Hi Dan,

Yes, the patch will be about 45mm long in the flat, full thickness part, with the scarf extending at least 35mm (just shy of 1:6) each side, so at least 115mm long overall - a pretty...

I've been a bad boy and pranged my Eureka.
On the Yarra near Ivanhoe there's a small set of rapids that I'd never had the gumption to get up past before. This weekend I got a rush of blood to the...

I set the top of my seats roughly 175mm above the bottom panel, with the underside of the supports just above the chines, and have found it fine.
The only time I've been nervous is paddling solo and...

Hi MIK, I really like your 'theory' posts, and this is a good'un.

I've sometimes wondered about the fascination with 'prismatic coefficient' in boat design, and why it should increase for boats...

Frank Bethwaite's book talks about an almost square mast of 'correct mechanical flexibility' with a 'zero strength leading edge fairing' (balsa with saw cuts) and 'tip turbulators' (square knife...

Hi all - great thread. A plywood question that bugs me: Why are the plies in marine plywood generally the same species / strength all the way through?
MIK mentioned beam theory in plywood...

Hi, MAM.

Yes, that's exactly the way it works - the seats are not equidistant from the ends. The bow seat is further from the bow (leg room for a front paddler) than the rear seat needs to be...

My 5yo daughter and her friends love the Eureka, it's a great boat for kids. She'd have pushed for pink & rainbow too, given the chance.

It's a real shame about Philippe wrapping up the BWB...

Doesn't look like cheating to me... All up a pretty classy looking way of getting around.

I took my Eureka on a paddle down to Dights Falls a couple of weeks ago, and one of those MinnKotas would...

My seat tops are 170mm above the bottom panel, and I have had no problems.
I find that with 2 on board the stability is fine - you really feel the boat firm up. Paddling solo I kneel in the middle...

The National Film Board of Canada has some great archived videos of Bill Mason's (from 'Path of the Paddle'), which go through some of these skills and strokes.

The films are divided into basic &...

Cool concept, cool images, cool interactive format. I think you've made something pretty special.

I reckon! :)

Hi all,

It was a beautiful afternoon today; too good for work. I took my pulse, said "ahh" and decided that a mental health half-day was necessary.

The Eureka was already on the roof racks,...

Mine are the 150mm inside diameter white screw-hatches. Good for getting an arm in to feel for water...
Good idea about the syringe, too. I'll give that a go.

I also used SS screws & sikaflex 291. Bought a whole tube of the goop and used a fraction of it... It's now in the fridge waiting to be confused with something edible:D

I wanted a mechanical...

Hi all,
Dumb question:

Phil Bolger used to talk about a "sea of frozen peas" hydrodynamic theory, where the ideal chined boat shape had a longitudinal curve to the sides identical to the bottom...

Nice find - Today Tonight comes through with the goods!

Eureka* now eligible for: "* as seen on TV"

'fraid so. Wouldn't bet the farm on it. Chalk it up as a 'maybe'?

I did see what looked like a eureka in footage of the evacuation of (I think) the Rosalie shops on about 11-12 January. It was pretty early in the floods' impact on Brisbane suburbs.
The canoe was...

True - there's no point designing boats if nobody hears about / builds them!

Here are some photos of my 'workshop' before moving the boat home to Melbourne - my folk's shed in Wistow - very...

Yes, the black & white hull. It'll have the sprit rig - Philippe is building it on commission for (I think) a Melbourne client. It's hoop pine ply - quite chunky - , I think modified from plans...

Hi Mik!

I've been quietly renting boatbuilding space from a local boatbuilder (Philippe Patacca) for the last couple of months. I think he likes the eureka & GIS so much he's become an agent for...

Hm. Try posting that image again...

Hi All,

This is the Eureka I started at the Duck Flat autumn school in '09.

Here's how she looked on the way home earlier this year (once I'd installed bulkheads, decks, inwhale & gunwhale in...

Ticky-tacky is my favourite building material!

Hi all,

I love Drew Heath's little 'Zigzag House' - a mini-sized version of M.A.M's stacked cube idea, made out of simple-but-nice stuff in a lovely place.
...

Hi All,

SoG sounds like a great concept - a 'feral' and a 'cashmere' kid in the one litter. 12' is a great length - about the size of a sabre (my fave 12'er)- relatively easy to lift, launch and...

Hi all,

Mik, after mythbusting jib slots, you've started on planing!

My imperfect understanding of planing is that the boat stops climbing 'uphill' over the bow wave, climbs on top of the...

Wowowowhoah.... hang on Mik, you're doing my head in...
So a jib doesn't operate by improving the airflow over a mainsail by speeding the air and reducing pressure in the slot - it actually reduces...

Hi all - I need help/advice/reassurance!

We just mounted the roof racks on our car for the first time, and they look mighty close together - 1.2m at the absolute most, maybe less.

I have...

Hi all,
Bjorn Landstrom's 'Sailing Ships' has a nice reconstruction of a 7thC Nordic merchantman based on pictoral stones from Gotland with triangular 'cutwaters' under those beautiful curved...

The 'Trails SA' website might be worth a look if you're interested in canoeing (or hiking, or cycling, or diving or horseriding etc.) in South Australia:...

Very tidy. She looks great.

If you have no luck contacting Lindsay Cunningham: Elwood sailing club sailed Quickcats & Dolphins until fairly recently - If you get in touch with the club you may be able to find someone there with...

Hi Robert,

I like the webbing seats - looks like a solid timber frame - how did you fix the webbing to the frame?

Jack

True... The only real risk on the way home was dodging all those Mallee farmers dancing for joy at the sight of rain!

Jack

I found at the autumn scool that there was a surprising amount of flexibility in the build process - Mik, David and Ted encouraged us to prioritise things that would get us transportable boats by the...

Hi Mike, MIK,
Sounds like the site might be a good candidate for inclusion on the state heritage register, or protection by some sort of local planning overlay as a working example of SA's...
