What this video covers
Sven Yrvind modifies a small cruiser to become amphibious by adding a wheel system that weighs a total of 3.5 kilograms.▶ 0:59 The assembly consists of an 864-gram axis and 1.7-kilogram wheels, with weight savings achieved by drilling a 25-millimeter hole in the keel.▶ 0:20 This modification allows the boat to be hauled onto ramps for maintenance, such as bottom painting, or to be moved ashore in locations lacking docks.▶ 2:06 Yrvind notes the utility of this system for past voyages to the Falkland Islands, Baltimore in Ireland, and Porto Santo.▶ 1:49 To prevent loss during installation, he attaches retrieval strings to the wheels and deck hatches, ensuring they do not sink if dropped into deep water.▶ 3:08 With the amphibious conversion nearing completion, the remaining tasks on his project list include installing solar panels and finalizing the hatch attachments.▶ 3:02
