Most
of the items below have been my responses to various debates on
the PDRacer.com forum. I
have placed them here for easier
access.
For general information about detailed OZ Racer Plans and construction
click OZ Racer Website - Formerly OZ PDRacer website.
Disclaimer
- Our idea has been specifically -
to develop an easily
built version
of the PDR
with excellent performance
without excessive expense.
Also see the EPOXY and Boatbuilding FAQ for tips on building,
repair, methods etc
OZ Racer FAQ - applies to early PDRacer Development
This section is largely a historical document but many of the items are instructional for all boat design.
As we all know the OZ Racer
started off being part of the PDRacer movement. So the below are
all historical documents referring to PDRacers and our OZ versions at
the time. Readers are to be aware that now the OZ Racer and the
PDRacer have headed in different directions with no official links,
though we have many lasting friendships from our involvement.
The
reasons for the OZ PD Racer
Rules - boats to be cheap and equal
Making
Carbon Fibre Components
and comparison with wood.
Why
exotic second hand parts of other boats cant be used on OZ PD Racers
Hull
Structure
How
light can a PDR Racer be built of wood? 10kg/25lbs?
The Weight
limits on the OZ PD Racer - approx 28kg/60lbs
The Death of
Small Boat Sailing in Australia. TOO EXPENSIVE.
Questions
on whether the OZ PD Racer will distort under sailing loads and
suggestions about sending me on a diet
Plywood
The
correct plywood thicknesses for a robust boat
Peter
on how much
resistance to puncture does ply really need to have
Centerboards and Leeboards
Leeboards vs
Centreboards
Why
the centreboard position in scows is different from pointy bowed boats
and why it ended up not making a difference to the OZ PD Racer
Are there
shallow draft options for the PD Racer - my local waters are tres
shallow
Which is better -
a swinging centreboard, daggerboard or a leeboard?
NACA Foils and the
performance
advantages
Hull Design
Discussion
about the extreme aft location of the OZ PD Racer centrecase
Safety
Capsize
and Recovery in OZ PD Racers
Why we don't use
mainsheet cleats and design for capsize and economy.
