Sailing in Shark Infested Waters

I don't normally do this kind of thing but my brother has roped me into it so to speak. Later this year I will be sailing a hand built raft around the Indian Ocean for 10 days to raise money for Cool Earth (a rainforest preservation charity). We are looking to raise ￡2000 and I would be very grateful to anyone who knows me and wants to show their support by donating a small amount on our fundraising page.
