Double-ended 10ft clinker-built skiff
A very sweet but difficult looking clinker boatbuilding project. If anyone builds this one, I've love to hear about it please!

Practical Boatbuilding for Amateurs
Classic 1889 boatbuilding book by Neison and Dixon Kemp.

Cinderella

Blackfly
Free designs for a very sweet ply camp-cruiser for one, or a cat-rigged sailing dinghy for more.

intheboatshed.net - a blog about old boats
Not really about free boat designs - though there might be some later - but a new blog about boat restoratons, traditional boatbuilding, and traditionally-derived boats. Most are in the UK, but we will include some US material, not least because the author is an enthusiast for American boat types. Please visit!!!

Bean boat canoe
A little open-canoe for paddle-savvy kids who love the water, and aren't nervous in a tippy boat!

Classic outboard launch
I like this one from an old American magazine - built with some of the right period details, it could be a real head-turner.

Sharpie plans
Plans for a 12 Square Metre Sharpie - one of the more obvious European developments from the North American sharpie working boats.

Tubby dory
A slightly tubby-looking dory based on an old boat adapted for sailing as well as rowing. Again, I think it must have been copied from an old American magazine.

Kayaks, paddles etc
Still more on canoes. Why has the world gone canoe mad? Because they're a good thing, that's why...

Proa
Proa by Othmar Karschulin. Be proa-active, why don't you?

Optimist plans
Plans for building an Optimist. I don't know if they'd be accepted by the Optimist mafia these days though...

Hulls to AutoCAD
Here's how to successfully transfer 3D files from the Carlson Chine Hull Developer into AutoCAD.

Stability essay
Our friend Hannu again, this time on the subject of stability.

The remarkable inventions of William Watt
Inventive individualist William Watt has some very interesting pages that small boat design enthusiasts should see.

Which glue do you trust?
Here's something to make you think hard about which glues you use...

Free designs
If you don't mind dimensioning these drawings for yourself, some of them are free. I must say that the sailing boats drawn with their transoms in the water look very odd to me, but some of the others look pretty good.

Free CAD
Alternative free CAD package

Powerboat plans
Some free old fashioned powerboat plans here.

Sailcalc
Peter Vanderwaart's excellent labour-saving sail calculator has been getting better and better.

Hydrofoil primer
Learn about hydrofoils.

Two-sheet skiff, and electric power skiff
They're a bit too light on design displacement to my mind, but certainly worth a look.

Polycad and Yachtlines
I'm reminded that Marcus Bole's Polycad site offers some real treasures and not a few challenges for amateur boat designers, including Polycad itself and Yachtlines, which I'm told is very cool indeed - apparently you punch in a few hull parameters and out pops a workable hull. That's a scary thought...

Hullform updated
I gather Blue Peter's free software has moved on from the DOS version many of us tried a few years ago and is now available in Windows and Intel-based Linux version.

New Micro Mouse variant
I would never have guessed that there would be so many variations on the Mouse design - but I would also never have guessed that so many of these little boats would be built, and we're now up to 112 amazing launchings. This latest Mouse variant is designed specifically for younger children, and has a flat bottom for easy building. I've found that kids can cut timber and hammer nails into predrilled holes under close supervision, though I'd advise parents to keep them away from adhesives. Also, Micro Mouse has a big sister Flattie Mouse
that combines the looks of the curved sides of the standard Mouse (laughter off) with the ease of flat-bottomed building. Yes, I know it's called Mini Mouse in the file, but we're going to change that.

Tiny punt
My good friend Les Brown's 5-minute punt design. Even if you don't want to build a punt, I'm sure it'll make you smile...

Dark Ages boats
British boats of the Dark Ages.

Hjortspring Boat
An ancient and rather fabulous canoe found in a peat bog in Denmark.

Cedar strip dinghy
Lines for a very nice small dinghy from cedar strip.

More Russian plans
More Russian stuff - I hope some of you can read it better than I can.

Hulls to AutoCAD
Rick Malagodi's method for persuading Chine Hull Developer (aka Hulls) .dxf output files to work in three dimensions under AutoCAD.

Alternative small boat
Here's Thorbjorn Lee's radical approach to the one-sheet boat. Unconventional it may be, but T's pleased with its performance, and I think it's a very interesting idea.

Tiny punt
My good friend Les Brown's 5-minute punt design. Even if you don't want to build a punt, it should make you smile...

Hot Rat
Dig this - a 12 by 3ft flat-bottomed, flat-sheered Mouse derivative designed to be built in a weekend. With a 70sqft leg of mutton sail, it should give an adult or older teenager a fun wet ride. What could be better for the summer? And this could be the cheapest, simplest club DIY club racer seen since the Optimist.

14ft Expedition Mouse
Some call this a Mouse for grownups: I call it the Expedition Mouse, for it can be paddled, sailed and even slept in with the help of an airbed. I think it's novel and interesting compromise for the adventurous paddler, and it's still a very simple building job.

Gavin Atkin designs Yahoo group
A Yahoo group for people building and using my non-Mouse series designs. Join the race to be an early member ;-)

Scale explained
A teach-in describing some ot the mysteries of scale.

