Last spring my daughter, SIL and friends formed the Coeur d’Alene Youth Sailing Association (non profit to teach kids to sail on Lake Coeur d’Alene). They encourage the parents to provide an Optimist but the only requirement it a life jacket and a parent or responsible adult be present when sailing. They had for the summer 5 Opti’s and 2 Lasers for the kids (3 Optis from parents Dan found 2 used in the Seattle area and he had 2 Lasers They had 8 6 to 8 yr olds and a couple of teens that used the Lasers. They had fun over the summer sailing Weds and Saturday.

A little history on the Optimist is necessary here. In 1947 the Optimist club in Clearwater, FL felt they needed some activity to keep the kids in town off the streets and thought sailing might be a good activity. They had no affordable boats. They went to a local boat builder named Clark Mills and asked him to design a small sailboat that could be made for under $50. He designed a pram that could be built with 1/4” plywood. The boat worked well and a lot af kid’s parents built the boat and kids sailed it. In 1958 a Danish tall ship Captain visiting the US saw the pram and asked permission to take one back to Denmark with him. He made some modification in the rig and renamed it the International Optimist Dinghy (IOD). It spread around the world from there. The IODA governs racing for 5 to 15 yr old internationally.

I received from my SIL a subtle hint in the form of a link to plans for an Optimist. In researching things I found the Cleveland Area Boat Builders and Boaters Society had the plan for much sell than the original link. I ordered a set of plans from them and started building the boat in October
I built the boat from 1/4” exterior plywood and eastern red cedar. I used the eastern red cedar because I had stack of it in my garage.
The strongback (the frame that keeps the boat straight and square was from 2×4’s and 2×6’s from Lowe’s (picked their stacks over for straight ones) and got enough to build a strongback. For the mast I found 2 knot free and straight 2×4’s glued them up cut them down to a 17/8” hex and went to work with a spokeshave, 80 grit sandpaper and a small board with a 13/4’ hole in it for a template made a round mast.
The exterior was skinned with 6oz cloth and fiberglass resin (mainly for abrasion resistance on the bottom), then primed and painted with Interlux 2 part epoxy. I had used fiberglass before in atching my drft boat but this was my first big project I got a real education in it and the 2 part paint. It is abut a 20 ft paint job. It looks pretty good from about 20 ft away. The interior was finished with spar urethane that came out very nice. I enterd it in the local Artistry in Wood show this weekend and picked up a blue ribbon on it. I was pretty happy with that. It meant I did a good job in hiding my mistakes.

I will take this to Coeur d’Alene next month and launch it and find out if it will sail. I know it will float but not sure about the sailing. My grandson will be able to get out of the plastic boats and into this and it gives the CYSA another boat for kids that don’t have one.

I may end up taking the strongback to Cda this summer and helping build a boat up there. The boat is fairly simple and can be built in about 40 hrs with a little help.

I got an education in fiberglass

These are wonderful. I wish there was a program like this where I grew up.

Wow Bruce what an exciting and worthy venture and best of all your SIL is in my neck of the woods helping our local kids. Perhaps we can connect when you come up. You did a great job building that dinghy. What do you estimate the material cost to be?

Congratulations on a great build. You are way ahead of me. I started one called “The Mini Cup”, that was in an old Popular Mechanic magazine. I started it 10 years ago, the hull is done except for the final paint and the centerboard and rudder assembly is done. All I need is to build the mast and sails… And there it sits…

I did build a skin over frame kayak, could not use it because of a bad back, so I sold it to a guy last summer from Coeur d’Alene. I live close to the Tri-Cities in WA. He sent me pictures of him paddling it on Lake Coeur d’Alene.

Very fun build. Building it with the kids would be a great way to get them even more excited about sailing.

First of all, Beautiful!!!!!! Great job.. Pretty sure, I saw a sleeve for a center board. Great for the kids. I too it turns out to be an easy sailer. Where do you get the sail?

What makes this so interesting to me, my wife is from Eastern Washington. I spent sometime on Coeur d’Alene lake. Even played a little golf on the resorts course.

I also was a sailor; had an O’Day Mariner. My sailing experiences were on the East Coast waterways, Cape Cod,Hudson River (West Point down to NYC), and the Jersey Shore.
