I have copied this post from Chagos news in our SE ASIA forum to illustrate what can be done by cruising yachtsmen/women when the chips are really down.
17th September 2007 message relayed on the radio net for S.E. Asia by the Catamaran "Backchat" on its way back to Malaysia from Male in the Maldives :-
At Chagos, an South African boat "Shoestring" ended on the rocks at Takamaka atoll after a front came through. Smashed rudder, bent drive, and holed, plus other damage. The hole was plugged with epoxy putty and the boat then beached at Boddum atoll. Rudder replaced with old centreboard, hole ground out and glassed, and rest repaired except for drive. Prop cut off and shaft not sure. They are now ready and will be leaving for Africa in the next couple of days. The Tsunami was a non event there. In 2004 it was only 2 1/2 feet but was very noticeable so this time it was obviously zilch.
All the Best
Jock on Backchat"
The above message regarding Tsunami at Chagos confirmed by other cruisers now in Chagos.
In case readers are not aware of the location of the Chagos Archipelago :-
Almost slap bang in the middle of the Indian Ocean - with no facilities of any kind whatsoever
on the 2 atolls where cruising yachts are permitted. Only Yachtie ingenuity to depend on
(don't leave home without your epoxy putty!)
