-miles in famous waterways across the country.
