At dawn we were in Prince's Charlotte Bay heading north again. The coast 10 miles away at the hills low & dim. The McElwraith Range, behind which lies Coen, was wreathed in cloud. To the north the southernmost peaks of the Lockhart Mission coast range - 1000-1600 feet stood out on the distant horizon. Passed the Lockhart about 8 o'clock & started across Lloyd's Bay, at the inner end of which lies Portland Roads. In the night the sea gulli chippy as we rounded Cape Brenville. Mon. Apr. 19. Farfrom shore. Low hills + distant sand dunes. Engine trouble. Crossed Sheldrake Bay mostly under sail. In mid-p.m. reached Hamilton Island. Bent anchor for 2 hours while engine repairs. Tide was low. On from the reef the shore partly bare. A core of sedimented coral rock. Vegetation: Cedraria, Conodendrus per-capace, a fig, a patch of small tree toshubs, some sedges, Portunia, etc. Two turtle nests with eggs found. Plan to save some of each for Heateven. Got quite a few souvenir shells. Still 80 miles to go. Tues. Apr. 20. A rough, chippy night with a few showers - strong south-east. Left Hamilton Island about 6 p.m. Start light & anchor chain & let left ship drift on rising tide. Had to start engine to go back & pick up lost boat load of oil cans. In early a.m. had school of porpoises (Lagenorhynchus?) under our bows. They were tricolour brown, gray-white (see opp. pop). The spinula was circular. Pictorial fins scimitar- like. Difficult to see how speed maintained. Weather this nautical was moved much. An occasional anguilliform whirl was only sign of propulsive effort. 2. Dawn soon after we had cross through Albany strait. At 6.30 we passed Cape York. Sands & mist again. Mistily low island to W. and N.W. SW Coasts by 7.30 a.m. Tip mostly bare as in "frost". Another run-out of fuel but soon wetter.
