flaxbybuck asked: " I am interested to know how you have arranged your sheets such that your jib sails are able to overlap. I have not been able to get sufficient slack on the windward side sheet."
I initially ran into the same problem.
As you know, the sails using booms are relatively simple since you only need one sheet to let out or pull in the boom. It's self-tacking because the boom swings all by itself to the other side when tacking.
But overlapping jibs require separate sheets port and starboard. Pull one side tight to set the sail, while the lazy sheet on the other side is let out loose.
My winch servo provides 18" of sheet travel. So when I first did mine, I figured I could have 9" of overlap on the jibs. Nope. Like you, I found out there then just wasn't enough slack on the lazy sheet. D'oh!
I had to stitch up a new set of smaller jib sails, so they overlap less. See image attached.
I use one winch servo for the boomed sails, and a separate winch for the flying jibs and fisherman staysail. See the image with the coloured sheet lines. The red line is the sheet from the winch servo, pulling in or spooling out 18" of travel. The mate to it on the other side runs in the opposite direction.
That red sheet line then splits three ways. The blue runs to the jib staysail (the middle jib), the green to the jib topsail, and the yellow comes back to the fisherman staysail so I can pull the foot of the fisherman to the correct side of the mainmast.
I added bowsies into each line so I could make adjustments to each individual line tension. But I still need to make some changes there to lengthen each line. Studying my videos, I can see the wooden bowsie blocks need to be repositioned as they sometimes snag on other lines.
p.s. I don't know why my previous post got truncated. The standard design should weigh 25lbs, but my modifications brought the boat up to nearly 28lbs.

luckyduck asked: "how have you made her so light for carrying, and yet stable in a wind, cannot see a deep keel? "
Ha! She's heavier than she appears, or I'm stronger than I appear.
The boat, in its original 3-sail configuration when built as designed to the plans by Gary Webb of Bearospace Industries weighs 25lbs. She has a long aluminum keel fin with a heavy lead keel bulb. (

This guy engineered a retractable keel fin and rudder for his Irene schooner.

Gary Webb's Bearospace designs are awesome and easy to build. I bought one his Irene schooners plans and built that. After a year of sailing that I modified it by adding topmasts and more sails.
Here's a playlist of videos of the boat in action.

Gary Webb's Bearospace designs are brilliant and simple to build. I chose his Schooner Irene design as my first attempt at building a model sailboat. The original design carries three sails, but I subsequently modified mine with the addition of topmasts to now carry a total of eight sails.
