How about this Searle?
I think it's been on the market for awhile.

I believe there are several R T Searles boats here in South Australia. The boatyard in Port Adelaide was sadly forced to close in 2009 due to the land being acquired for housing development. You may like to search the RSAYS website as they have historical data on boats that have been moored at the Club over the years since 1869.
