JonathanR writes "Two Australian kayakers have departed Sydney on their journey across the Tasman Sea, paddling a high-tech composite double kayak, kitted out with a myriad of telecoms and safety gear. The 2200km (1370 mile) journey is expected to take some forty to fifty days. When they arrive in Auckland, their crossing will hit the record books as the first kayak to cross the Tasman Sea and the longest unassisted two man trans-oceanic kayak journey, amongst other record permutations. The detailed planning and safety preparations, not to mention the kayak design and construction, have been completed over the last five years. An audacious adventure in anybody's book."
