Chines vs Round bilge – Is there evidence of superiority?

Traditionally we were all told that chines were draggy, induced vortices and were slow. But in restricted dinghy classes where different hull designs are allowed chines predominate. And now chines are appearing on yachts as well. Sailors seem to be voting with their feet. Is there evidence?

Philippine Boat Builders and Plywood – aesthetic and sophisticated

Slightly arrogant I!I vist the Philippines then Malaysia and also find a large community of Filipino boat builders there. I find they know much more than me about boat design and varieties. Stunning mix of different boats from curvaceous to plywood and boxy.But Gosh … the shapes they come up with!

Tornado - composite NS14 by Malcolm Eggins - composite hull, inlaid plywood deck

Thankyou Malcolm Eggins, designer and builder of sophisticated racing dinghies

Malcolm Eggins, boat builder and designer has passed away.A small tribute to one of the many people that has influenced me and many other sailors and designers. He was a part of the development of Moths, NS14s, VJs, VeeEsses and many other Australian racing dingies as a builder and designer along with his son Darryl. He won several State Championships.

Book – “A lighter ton” – New Zealand racing yacht design in the 1970s

In the late 70s as a sailing teenager I drew boats on every available paper surface.A new book “a lighter ton” describes the exciting development of racing yachts to create newer, lighter, faster and cheaper and FUNNER boats.Many of the developments were from New Zealand designers such as Bruce Farr, Paul Whiting and Laurie Davidson. A new book by Richard Blakey covers this exciting experimental period in yacht design

12sq metre Sharpie (Heavyweight Sharpie) for sail in Australia.

A rare beast, a circa 1960s 12 square metre sharpie with some of the original rig is for sale. I am not involved, but in the interests of helping preserve a little bit of Australian sailing and boat design history I would like to help find it a good home.The 12sq metre (heavyweight) Sharpie came to Australia for the 1956 Olympics. NZ first, Oz second.However the boat totally changed the approach to the design of Australian skiffs. Thought you might be interested to read my understanding of the design issues and influence.How the Sharpie name went from the USA to Europe and then to Australia – and how it changed our boats.

Rules of thumb for boat and yacht design – are they legitimate?

There are lots of tips for building and designing boats on the net.“Rules of thumb” are often quoted to help with the calculation of how much sail or how much keel or centreboard area or how big a mast is allowed to be and many other areas. Can a boat be stretched or shrunk or lengthened?But how correct are they? Are they the best guide?

“All boat design is a compromise” – Rubbish

Reprint of an article I wrote a few years ago for Watercraft magazine in the UK.The article points out why I think most of the discussion about boat design being a “compromise” is rubbish and taking that point of view means that the design is sure to be compromised.What happens if we don’t accept the compromise?

MSD Rowboat in Brisbane. Built by Tom

Tom has built his MSD Rowboat in Brisbane.I met up with him recently and we drove down to the coast towing the rowboat to the river at Nudgee. A bit of wind and a lot of current because of all the rain.Tom has trimmed down the skeg to get the boat to balance nicely in all directions. Before the modification the bow used to blow around – now it behaves nicely.I took quite a few pictures.

Is the OzRacer or Oz Goose a good looking boat? Part 1

A little bit of writing how form in boat design seldom follows function in terms of what “looks good”. It was prompted by a discussion about whether the PDR is good looking or not.My Podcasts on design also cover this idea to a greater depth – they are in the menu at the top of each page.

New article out on PDRacers on Duckworks.

A nice little article by Jackie Monies who is turning into the writer in residence for the PDRacers.It posits the idea that because of its cheapness, ease of building and the creativity in the group that it qualifies as the “All American Boat”.Actually I think it is the perfect boat for places that are water rich and cash poor. Anyone can afford to go sailing in these cool little sailing boats. The options of material and design solutions allow the boats to be built of local material just about anywhere. Very cheaply.

“Disposable” Canoeing – building a canoe in a few hours.

I don’t have a car so how can I go canoe touring? Its something I fell in love with in the USA on Lake Powell.This is an idea for a simple, cheap, almost throwaway (or give away) canoe. I can get the materials shipped to somewhere on a river, build the boat over a couple of days then go for a paddle.At the end I can give the boat away or store it for the next part of the trip.

Podcast Online – Wooden Boat Construction by Michael Storer – 2 of 3

This is the second of my talks in the USA. It focuses a bit more on construction and some of the methods that can be used to keep a boat light and simple, but very strong and stiff.It also discusses how there is a “creep” in boatbuilding and design that increases the weight of boats way over what is really needed for a strong structure.
