For holding the mast up I use non-stretch cord (fishing tackle) as unobtrusive as possible, referred to as shrouds. It will probably need bowsies for adjustment. Bowsies are frequently made from white plastic. If you use white they show up big-time on photos. I buy mine and prefer black as they do not show. It looks untidy just to have them at random distances from the deck so cut the shrouds the same length and keep the adjustment range just enough to make the securing hook easy to remove.
If you are suffering from the condition called 'Old' you might find it easier to have the bowsies at the top of the mast. For my yachts most from 24 to 40 inches long I make the shrouds and the deck location eye very strongly so that I can launch a yacht just holding the mast with yacht hanging below.
Just screwing in a metal eye looks crude. If you first place a small washer onto the eye and a touch of glue on the thread it suddenly becomes an acceptable fitting on the deck.
When you have finished the build and tested the workings and are ready for the lake, do the upside down test, nothing should move! It is a precaution against sudden heavy weather, it happened to me once on a lake and I was lucky to get the boat back intact. I had Captain Kirk in civilian clothes at the helm and he was lost overboard, never to be seen again!

The string that runs between the mast and boats side is it fishing bride or sone other cord? Col
If the price is right I may have a winch and rudder servo that one of the members is selling Col

I know this 3d printed schooner is an experiment. If you have followed the last couple of Gary’s videos, his final flat bottom models had several different sail designs tried before deciding on the one he liked best.
Following his method of making DIY cotton sails, it’s possible to make a variety of different styles.
I use a tube where the hard plastic hinge pokes out of the tube at the bottom. I drill a hole in the lower end of the hinge and this has a removable hook which has a rope to the boom so stopping it rising up.
Painting to match the mast makes it almost invisible cost is very low. Each element of the plastic circular section hinge is about 30mm. and about 3mm diameter and they are very strong.
I think my 'fitting shows if you magnify the picture.

I'm working on the lower boom* mounting block.
will it require a three-way movement
Up and down, left and right with a twist on the boom
or can I get away with just two
Up and down left and right with the hoops on the boom taking care of the twist Col
* I think the rod at the bottom of the sail is a boom
Don't know if this helps.

I'm thinking about the sails.
After some research I could buy online or a give making a set myself.
For the past 10 years my wife sewing machine has been sitting in a cupboard , when I asked if it works , her answer was NO it's a heap of junk.
A new challenge :
Two hours later after a clean and a spot of oil its running but as yet not sewing .
A little forward thinking"|
I have purchased a roll of thread and some new gizmos the thread is wound on also 1/2 mt of cloth.
Now for the first question :
Re the fabric online info about sail made the recommendation is a fabric called 'Dacron"
I was told the material I have purchased is the same as Dacron but at a better price.
Any tips on using this type of cloth . It feels very slippery like a dog on lino Col
