Gavin Mair Marine Design
Gavin was the original external contributor of advice to the Hullform project. After
Blue Peter Marine Systems, he's the world expert on Hullform. He turns out some
not-half-bad designs, too.
Michael Storer Boat Design
Wooden Boat Plans, Designs and Modifications - Michael has been using Hullform since
the MS-DOS days of the early 1990's.
Cemberci Denizcilik
Another user since the early days - 1990. The
main site is in Turkish, but they have
provided a page of sample designs with English translations.
Hawaii Marine Company (Brian Trenhaile)
Brian first purchased Hullform 5 back in 1991, so he's no rookie either.
The Yacht Design Company (David White) (located in the UK)
David is the user who has worked Hullform 7G/8E the hardest - and makes life hardest for
support@hullform.com too (no complaints - many of his inputs are reflected in version 8).

Kendrick Design
Ray Kendrick offers a wide range of designs, particularly multihulls.
Ian Smith's Yacht Research Web Site
A goldmine of interesting yacht research items and links.
