The ex work boat Wakatoa recently popped up on tme, thanks Ian McDonald. She made a brief appearance on WW back in March 2014, link below. At the time she was berth at Thames and it was commented on WW that she had been listed in the CYA Classic Register booklet as being built c.1939 in the Hokianga. https://waitematawoodys.com/2014/03/05/wakatoa/
The tme listing now has her as being built in 1929, and comments that she stated her life towing harbour barges. We now know she is 36’ and powered by a 130hp Isuzu 6BB1 that gives her a 7>8 knot cruising speed.
If you are looking for a nice salty looking double-ender, bidding is sub $10k, so she could be a bargain.
