The dramatic experiences of wildlife enthusiasts aboard Captain Keith Leeves’ Free Spirit “seafaris” will continue to be of a natural, not mechanical kind thanks to a complete overhaul by experts from Mylor Yacht Harbour’s Marine Team.

With hundreds of passengers venturing forth from Falmouth with Captain Keith each year to spot dolphins, seals, basking sharks and even whales, the reliability and safety of his Aquabell 33 Sports Cruiser boat is imperative.

“I entrusted Mylor’s Marine Team with this crucial work because they have the world-class skills and the ability to do a brilliant job speedily enough to get me, and my clients, back on the water so we don’t miss out on any of those great sights,” he said.

The Marine Team’s complete engine overhaul involved stripping down Free Spirit’s trusty Perkins diesel to the last nut and bolt and surveying every component. The crankshaft, pistons and rings were replaced, the cylinder bores honed and polished, and the fuel injection pump re-calibrated. Finally, it was rebuilt - with a few clever modifications to the exhaust system so it runs more quietly.

Keith was so impressed with the work he brought Free Spirit back to Mylor to have decking replaced and her sun-bleached blue topsides sanded and buffed to an "as new" shine.

"They've done a marvellous job,” said Keith. “It's like I’ve got a brand new engine. I really can't commend Mylor enough, the whole team from the reception to the workshops. They have been so accommodating and they’re always available if I have any queries – it’s a terrific service all round."

The upshot is that passengers aboard the Free Spirit this spring have already spotted a rare humpback whale, pods of common dolphins, basking sharks, puffins and choughs. Captain Keith pioneered specialist wildlife-spotting cruises in Cornwall back in 2002, combining tourism with conservation data-collection. Since 2012 he has run AK Wildlife Cruises from the flybridge of Free Spirit.
