Boys and their toys...

Hello...

I am just now designing a hull and build frames for a 48 inch model sailboat for my shop supervisor - not as easy as it all sounds...

He just wants something big and fast - just wants to sit in his chair on his dock at his cottage and F'ck around - nice open design brief...

Thing is - I realize just how 'set up' I am for doing this - I inhereted a 42 inch by any length plotter from my retired Husky Oil draftsman friend - and its a damned fine toy...

So - whats wrong with designing toy boats...

What thoughts...

Cheers...

are going soft???

 

AS RC model boats go 48" is not big. Some of them are as much as 96" LOA.
There is a good resource at AMYA.org. Look up the IOM class. That's International One Meter. These are small one meter long boats that are developed far far beyond the toy range. They are actively raced all over the world. Reference to the IOM or the one meter US1M class will get you some good working ideas and probably save some time as well as possible angst. Either of the meter boats are pretty fast for their size. Scaling up a good meter boat will produce a faster boat still. If you want really fast then consult with Doug Lord who is the resident model go fast guy. You will find Doug in numerous places on this forum. Your shop supervisor should be ready to spend more than lunch money on this project. For example a good sheet winch is priced at about $200. Other stuff costs plenty too.

I warn you that if you get involved with models you may find it habit forming.

 

In a single word------Nothing.



Just consider it a precursor to the real thing.

Who wants to design, build or buy square rigged pond boats?

Go to <modelsailingships> They are big and beautiful BUT who would like to design and build something similar but weighting 30 lbs. ready to sail?
Or if you want to buy tell me what your specs are so we can see if enough folks want the same thing so we can interest a builder/seller.
Rig? weight RTS? lwl? draft? freesail? radio control? etc.?

3D paper model

on the one hand, with the plotter you are able to construct a 3D paper model isn't it

on the other, your design brief seems simple and allows you to move fast,
interested in the design of a RC model and in my humble opinion it seems that you need to take more parameters into account the "fast" alone
strange that there isn't a sailor chick mentioned in the requirements,
seems very challenging also
but as you are already building it seems to me that you have everything sorted out already. enjoy the construction of the RC, hope that it will not fail to sail
if you like to go the easy way look at the volvo ocean race website,
in the shop you can buy a very fancy RC boat.
seems that you can control the two rudders and it has a cantle keel also,
wondering now what extra design parameters are still needed ?
- but that's probably already implemented in your model already -

 

design parameters


RC design parameters,

1.do you want to compete with other RC boat owners if yes => what RC class do you target ?
2.are there certain RC class building restrictions ?
3.what scale factor will be applied ?
4.where will you be sailing with the RC model ?
5.what will be the dimensions in the metric reference ?
6.what will be the targetted weight ?
7.do you need replica's of the original design - impacts the master?
8.what about the centre of bouyancy and the centre of mass ?
9. what about the hydrodynamic and aerodynamic inter working from model point of view?
10. how many sets of sails are required ?
11. fixed keel ?
12. canting keel => simple or complex design ?
13. type of rudder ?
15. daggerboards ?
16. rotating mast ?
17. extra stand alone electronic control inside the hull ?

would like to further elaborate.

Best Regards.

 

Nope...

Hello...

I do not even remember starting this thread...

It is all done anyway - see http://www.boatdesign.net/gallery/showphoto.php/photo/12467/ppuser/3673 ...

Also some build shots...

Thanks...

A square rigged mistake

AquaCraft designed, produced and sold a square rigged Pirate ship called "King's Ransom; it looked pretty good but was a FLOP because of inadequate design (insufficient stability). So is anyone up for designing a good sailing square rigged model? My ideas as to specs are: ready to sail weight 25-30 lbs, waterline length between 36 and 40 inches, rig: ship or brig.
But the big question is how many of you are interested in obtaining such a model? I am talking with a manufacturer of fiberglass in-the-water models, both power and sail. Thus (as to sail only) I hope to get some feed back from you as to what YOU want and how much you would pay for it?
Length, weight, rig, draft etc. a short kit, a full kit???
Thanks
