On a related note, it it selfish that whenever amatuer sailors do sponsored sails, they are raising money for the very organisation that will rescue themselves.
Seems a bit self serving...
The ones I have seen are often mostly getting donations from fellow sailors or people who live close to the sea anyway
and tourists - but whatever
As far as Three Peaks is concerned - I would be more inclined to donate to the ones that sail and walk
basically they start in Caernarfon and the walkers walk up Snowdon and back - i.e. from sea level
then when they are back it has to be timed for the boat to sail up the Menai Straits - which is tidal and very fast running
The walkers rest/sleep/recover while they sail up to the Lake District and then the walkers walk - again from sea level - up Scafell Pike
and back
then sail up to Scotland - not sure of the location
and the walker go up Ben Nevis and back
clock stops when they get back on board
That seems like a real challenge!!!
