The ideal flat bottomed boat

Duckpunt!

Excellent use for old oppi sails!

There is a whole world of sailing out there, isn't there, that even the cvrda only scratch the surface of.

Well, I would suggest a canoe of course....

Although, I do really like the duck punts too.

But if you are looking for an easy and fun boat to make, look no further than these:

The american 16/30 rule canoe: 16ft long by 30in wide.

or search for '16 30 sailing canoe' on google.

I have really thought about making one of these and there are some interesting threads about them on Sailing Anarchy.

Go on....you know you want to.

Nice (very nice, actually), but not looking for a planker - I've finally admitted to myself that I like to be "in" boats, not outside them, when helming. Just a coward, I guess!

Wood ! I totally agree regarding wood being beautiful, I saw a wooden Flying Fifteen that was ? incredible, But it is rotting as you look at it, you cant stop it, it is inevitable, I agree it is easier to build with wood, but if the Mogo was to be put into production it will not sell in any number made from wood.
Rupert, what about a base made similar to an hollow door, 2 layers of ply stiffened with an honeycomb structure, this would provide stiffness and bouyancy, you then add rest of hull however you want it without worry of providing bouyancy.

With wood, it depends on the quality and how you look after it. Just been in my workshop, couldn't see any sign of my 1937 sailing canoe rotting away, all original planks. I've worked on 50/70/100+ year old wooden boats. planks can be replaced, damage repaired a lot easier than those made from Plastic Snot. There's nothing inevitable about wooden boats rotting, it's all about care and maintenance.

Most of the rot problems on here are in GRP boats, especially those from the '70s where ply is bonded into a sealed tank where it delaminates.

I have scrapped 20 year old GRP boats suffering from osmosis and delamination, and the buggers don't burn when you want to get rid off them (well, they do but the neighbours get a bit tetchy).

Anyway....the ideal flat bottomed boat, has to be the Norfolk Punt. Or if you want a Scow, how about the beast of the YW Scow?

Hi Neil, what is osmosis in GRP ? I know what it is in brickwork and other porous materials.

[neil]

This (short) guide by Nigel Clegg on Osmosis is worth a read. (His book on boat painting is also quite good).

What about:

A PD racer....

Hi Ed
I like the Zipper Scow looks like big fireball and designed a long time before it. The Slipper 20ft with spring boards (sliding seat looks to be a wright laugh if you left the lead off the keel. If Ihad the time money and skill would love to have built one of these boats as I think they could be lots of fun.

the mogo wasn't a modern boat; it was an old hull I picked up on ebay and revamped and rerigged with a BM rig. I never found out what it was originally.

[trebor]

Hi Nessa, I misconstrued Y&Y topic, I thought you were trialling a new design of boat to go into production (for a company),(I did not realise it was your project boat) reading it back now I feel I owe you an apology. Rob.

I am getting to quite like the idea of building a Puddle Duck Racer myself

Some are pretty horrible, but how about this one:

Ed what are you on? It still looks horrible!

[Ed]

he he

ps I guess this would be a bit close to a Minisail:

Ed what are you on? It still looks horrible!

Preeecisely! Just really nasty things...
the home build wooden boat design I've seen which I really admired was John Spencer's Firebug. He managed to get a reasonable looking and sweet hull shape with:-
Constant chine angle, flat bottom, much symmettry even fore and aft. See http://www.firebug.co.nz/design.html
It might be interesting to scale one up a bit for an adult boat, although IME dinghies rarely scale well.
