But we really need more info about where you want to use the boat, how many on board, budget, open cockpit camping or is there a desire for a cabin, and so on and on. Check out Craigslist for used WW Potters, Catalinas, Buccaneers and other 16-22' fiberglass boats for a basis of comparison to what you can build in wood.
Have a look at boats like Bolgers Otter 11, with polytarp sails, second hand fittings and exterior bonded fir plywood glued with construction adhesives, nailed and screwed with galvanised fastenings and painted with plastic paint you might make the budget. I looked in to the Weekender myself but ultimately decided to go a different route, but it's up to you.
My first and most major concern was their decision to use a full length keel with no ballast instead of a standard setup with a centerboard. My second concern was the absence of a self-bailing cockpit, which isn't that big of a deal for a small trailer sailer, but is nice to have since it doesn't involve a whole lot of work or effort to work in to a plan.
I'm looking along similar lines as you actually, and am considering the Glen-L 17 or Minuet, or the Selway-Fisher Sandgrouse myself. Either way, I think you'll find that the decision itself is the hardest part, I know I have. How could he possibly build the Glen-L or S-F boats, all up with sails & trailer, for under $2k?? As above, he'll either have to buy a used glass boat, or build a bare-bones economy boat per John Welsford's suggestion. Remember Mr Niles is now talking about using his limited funds to building the hull first, and add sails at some later time, possibly a season or two down the road, who knows? They drew gasps of admiration as they arrived in Waterford over the past four days, but nothing compared with the sight of 45 Tall Ships sailing together out of the quays and along the River Suir yesterday.The majestic vessels left to cheers from the hordes of spectators who had descended on the city for the festival. Their course was expected to take them around the west coast to Greenock, Scotland, yesterday, but bad weather forced them to head eastwards and sail along the Celtic Sea.The Russian ship Mir, a visitor toA  Waterford in 2005 when the city was last a host port, was an early leader. The westerly course would have taken the ships an estimated five days to reach Greenock, while the first of the vessels is expected to get there by Wednesday.A cruise from Greenock to Lerwick in Shetland will follow, while the second race will be from Lerwick to Stavanger, in Norway.

On any given sunny or wickedly stormy day, when we step our feet onto our sailboards and with our booms in our grasp, sheet in, and the wind fills our sails, we start to move.
That may be all that we want to know about a sail: it’s there, it’s beautiful and it’s giving us freedom.
The sail’s leading edge obviously aerodynamically important, but not so obvious is what’s happening at the back of the sail above the boom on the trailing edge (called the leech).
Looking down the leech, one can see that it is either a straight line from clew to head, or perhaps convex with a smooth arc, or maybe concave, or any combination of the above. Sail-makers are keenly aware of how their sails are twisting because of these two facts: well designed twist will de-power a sail in order to make it more controllable in gusts and strong winds, and secondly, twist can prevent the upper part of the sail from stalling.
Since the angle of the wind widens as you go up the sail, it stands to reason that the maximum twist should be located at the top of the sail. The section of the sail that is twisted still has the airflow attached, but produces less aerodynamic lift force. David Ezzy developed the Endo-Batten for windsurfing sails in 1998 to achieve a symmetrical profile and help batten rotation. A sail shaped with excess luff curve has more luff curve than the curve of the mast after being rigged.
The endobatten produces a perfectly symmetrical sail and saves all the weight of the batten pockets.
There is another added benefit in the non-rotational system, and that is that we are less reliant on mast stiffness, since our profile is not coming so much from excess luff curve, but more from profiled panels. The Ezzy cam is also a sail driven cam, but it fits any mast diameter from a modern reduced diameter to a twenty year old standard diameter mast.
With the proper rigging technique our camber induced sails rig almost as quickly as one without cams. The Ezzy Sails Spectra® X-Film is the strongest and lightest windsurfing sailcloth in the world. The luff experiences the most static load in a rigged sail, so the material needs resist stretch and have good needle hold strength.
Leech has high load when the sail is in use, so the material must be very low stretch along the edge of the leech.
The tack and foot areas are under constant abuse by harness hooks and board noses, so this area needs a very impact resistant cloth. The upper middle part of the sail has less directional loading and can therefore be made from a lighter weight cloth, but still needs to be impact resistant.
Our tack is reinforced with 12 layers of spectra X-film and two layers of polypropylene webbing. A lot of sail companies are cutting corners by using thin, un-sewn sticky-back cloth on the leech. We have worked very hard over the past few years to lighten our sails, while still retaining their strength.
Inventions like the Endobatten have taken almost a pound of the sail’s weight because we no longer need all of the layers to make batten pockets. Our Specter X-Film has allowed us to use the strength and lightness of Spectra to make a lightweight bulletproof cloth. We are obsessed with the desire to make the absolutely best quality windsurfing sails in the world. This project is an introductory investigation of buoyancy and the shape of different boats for different purposes.
With an adult’s help cut different hull shapes from balsa wood, cardboard, or Styrofoam trays.

