Footy plans

Can you still get freeship? Where?

thx

I understand what you are using the locating pin for. But from the drawing, the pin doesn’t even reach the bottom of the cross-junction, and the mast looks like it needs a tube fixed in the hull, right? that’s the tube I’m talking about. Bill’s comment about drilling holes in the bow means he would drill through-holes for the locating pin. This is fine, until you find the place where you will keep the mast & pin, so it could easily be finished off by using a thick doubler under the deck. That way only a deep hole is drilled for the locating pin, and one could finish that off with a brass or poly liner, or coating the hole with CA.

Also, for the pin to fit into the deck, as in the drawing the forespar would have to be square to the mast. Can you tell us the approximate angle of the forespar/mast joint? Is the aftspare the same?

thx mate BTW, I use a program call “Free DWG Viewer” http://www.bravaviewer.com/free-dwg-viewer.htm Which has excellent detail and You can save (current screen) to jpg

Sorry if the plans don’t have enough detail for you.I think they are way better than most I have seen.
Nevermind,I tried to provide a easy to read construction plan,many ppl have successfully built the boat from the plans.

I have a new plan in the works and thoughts on a series of articles on designing and building a Footy.

Sorry about the delayed reply…didn’t see your posts until now.

Gio, starting mast position should be about 5" back from the bow. Optimal position is something that usually takes experimentation, and depends on the CE of your sailplan.

Fin position should be based on the positon of all the gear in the boat. put everything in (sails and all, or equivalent weights in correct positions) then float the boat with the bulb inside the hull where you think it should go. Adjust the bulb position until the boat sits on her lines properly. Mark the bulb position. Install the fin so that the bulb aligns with your mark.

I make my fins from basswood about 3/16" thick, sanded to a wing shape. I don’t think balsa is stiff enough. Based on Brett’s recommendation, try 6" long.

For both you and Tomo, I suggest using the sailplan and radio gear layout from Brett’s BobAbout. Since the displacement of both boats is 500 grams, the sailplan works fine on both.

Other than those suggestions, I leave radio gear, deck layout, etc. for you to play with. Part of the fun is making your own boat unique. Apparently it dissapoints some people that my plans aren’t completely detailed. That’s because I’m not in the plans business. I just share what I make for myself. The design software that I use helps design the hull, but it doesn’t make construction plans. I position radio gear, build the fin and rudder, and determine mast position based on whim and trial and error.

Have fun…Bill

Bill, thank you for the replay.
I already had the mast placed, fortunately 5 inches from the stern as you suggested.
For the keel I have two options I made a hollow one with two 1/64 thick ply skins like the one in the USOM guide. It’s a little heavy (I guess), but wery stiff. Option two I found a helicopter blade out of wood, that wery light and with a light epoxy coating should do the job. I have to figure out witch one to use now.

Besides Brett, whose got plans for sale?

thx

Here’s Brett McCormack’s BobAbout in .dwg format for CAD systems.

Are the plans available as a .dwg? I have only seen the .jpg version that is of such low resolution that it not readable.

I don’t think it would be stretching the imagination too far to consider my ‘ScaleSailing’ hulls as ‘3D Plans’. The hull sets are described here…
http://www.scalesailing.com/sskits2.htm

The hull skin shapes (typically 1/32" ply) are obtained by simply drawing around the foam core directly onto the wood. The instruction set deals with constructing the hull alone rather than the complete boat because these hulls are aimed at you guys wanting to do your own thing with the rig etc. Fin size and position is described. Reduced drawings of the Kittiwake and Pintail 12 rigs are also included along with the radio mounting plates drawn full size.

Hull and instruction sets come at $18.95 plus shipping.

I hope this isn’t considered too commercial for this forum…
