'mini cup' sailing dinghy
 

Any thoughts on this dinghy;

http://www.stevproj.com/FastSailrs.html

Its the second one down on the page, the 'mini cup'. You have to
download a 2mb pdf file to see all the plans for it (which are free),
but there are a couple of pictures you can see if you click on the link
for pictures. It looks a lot faster than the scows Ive been looking
at, and not really too much harder to build.... but the sail! Horror
of horrors, its a nasty looking piece of work, but will it work?

The wing dinghy on the same page at the top looks like a lot more fun,
but a bit more work to build also. The plans are cheap enough at $25,
but they're out of stock :-(

Thanks,
Shaun

I love my MiniCups and I built two of them, a trailer to haul them and
a dolly to carry them to the water. I have built several iterations of
sails for them. They sail very well.
So, get the plans but do not strictly go by them because they are for
1970s era boatbuilding methods.
Here is my site for MiniCup building:

http://home.mindspring.com/~ohara5.0/

At the time I wrote it, I did not have much experience with epoxy and
fiberglas so I couldnt properly glass them. I am now glassing them.

The visqueen sails work ok but soon fall apart as the duct tape fails
in water. I tried various things as I discuss in the site. Currently,
I am using sewn polytarp sails that work very well. My next project
for them will be reefable sails. I have used my MiniCups so much that
they are nearly worn out which is why I am now rebuilding them with
glass.
Andrew Butchard also has good info on his MiniCup building.

Good Luck and have fun

Hi David,
Thanks for the info! I had a good read through your page and learned a
few things~ The links that you mentioned seem to be down though.

How do you find your minicup handles compared with other small dinghys,
especially to windward? Im a bit on the large side myself at 6'3" and
230lbs, so im wondering if this boat is quite big enough for me. It
looks to have plenty of flotation.

when you built your boats, what ended up taking a lot more time than
you expected, and what was the biggest blowout on the budget side of
things? Im hoping to get a few friends together and all build the same
type of boat so that we can race out on the lake near us, Ive already
talked my uncle into it and may have acouple of guys from work. If
things dont turn out right in the end though, I run the risk of being
drowned in the same lake by this group of guys ;-)

Thanks,
Shaun

Windward performance? Well, She does better in more wind, say about
12-15 mph although I have done a lot of tacking to get places in very
little air. With the lateen sail, I have difficulties judging how
close I am to the wind. I really like the lateen sails cuz they are so
simple.
BTW, one of the best things I did was to place tie downs for a small
paddle on the deck forward of the cockpit. I have used this paddle a
lot when the wind died and I was waaaaaay out in the lake. She
actually paddles well.
As far as what cost more than expected, that is hard to say because I
did so much experimenting. The polytarp cost more than expected but I
forget how much but it wasnt a real factor. I think the MiniCups
should be epoxy/glassed with 4 oz glass and if you do so you will
probably surprised at the cost of epoxy and glass.
I have recently taken all of the foam floatation out of my boats and
have sealed the floatation areas very well with glass and epoxy. I
have put in screw-in access ports because I think you need to be able
to look in to see rot and other problems.
I weigh about 187 lbs and I have easily carried myself and my 130 lb
wife in her too.
Definitely reinforce the tiller, the rudder box and the method used to
fasten the rudder to the hull. The way the design call for the barrell
bolts to be fastened directly to the hull will cause quick failure. I
think you must use very robust fasteners here backed up with something
strong.
My 16 yr old son says he likes the MiniCups better than the sailing
clubs Laser because it is easier to handle and has a lot less
"adjustments".

Thats good to know.
Any ideas about maker her a bit more of a light-wind sailer? The winds
we get on our lake are usually more in the 5-10 range, and sometimes
even less than that :-( it seems there's either very little wind, or
there's way too much. probably the main reason i only see people
fishing and water skiing out there!

have you seen any with different rigs?

Thanks,
Shaun

You could make the sail bigger. Mine do not go all the way to the
back of the top spar. It really is already a big sail for the size
boat. Heeling her really helps in light air cuz it reduces wetted
area. In 8 kts, she sails very well. In 4-5 kt, she does move along.
The normal problem with lake sailing is the fluky winds and wind
shadows from trees. This is one reason for the paddle.
Basically, I'd go with the visqueen sails and make em as big as you
can. Then when you see what evntually works best you can make
somethign more permanent.
I have never seen any other MiniCups in person. I considered making a
conventional triangular sail with a boom and a jib too but that would
require some shrouds and a fore and back stay simply because I am used
to sailing a much larger boat like that. However, the lateen sail
really does give more sail area than anything else I could easily
build.
I think she sails well in light air and when you get about 9 kts and
look back at your wake you'll be amazed. Above 12 kts, the weather
helm really shows and you really have to hold the tiller and it will
try to bend to make her round up into the wind. Around 15 kts, it gets
exciting.
As you can see, I really like my boats.

The MiniCups were the first boats I built. After that, I built a
nesting dinghy for my 28' sailboat called a Two-Paw-9. Then I got
really ambitious because I wanted a power boat for exploring the local
coastline and spent a year building a Tolman Skiff. The boatbuilding
thing can really get into you and you dont want to stop.

Tomorrow, I start glassing the deck of MiniCup #2.

BTW, instead of screws, you might want to use the silicon bronze ring
shank nails (A box with sufficient 3/4" nails is fairly cheap) from
Jamestown Distributors to fasten the stringers to the bottom. Of
course, the stringers should be glued with epoxy as well. When you
fasten the sides, you will use screws (and epoxy) because they will
pull the sides toward the stringers. I should have mentioned Jamestown
Distributors as a source for epoxy and glass.
