I'm just gonna drop some names as guides coz it's too complex a conundrum to answer properly from my phone
at the beach.
Woolacotts are good but skinny and there's quite a few for sale
at the moment.
Anything built by Mick Orchard is a bulletproof work of art.
Talk to Ashley at the cement works boatyard in Warkworth. He's a brilliant boatbuilder
who knows what's up and what's available.
There's a 44' cruising yacht, maybe a Davidson, that needs lots of work on the handstand at Okahu Bay in Auckland
. You could achieve cat one for under 100k there, all told.
Roberts's are rare around here, but if you find one...
Ganleys are great, but make sure you've got a good one.
I wouldn't go near corten on a steel boat, for reasons too complex for this posting
. Mild steel is the stuff. It'll rust, but it'll take decades longer before the rust goes right through the plate. Also, avoid steel boats that were hot metal sprayed. There's a few around and it makes maintenance
problematic, to say the least.
If I were you, I'd think again about ferrocement. The good ones are some of the toughest boats you'll find and that 100k could potentially see you sailing a concrete mansion. I just bought an ex-trawler made in ferro
which has worked out of Bluff for over 40 years. I'd like to see anything other than steel challenge that history
Good luck and see you on the sea.
