Really like what you are doing. I have a CAD (STL) model of the Sunfish that is pretty good - only has the hull and sail, but is still useful. I found it on one of the 3D model sites. See attached. The printed parts below were made with PLA (red) and PETG (clear). The mast and sail are...

We offer a few simple parts now for the Sunfish and Laser made with a conventional 3D printer. See aerosouth.net We'd rather have them injection molded as 3D printing is glacially slow and strength is limited on standard 3D printers. When our sales volume can justify it, we will have molds...

The FOILSZ kit from KA costs AU$ 3625, around USD $2700.

Based on initial user comments, we've tweaked a few things on both our FS rudder blade and the Sabre daggerboard. Otherwise they are performing well. details at aerosouth.net Thanks to all here for the inspiration, comments and support. In the AeroSouth Skunk Works now is a mod/kit to allow...

That is an interesting observation. Look at it the other way - keep your hard-earned weight and beat the skinny kids!

Thank you CC. We are pleased with the results. As with all new innovations these will evolve based on user input. Anything that reduces drag is guaranteed to improve speed, so we're fairly sure that people will notice the difference. Lookout Lasers!

Dear friends, with our new "FS" rudder blade in production and the new daggerboard in testing, I thought others would be interested in the details of our efforts. I attach here a report on this, which can also be found as the last PDF on the list here: https://aerosouth.net/media

Wow - I am impressed. Mees-eh-Gah-Days is how it is still pronounced in Germany. There are a few members of the family still there, near Bremen. In the US it is pronounced Myz-Gaydz, don't ask me why. Living with this really odd name is somewhat like the Johnny Cash song "A boy named Sue" -...

Howdy Cactus Cowboy - thank you for your kind words of encouragement. I am fortunate to have a few friends who really know their stuff when it comes to sailboat hydrodynamics, and they have been very generous sharing it with me. Especially Joop Sloop, who is finally getting the credit he...

Dear friends: We are pleased to announce that our new "FS" series of recreational rudder blades are now in pre-production. While these are for the Sunfish, we know that many Laser owners also sail the boat. Longer term, we plan to apply the knowledge gained from the design of advanced rudder...

An update on the new Sunfish 'Sabre' rudder we're developing at AeroSouth. Below is a picture of our first rough-cut 'Sabre' rudder fin for the Sunfish. Solid poplar is being used only for setting up the 5-axis Homag mill and fixtures. The actual parts will be made from a laminate of Sapele...

Great timing - Yesterday I was sailing on Lake Auman, behind our house here in Seven Lakes, NC. 100 feet deep at the dam. The wind was up and gusting. I like sailing fast and push my old Fish pretty hard. While reaching hard, the spruce mast snapped at the deck with no warning. Thankfully...

An update on our new Laser components: our sheet clip and mast hole plug are now available at https://aerosouth.net/sailboats We are also making good progress on the new 'Sabre' rudder fin and dagger board for the Sunfish and have started designing the same for the Laser. All for...

Very nice. I did something similar on my Sunfish, which comes with a highly swept rudder fin guaranteed to create weather helm. The foam-and-fiberglass process from aircraft designer Burt Rutan was followed. I kept the overall area and draft approximately the same. It lowered weather helm...

I will look at both designs in comparison to my clean-sheet Laser rudder fin, which will likely appear similar to the ‘Sabre’ rudder fin I’ve designed for the Sunfish. See some details at Aerosouth.net.

Nice. You made a new rudder fin, correct? What materials did you use? Are there details on Mr. Kirby’s design? Thank you.

Thank you! That makes sense as it is a popular airfoil for airplane control surfaces.
