As swaps, the cache initially contained some packs of balloon waterbombs. It was only after hiding it that I thought of their potential environmental impact. If you swap and take some please bring them home or, if you use them on the islands, please pick up their remains. Thanks.
The cache is not at the posted coordinates. It is at N 49 5?.??5 W 006 ??.?58
If the puzzle generates either a 0 or 10, treat both as a 0.
In keeping with the puzzles's theme, the cache is hidden close to a gig shed. You can find its location by solving the puzzle but, if you have detailed local knowledge, you might be able to bypass the encoding and make your way straight there. Looking at the gig shed door, the cache is below and on the left. Note that the spoiler photo is not showing a wall so please don't demolish any near to the Porthmellon gig sheds (they may not be the right ones anyway).
Pilot gigs have a long and venerable history. Originally, they were used to place pilots on board ships passing the Isles of Scilly on their way to the mainland. Gigs would race out in order to be first and get their share of the pilotage fee. Gigs were also used in the days before the RNLI to attempt rescues from wrecked ships. More recently, gig racing became a Cornish and Scillonian sport and 1990 saw the first world championships.
The world championships, now with well over 100 gigs, are held on the Scillies during each May bank holiday. Scillonian gigs race every summer Friday night for men and Wednesdays for women.
The dates of construction of the gigs vary a great deal. Some, such as Shah and Campernell, were working gigs in the 19th century. Others, such as Emma Louise, have been specially built in recent years for sport racing.
The gigs have a wide variety of names. Many, such as Nornour, refer to locations; others, such as Alfie Jenkins, to people.
Recently, we heard about two special races.
St Mary's quay to the Old Wreck Buoy.
1st Alfie Jenkins (Tresco & Bryher)
2nd Emperor (Tresco & Bryher)
3rd Bonnet (St Mary's)
St Mary's quay to Tresco.
1st Cadmus (Salcombe Estuary)
2nd Senara (Zennor)
3rd Majestic (KNZRV, Muiden)
