I've raised £500 to Newark sea cadets

Organised by Newark sea cadets
Newark sea cadets is vital to the young people in Newark who not only learn skills and confidence but also to feel part of a team and gives them a direction of ambition.
The cadets are desperate for a new safety boat. So to raise money on Sunday 24th June they are doing a "rowathon" of 44 miles. Which resembles the distance from Dover to Normandy.
Anything you could help with would be amazing. Litrally every penny would help.