Fun with jonboats

Instructions for designing and making your own jonboat.

Is this the ultimate one sheet boat?
The man behind these pages makes quite a large claim, but whether or not he's right the use of materials and the discussion are both well worth reading, particularly if you have ever tinkered with the one-sheet skiff idea.

Carene update
Carene's promoters have decided that Carene50 should be withdrawn so if you have it bookmarked you may now find your link to it dead. However, they have decided to offer a free download of Carene 2002uk, which will allow the user to create a hull with two chines in a similar way to Carene 50 and will allow saving and printing of designs and export to dxf files . If you want to create a hull with three chines or to use the multi plank setting (up to 20 planks evenly spaced) for round bilge hulls with the additional feature of auto-calculation and output of plank overlaps for clinker construction, you will need to purchase the licence. http://www.alaska.net/~fritzf/Boats/Wacky_Lassie/Wacky_Lassie.htm

Wacky Lassie
I found myself thinking about the Wacky Lassie easy to build flat-bottom canoe the other day - and even though I think I've linked to it before, because it's a great little boat I thought I should put up this link again just to remind you all.

Gidge Gandy's Groovin Garvey
This is Sandspur - a great little garvey design from The Rudder. Once again, we have Craig O'Donnell to thank.

A fat little skiff
The building of a fat little skiff, with plans.

Polycad
Fascinating hull design software.

Standard sail dimensions
John Kohnen - the man behind The Mother of all Maritime Links pages, etc - has begun assembling a catalogue of the dimensions of the sails designed for standard boats. His very reasonable theory is that second-hand standard commercial sails are the cheapest available, and that they should be used more often in home-built designs.

An index to the Ideal series
Also from John Kohnen is this tantalising index... Thanks to Jeff Gilbert for pointing these pages out to me.

Low-cost boat building with Polysails
Dave Grey, the man behind Polysails, has begun a project to provide more low-cost boat building material aimed at families and teenagers, and plans more. While you're there, do take a look at his articles about making sails.

A hull design wizard - really!
This is an astonishing piece of work - a software wizard that asks a series of reasonable questions and in return spits out a Carlson Chine Hull Developer model of a proposed chine hull based on the recommended ratios and proportions spelt out by some of the best small boat design books I know of. Hulwiz's files should be regarded as a starting point, not as a finished product, and it is possible to create silly or even dangerous results by giving it silly inputs. Nevertheless, I think Lew's contribution in developing this piece of software has been terrific, not least because of the huge range of hull types it offers, including prams, double-enders, sharpies, dories, vee-bottoms and the rest. If you decided to play with it - and you should as it's a real treat - you'll be pleased to know that the latest version of Chine Hull Developer is available near the bottom of Gregg Carlson's home page.

Mouse boats go open-source
Here's a radical idea - the Yahoo group mouseboats is now open-source. Anyone can design a Mouse-series boat and it will be included in the collection of designs if the ruling tribunal accepts that it embodies the spirit and features of a Mouse-derived boat. To be accepted, designs must also come with a good amount of design information sufficient for another amateur designer to adapt move the idea on in some way. Already there are a good range of free designs for small one-, two- and three-sheet Mouse-derived boats and I know there are more to come. I think this represents possibly the best opportunity to play with small boats the world has ever seen...

More magazine plans
I have linked to these pages of plans scanned from 'Science & Mechanics' and 'Boatbuilder Handbook' before - but the collection has grown so quickly I feel I should draw attention to them again. The designs include hydroplanes, runabouts, sailing craft of various types and sizes, cabin cruisers ranging from 15 to 21ft, a 25ft houseboat, and, tucked away in a section called 'Other excellent boat plans' two tunnel hull racers, a 'Sea Doo' and a canvas kayak. My favourites are the 8ft outboard runabout for kids, the 12ft JonBoat, and the 16ft dayboat and pocket sailing cruiser.

Still more magazine plans
The Polysails site also offers a range of interesting old magazine plans. Just recently I noticed a lively 18ft sloop I hadn't seen before - Corky.

Christopher Warner's undertaking commissions at what I believe are very attractive prices. Yes - I've broken my rule here and included something that's not free design information, but Chris is a talented chap offering something some of us will find useful.

Singlehander, sailboard attitude
Is this the ultimate Mouse series boat? Maybe! It's traditional to thumbs down narrow sailing craft, but the thumbs up sailing canoes - and that's one tradition that makes little sense to me. Still, if this is to be a sailing canoe, so be it. It should be lively and fun, and challenging to sail with its 63sqft sail (there's a polytarp-style sail cutting diagram) and optional wings for youngsters. The boat is just under 12ft long from three sheets of 1/4in and a quarter sheet of 1/2in ply. There's also a smaller alternative sail for those who prefer to stay out of the water. Until it's been built and proven on the water, it's certainly best to regard TheEdge as an experiment... But it might be just the right experiment for this summer. PS - if you can't print it at a size where you can read all the information, you could take the files to a print shop.
