McLennan said he has experienced homelessness, and hopes the boat also can give hope to people who are struggling.

“You can create a home; you can create something that is valuable and that’s what I’ve done here.”

A second attempt at setting sail

He plans to sail to St Helens, on the north-east top of Tasmania, where he hopes his yacht can be re-assessed and secure full registration to enable a Bass Strait crossing.

“I want to see that thing go under the Sydney Harbour Bridge and people go, ‘Ooh, wow’.”
