[MHml] Advice please

[Rob Denney]

G'day,

You are in the boatbuilding capital of the world.  Buy a carton of beer and
drop into any one off boat builder on Friday afternoon and you will get more
state of the art information than you find in any book.  Then call ATL in
Henderson and they will sell you what you need and supply as much technical
info as you need.  Buy some sample bits, do a bit of practise and you will
be ready to start on the boat.

To find the one off builders, attend a club meeting of the NZ Multihull
Yacht Club.

regards,

Rob
