That was a fake statement.

But I wanted your attention without having the person meant, around here.

We are about 17.000 registered members here, and only one is a kid! Mike
or mgriffin, or formerly confused, now 13 years old.

and "building a boat at the age of 12"

have been the places he told us about his dreams and plans and phantasies. A young boys phantasies of course. Not mature, not very sensible...dreams....
Being a bit stubborn he did not always follow our advise, did not make use too much of the hints given, and decided quite often to go the opposite direction. A child, acting childish. That is his right. Though we are not much amused, we have to understand that. Many of us, I guess, have not been different.
He tried to find a suitable boatplan, but of course, was not able. How could he be? He does´nt know what suits him right. We sometimes hardly know.
And if he found a cheap plan he tried to make so many changes that the result would have been a catastrophe.
PAR, marshmat, CDK, rasorinc, so many others, did contribute to his threads, and I see he is doing a bit better in listening to advise. But still has no proper plan (and will not be able to afford one).

Now this boy is moving to Texas as he told us, there he will build a boat, there he will have the chance of using a boat. He is longing for that for long time now.

When you look here:

..and try to read between the lines, you´ll notice that it is not unlikely that much will remain to be a dream.
sad...

In my village we have a tradition, every year at the 24th of December we celebrate Christmas. Then we make some presents to our children. A nice custom.

You have a idea why I did not want him to stumble into this thread???

_____________________________________


Would´nt it be worth, to support the only kid we have around here, staying stable with us for almost one year now (what a long time at that age). He never asked for anything for free or getting a discount!

My (first and broad) suggestion:

You Designers, stick your heads together and bring out a set of plans like the little Tug we have seen in one post. Sure he cannot build that! But he cannot build a smaller boat either, so:

You Boatbuilders there in the south of USA, free up some space in your shop, put a tent in your garden, offer Mike to do the boat with your assistance! Hmm, yes I mean, he will assist you, in his holidays. Be sure he will!

You, Boatowners, Boatlovers, Bikers, Artists, Acrobats and all the other boat infected in the USA, lookup your shop for a engine, shaft, prop, you know....

You, the rest of us, we open our wallet and spend some pennies for the material.
Just 200 of us with some 5€ each would make a lot of wood and resin. Or steel and sticks...

Who has a Paypal account in the US and is willing to collect the money?


Any suggestions?


Merry Christmas

I think this is an excellent "bringing to the attention of others" thread.

This boy needs support and guidance..surely there must be someone on this forum close by who can help, guide and encourage him in the direction he wishes to go?

I have done this many times to "children" who lives near me when i was in UK, we even went to our local school and gave talks. So much so, their end of year project was, and still is, design a boat. (This was 8 year olds!)

Unknown to many, i have given guidance to others on this forum, privately, to assist in their education and career....because, that is what we are all here for...to guide and help those that require it, neh?

Lets hope someone lives near by or is able to drive 'down' and help out...

Maybe we should try to connect him with the people over at Duckworks,

http://www.duckworksmagazine.com/

There are a lot of people on that site building simple, cheap, boats. Some of them even seem to be from Texas. Maybe he could get connected with one of those PD Racer types, can't get much simpler and cheaper than that.

lets first see if we can get a proper plan, then we will know the demand for the boat. But of course it would be nice to know already where to send the stuff needed!

Mike knows about Duckworks and it does´nt solve the prob bringing him in contact, when he has no internet connection.

Playing Devil's Advocate here:

1: the boy is a TAD Stubborn
2: He wants an 8 ft or so INBOARD
3: did I mention that he is Stubborn?
4: Provided a suitable design was forthcoming, sufficient supplies acquired, and a place to build found with lots of help...
Who's going to ante up when the (did I mention he is stubborn?) young man lands himself in the hospital or in the hands of those who come after and the parents would like to exact revenge/retribution/wrath from above on all those who so kindly landed their loving and sweet child in the temporary or permanent fix he is in. Do we even know if his parents are on board with this or...? So many questions...so little money for lawsuits.

Richard I think that picture is one of the few occasions when seeing snow is alright.

I offered him (Michael) a little harbor tug sort of thing in one of those threads. It would have been easy to build and not costly. So, I guess I'm in too.

I think we should do it in one of the gator filled lakes in his area. Unlike a great white that will spit you out, after a quick taste test, a gator likes the flavor of humans (taste like chicken) and usually will attempt to have a feast on an unfortunate water mishap. His young hide would be especially tender to a gator I would guess. In other words, who needs lawyers when the law of the lake can sort things out fairly quickly.

Well, I'm new in these forums. But the idea pleases me.

