But look at this if you've done 56 posts on this forum & built well over 50 boats,& I've 35 posts & done about a dozen boats,what size armada must Richard have built with over 4,500 posts?The man's a legend!

Al.

You don't know the worst of it, Midge and I are in competition to see who can take the longest to build a Storer boat ... apparently

Richard
the dog thinks I'm a legend, even if you lot don't

Ross

Will I be using 6mm ply for the whole project? how many sheets you think it will take with the expansion? The place that sells the marine ply is down to the last few sheets, picked up 5 sheets this week end but want to know how many more I'll need before he runs out.

I assume that the package is in the snail mail system by now. Can't wait to start working on it.
Cheers

Richard,

If he's a boat dog,then I trust his judgement!

My comment was a compliment.

If you can't find an elastic garter,ask Ross to send one down....he uses them all the time when designing boats...he's let a trade secret out of the bag I feel!

Al.

Magd,

I've included a suggested nesting diagram on the expansion sheet. Read this at the same time as looking at the nesting sheet for the standard boat.

My belief is that whereas the standard boat uses 4 sheets in total (plus some scrap for the transom which won't quite fit onto the very tight nesting arrangement), the longer boat will come out of five sheets, with possibly enough left over for the transom as well. You will get one bottom panel and both topside panels out of two full sheets and a three foot part sheet, and the remaining bottom panel and all of the bulkheads, thwarts and tank tops out of another two -and-a-bit sheets.

Al, regarding the use of elastic garters, you should see my research-and-development program...

Boat designers have all the fun!

Now for some reason, I thought that Flint was another flattie. Quite obviously, it isn't, it's got a shallow V on the bottom.

Ross, just as a matter of academic interest (ie, I want to learn something), how would you expect a hull like Flint to behave compared to a flat bottomed hull like the Seagull. I realise that it'll depend on beam and width of bottom plank and depth of the V and all that, but basically, how would the shallow V hull differ from a flattie when used on a rowboat (ie, narrower beam than a sailboat)?

Richard

Richard,

"Flint" is very deep and fine in the V-sections for'ard, flattening to a moderate V in the middle and aft sections






The boat was designed in response to a request from a bloke who had built a "Seagull" and found that she pounded seriously in the Moreton Bay chop between Russell Island and the mainland, and got blown away badly in a cross-wind or quartering wave pattern. I made the sectional shape of "Flint" extremely deep and sharp for'ard, but used enough rocker to bring the heel of the stem to the surface with the middle of the boat immersed to the chines or slightly deeper). The transom is above the waterline and she is double-ended at the waterline.

The combination of the extremely sharp forefoot and the big skeg is supposed to keep her tracking well in waves, but the pronounced rocker is there to concentrate dispacement in the middle, and allow her to manoeuvre under oars.

The original builder reported that she tracked nicely in adverse conditions, and that she doesn't pound

There are plenty more photos of the boat (as expandable thumbnails) on my website Bayside Wooden Boats Ross Lillistone under the button labelled "Flint Photos"

Ross

Thanks for that Ross. Much to look at and think about.

Richard

What I should say is that I did not mean to criticise "Seagull" as a design - it is just that she wasn't suited to the choppy conditions this guy was operating in - I think she would be fine on flat water.

Ross

Can you do this in a Seagull or MSD?

Great picture for a rowboat

Tom's MSD in Brisbane. With the way the bloke in Flint is leaning back, there's not a lot of difference

Both men look terrified of getting wet

Regardless of pissing contests, the Flint photo IS a good advertisment for the boat and it's one I latched onto.

Can we all join in this competition? How about two of use taking 18 months so far, and we have just managed to plank one Oughtred Snipefish hull !

You can try for the record, but I should point out that so far, Midge has yet to complete the first prototype of the Eureka (that's right, the original one)

Richard

Back to Ross' Flint (I'm limited for posting time which is why this discussion is stretching out over days).

So the Flint's hull was designed to handled choppy water. Am I correct in imagining that it's the shape of the front end of the boat that gives it this ability?

What do you need to look for to get stability (tracking, not rocking and rolling) in windy conditions?
