Congratulations to Charlie Patterson
of Stone Mountain, Georgia
on his progress towards completion
of his 12' Classic Dinghy.

Dear John

I'm at a point where I need to decide on sails and hardware for my project. I've been surfing but have found nothing that seems close to what I think are my sail needs.  Would you have more detail plans or suppliers where I could go? I suspect I'm looking for a single sail mast that does not require stays.

The hull turned out nicely.  I'm including several photos to add to your collection of satisfied plan users...Charlie Patterson

Note: Hi Charles...The photos of your 12' Classic Dinghy hull look great!  Looks like you have done an excellent job of boat building up to this point.  I wish I could help you more with sailing plan information but I just don't have much.  The only information I have available is the sail plans in the Classic Dinghy manual.  These plans show all the technical info, dimensions and areas you need for building one of these plans.  Unfortunately, since I haven't built one of these sail plans myself as yet, I don't have any photos or construction details to help you with.  I keep waiting for someone to finish one of these sail plans and send me a series of photos and info that I can include on the web site.  Maybe you will be the first one to do that, hopefully.  You might try your local library section on boats and boat building.  Go through the different books that show sailing dinghies and try to find a plan that interests you, then copy it.  The sail plans in the manual show you where the center of lateral plane is on the hull.  Any sail plan you build will work well if you keep the center of effort of the rig forward of the center of lateral plane by about 6 to 8 inches.  A dagger board setup works well for any small sailing dinghy and is easy to build.  The dimensions and location for the dagger board are shown in the sail plans.  Of the different sail plans I provide in the manual I like the Gaff Cat rig best and it is an excellent type of sail plan for a small dinghy.  One of these days I hope to get around to building it myself.  Hope this helps a bit and please send photos when you have them.

Well.. I had already figured that the gaff rig would be best... also had figured out the center of effort/dagger board relationship. I can do it... was hoping that you might give me info that would require less hoops to jump through. Will send pixs of the finished projects with all hardware suppliers etc.. Charlie




Dear John, 
This boat is finished except for the sail that has been on order for a month now. It looks pretty, don't know 
if it will sail as good as it looks. Haven't even had it in the water to try oars. I did a lot of research in trying 
to come up with a good sail plan and specs. Mast, boom, rudder, dagger board, hardware, rigging etc.  
I'll send these when I get the sail fitted. It may help someone else who is working on a similar project.

Dear John. 
Well I have finished the Dinghy. Ready for the Fall winds, and my three grandsons. I hope it sails as good as it looks.
  Since your book was a little short on rigging details, I thought I would contribute my ideas. I was designing for a 700 lb load, The  6061 -T6,  2" X..065  12' mast exceeds this. The boom is 1-1/2" and gaff is 1". The gaff shape  sail is exactly as designed in your book.  The sail is designed to collapse with boom and gaff folded against the mast, and the sail wraps everything.  It weighs 15 lbs total and three boys age 12-10-8 should be able to manage it   The dagger board weighs 15 lbs and has a capture device to hold it up about half way, about the same depth as the tiller,  just short of the mast swing. This is to help with shoals in St Andrews Sound  Panama City, where this dinghy will reside. The tiller weighs 10 lbs and the attached bar will swing over into a reasonably compact shape. It's fitted with oar locks and could handle a motor, but my son who is a true sailor ( he has a 36' Morgan) says the little boat is too pretty for that. It's going to be a tender for the 36'  "Cat's Meow" , I suspect it'll be named "Cat Nip". Again Thanks for a nice set of plans.