I'm no designer, and I'm too far from Texas to lend a hand. But I'll pitch in a little geld, if the project gets off the ground.
Damn the attorneys; full speed ahead. A fear of shysters is a piss-poor foundation to build a life on; I'll take a chance the kid will survive our generosity somehow.

I think every young man can have a world of good done if they get the fear of God put in them early in life. Mine came when I realized other people were shooting back at me. Embracing mortality is a good thing for kids. For what it's worth, there doesn't actually have to be any gators present in the lake, so long as he's in the water and thinks there's man eating gators there.

This is the one I posted, though I think he wants something different now. At the time we'd talked him into an outboard and a little length to make life a little easier on him. This had square sections, a 48" bottom panel and full standing headroom at an enclosed helm.

Now I think he wants the inboard again, with enough hull rocker to protect the prop (I don't think he understands the idea of a skeg), still the 48" bottom panel and square sections for ease of building. Unfortunately, he's selected one of the most unsuitable designs he could have, though I think he now understands this and needs to rethink his requirements a little.

We do need to some how get a email to his parents I would think.

Yes he did not like the OB idea, I remember. But I know him good enough to be sure, when he gets this sort of "package" I have in mind, he will surely not argue! So, lets forget about another propulsion if this becomes our design to go for!

I´ll try to contact the parents!

That design brings up some bittersweet memories; it looks remarkably like the mini-tug one of my younger brothers always wanted to build. Unfortunately his drinking took him out in his mid-fifties, before he got it done.

PAR
11-06-2009, 05:07 PM
I find that I get much less information about a hull with modeled surfaces that have too many lines. My eyes can't follow what's really going on. For example, your FreeShip model, I can't really tell what's going on with the deadrise, it looks constant, but I can't tell. With a plan, profile and section drawing, I can tell exactly and even see the angles and curves in relation to each other. I guess I'm old fashioned too.

PAR
11-06-2009, 05:52 PM
Richard has a building method been decided? Taped seam would keep the costs down, but he'd have to fool with goo. Plywood on frame would cut down the goo factor, but he'd have to make frames, floors, stringers, etc. making the materials and building effort go up. I'll assume taped seam for now.

Agreed: I prefer to use the default settings of Free!Ship for the non-perspective views but they are not so pretty and the application let's the user change them freely. Which design application are you using? It makes nice drawings. I don't have anything that does clean drawings in a form I can print or put on the Net; I use Presentations but it's not good for accuracy.

Question: Which method would be the simplest for a 13 year old to understand. For such a young builder, skin on frame might be easier to do. Remarks, please.

PAR
11-08-2009, 12:16 AM
I've been debating this in my head. I'm inclined to agree that plank on frame may be easier for little Mike to get his head around. Then again, he's the type that may just like to play with goo. It's not especially hard and before long he'll be fixing and molding things out of the stuff for other uses. It would be cheaper and lighter to building taped seam. I know these are concerns of his.

On the other hand, cutting a 2x4 to length and screwing it to the boat is easy to comprehend. A plank on frame build will be considerably heavier then the other, maybe too heavy. Another consideration I've thought of is parent participation. The parent may have issue with epoxy and can wrap their head around plank on frame more easily.

Grant Nelson
11-08-2009, 12:14 PM
That was never planned! And sure would´nt be sensible.

Ah, right, it was a bit hidden in your original message, and a few persons replied accordingly, but by page two it was all about a boat plan, and I felt it did not make much sense to discuss the design, unless, like you suggested, someone near him offer face to face building assistance. So, I hope the thread gets back to solving that first, then we can think about plans, but more importantly, money for materials...

Still, perhaps a boat program in the area would be the best and easiest solution...

Cheers,

Grant

pointing the guy to free delftship if he isnt using it allready may be an eye opener of an idea?
to me it was and still is about the best gift i ever had and a interested 13 year old can learn in a week
and my last drawing should be to what size plates o great old grandmaster par? lines bling but ok?
its wise to close some leak points and play around a bit with delftship before taking the tools out
but to get the plates (layers) out of a quik one layer drawing like i did is easy, read this:


from manual
"You can identify which layer is active
by looking at the layer toolbar at the top of the screen (illustration
9.10) This contains a list of all layers, and only if no faces are
selected it displays the name of active layer. You can modify which
layer is active when no faces are selected by simply selecting
another layer from the drop down list in your toolbar.
If the event that faces have been selected there are two
possibilities:
● All selected faces belong to the same layer. In that case the name of that layer is shown,
even if it is not the active layer.
● The selected faces belong to different layers. No layer name is shown in the toolbar at all,
it will be blank. By selecting a layer from the list with layers while faces are selected,
all the selected faces will be removed from their current layer and assigned to this selected layer."
