I'm in the unique position to be able to offer information on both these yachts. I have a full set of plans for both. They were designed in Australia in the late 60's by Dennis knight. If you own one of these yachts or want information just send me a private message.

The second pic shows a lot prettier line to the yacht (deck sheer and cabin trunk).

Does the design allow for a fin keel version??

I am causing a stir on other forums by posting this info' & offering the plans for sale. So please read the following post's... --------------------------------------------------------------------------------------------------------------------------------------------------------------------------***Vessel Hull Design Protection Act, expires after 10 years. Registration must be applied for and approved . Designs which are covered by a design patent are not eligible for VHDPA registration. Covers the shape and the hull and deck if they are sufficiently unique. Protection is afforded only to vessel hull designs embodied in actual vessel hulls that are publicly exhibited, publicly distributed, or offered for sale or sold to the public on or after October 28, 1998.? Does not apply to designs which have not been built and application for registration has to be made within two years of the first public showing of the hull. Once the 10 year term expires the design is in the public domain.

Copyright, term varies and for works created before 1978. and without copyright notice and/or registration there may be no copyright. Works created after 1977 do not require registration or notice. Terms for works which qualify for copyright are very long. In general copyright applies to ?original works of authorship?. Artwork is covered by copyright to the extent it is non-functional. Functional objects are not covered by copyright. Boat plans which are original may be covered by copyright and can?t be reproduced without the permission of the copyright owner (other than within the fair use exemption). However the knowledge in the plans isn?t covered so boats can be built from copyright plans without infringing on the copyright.
-----------------------------------------------------------------------------------------------------------------------------------------------*Common questions about finding copyright owners
What if the copyright owner is dead or has gone out of business?*
If copyright was owned by an individual who has died, copyright is usually passed onto that
personʼs spouse or children. You may be able to check who inherited copyright if you can get a
copy of the personʼs will. If copyright has not been bequeathed specifically, it is presumed to form
part of the residual estate. In Australia, contact the Probate Division of the Supreme Court in the
State or Territory where the author died. Alternatively, if the work has been published, contact the
relevant publisher.
If a work has not been published, the person to whom the manuscript is bequeathed is also
understood to inherit the copyright in that work unless the testator has indicated otherwise.
If copyright was owned by an Australian company which has gone out of business, you may be
able to get information about what happened to the companyʼs assets (which include copyrights)
from the Australian Securities and Investments Commission (ASIC): www.asic.gov.au
*What if I cannot find the copyright owner?*
The Copyright Act does not allow you to use protected material without permission merely because
you are unable to find the copyright owner.
Nonetheless, in some cases, publishers and other users make a commercial decision to use
copyright material despite having failed to find the copyright owner. They weigh the risks of a
copyright owner bringing an infringement action against the benefits of reproducing the work. They
sometimes include a statement (referred to as a ?good faith notice?) saying they tried to find the
copyright owner, and that they are willing to pay the copyright owner a reasonable fee. A good
faith notice does not give legal protection from being sued for infringement.
However, on a practical level, it may show the copyright owner that the failure to obtain permission
was because the user could not find him or her, not because they wanted to avoid paying for the
use. Copyright owners may settle a claim, by accepting an agreed licence fee, in these
circumstances.
If you intend to use such a notice, it is important to keep records of all attempts you have made to
locate and contact the copyright owner.
*What if I do not get a response from the copyright owner? Can I go ahead and use the
material?*
The Copyright Act does not allow you to use material without permission if you have not received a
response from the copyright owner. You may decide to make a commercial decision to go ahead
with your intended use but, in doing this you run the risk of being held liable for copyright
infringement if the copyright owner brings an action against you.
------------------------------------------------------------------------------------------------------------------------------------------------So to sum up, I have spent over 2 years searching for information on Dennis & his designs, his family & his estate. I have searched the data bases of IP AUSTRALIA, AUSPAT, ATMOSS & ADDS. So far I havn't found any information on patents for the designs or the copyright holder/owner. I am currently pursuing contact with the Aus' copyright council & supreme court probate divisions in the relevant states. All search efforts have been recorded. I pass the design info' on with full credit given to the designer & any royalties due would gladly be passed on to the copyright owner or the estate, whichever is relevant, should contact be made. Although these designs are from the 60's the information used to build them can be employed today, with respect to more modern materials and/or build methods. I am offering copies of these plans for sale at a reasonable cost & current owners of these yachts will receive copies for as little as the cost of copies & associated postage (Australia only). Copies can also be given to current owners via electronic means for FREE. (Australia only) . Contact Dirk, djyello77@hotmail.com
