At one time we had a small fleet of Panache yachts, another free plan, and we used to compete with those.  I still have one, needs a bit of TLC at the moment.

Hi Mr Zippy


Thanks for all the pointers and information you have given, the Starlet kit does not come with a plan and includes only the shaped pieces of laser cut wood. The Star baby kit does come with a plan but at 96.00.


Being as I enjoy the build process I have ordered a Star Baby plan (as that may suit my transportation better) and apart from a sail winch/servo and sail material I think I have the materials needed already in my possession.


It will not be a quick build as I tend to be a slow builder and no doubt will need further help from the forum when I eventually get started.


Regards


Adrian

Sorry but just noticed that on reply#25, my photo of my Panache came out OK but the verbal comments didn't. Not to worry , not overly important!

Hi all
excuse me for jumping on this thread, fancy building a yacht, never done one before and Starlet seems a good place to start, using the Belair kit as a base, though to add a bit of complication, Tony's gaff rig looks  a bit different and something I would like to emulate, or is this too ambitious for a first build, am I barking up the right tree here or just barking mad.

Hi I have converted a sailing boat from bermuda to gaff.  Things you need to know.
Centre of lateral resistace of the hull.
How to calculate the area of a sail'
How to calculate the centre (by area) of each sail.
How to bring the different centres together as one.
Where to put the sails on the hull and by inference where the mast goes.
A simple rule of thumb is the c of a should be 4 % ahead of the c l r  measured at the waterline.

There is a bit of backward thinking.  If you have a known working bermuda rig set of sails then work out the centre of area and this point should be the place where a new set of sails have their c o a.
it is all simple stuff if you can do very basic maths and remember basic geometry construction then you can do it.  Lots of paper and long rulers.

I have a personal rule of thumb for model yachts, not competitive, that if you weigh the keel lead multiply this by the distance to the waterline, I use pounds and inches.  Remember this number.

A 20 mph wind will give 1 pound pressure on 144 square inches of sail.  Treating 1 square foot of sail as equal to 1 pound and multiply this by the distance the c o a is above the waterline.  This number should equal the other one.

You may well find that the area of a bermuda set of sails is not sufficient to create a gaff rig suite of sails then increase it til it looks right using the above calculation.
Remember the c o e of the gaff sails will be lower so there is less heeling moment.

If you can do all these things then sails are at your disposal to use as you will.
Good luck,
Roy

Hi Roy


appreciate the effort you have put into your reply, but that information is way above my head, but learning and working out this kind of information is what is attracting me to sail, and of course learning to sail.

Hi the thing is it sn't above your head!  area of a triangle = half the base times the height.  All sails breakdown into triangles.  You join two centres of triangles with a line and use proportion of areas to see where the centre point is.  You can also do this with card from the cornflakes packet, cut the shape out and balance it on a point and that is the c of e.

You get the centre of lateral resistance of a hull by pushing it sideways with your finger until it does not go one way or the other.
You just do it in order and it all comes out!
Follow it and see. But it may take a little time.
Good luck and have a go
