Had an opportunity to check out a Walker H28 in Cairns. In a strange mod the engine has been replaced by an electric motor. Did not see a huge battery bank, looked like maybe 400 AH setup, but it had a sophisticated charging system for mains (read marina) charging.
The heads area also looks like it was set up to form a 3/4 bunk on the Stbd side.
Access hatches in the cockpit sole make for easy access to the motor. (And to re-fit a diesel).
Apparently been on the market for a while. Has rusty gal standing rigging. i am told that riggers in Cairns are a lot cheaper than down South.
Also told that shipping to Sydney could be as little as $8,000. Compare with shipping from Dampier, which was $18k.