Experiment with each to see how quickly they can move across the water when given a little push. Once you have completed your exploration of different hull shapes experiment by adding keels.
If you are interested in experimenting even more with your boats you could investigate rudders and tillers.
You may want to take photographs as you complete your experiments to use for your science fair poster or presentation.

I have seen that you can bould one for under $2000 though that is probibly the cost of the hull construction, but I was counting on that. If you wanted to go small, the Glen-L Minuet would be a reasonable build, but I think the cabin might not meet your requirements.
Further looking around has shown this decision to be the right choice, as it seems the Weekender is not highly regarded in most builder and boating forums out there, except the ones directly affiliated with the boat.
Those two from Glen-L are about all they offer that fit what you're looking for, but Selway-Fisher has a lot of options that could fit with what you're looking for and the designs seem quite good.
You might want to look at simple dories that could be rowed now, fitted for sail later, and take either a tent cabin or small cuddy.
It is built on a simple framework which becomes an integral part of the boat’s structure. Before long, the last craft was a dot on the horizon.The a€?parade of saila€™ took the ships out of the Waterford Estuary to Dunmore East, where their gruelling race began. The third and final race will bring the fleet to Halmstad, Sweden in the first week in August. By clicking Confirm bid you commit to buy this item from the seller if you are the winning bidder. Import charges previously quoted are subject to change if you increase you maximum bid amount. But high-performance sail-makers look at other things going on in the sail that make or break our enjoyment of that watery ride. The amount of sail area that projects backwards from the straight line from the head to the clew (see diagram) is called roach. This difference comes from a wind gradient that exists and causes wind strength to be less nearer the surface of the water and stronger higher up.
If the maximum twist is below the top of the sail, either the sail will stall in the head, or it will lose power from the twist being too low. Stall means the flow is not attached and that part of the sail is producing no aerodynamic lift. A sail with more luff curve will require more downhaul tension and have a more rigid profile.
Wave and freestyle sails tend to have less foot curve so that the foot stays out of the water during moves. This forms a cavity next to the mast, which, in the case of a full batten sail, becomes batten rotation. One problem with traditional full batten sails is that they are asymmetrical because the battens all sit on the same side of the sail.
This is a rotational sail and represents a sail that has most of the profile built in via excess luff curve shaping method.
That means, when you tension the batten, the sail shape comes from the batten taper plus the profile in the seam. When the sail is unloaded, we set the batten behind the mast in about the same place the traditional rotational sail type batten would be when loaded. Nowadays all cams are sail driven, which means the batten is in a closed pocket and does not connect directly to the mast. Our sleeves are made up of two vertical curved pieces without any horizontal seams that could come apart.
This simulates a grommet and is perfect for people that want to use either a pulley hook or the North ratchet extension. We counter this in two ways: 1) we sew a plastic bead along the edge of the foot and 2) we use a special chafe resistant tape on each side of the foot. We have no hard edges, or abrupt ending of layers that could cause the clew to blow out.  A light clew makes a huge difference in the sailing weight of the sail. The goal is that the student will learn through their own experimentation the reason boats are shaped and engineered the way they are and gain scientific knowledge around a real-world concept. As for the Weekender, I was intrigued by the design as well at first, but had some concerns about the design that I addressed in an e-mail to Stevensons, which I'll outline here. Even on those boards though, there seems to be a lot of talk about people righting their Weekenders after a capsize. The Lynx 14 on the site links to a site of a guy who built one (it's just a small 14 footer) and sailed it across the north sea to Holland and back again, and there's a link to his site where you can read his tale. One vessel that was docked on the north quays was SA?rlandet, a Norwegian ship built in 1927, which won in 2003.
If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. When the sail is full of wind, this roach and trailing edge of the sail can “open-up” or “twist” away from the front of the sail.
So, the bottom of the sail experiences more apparent wind, which comes from the direction the board is travelling.
Slalom and race sails have more foot curve so that they can be raked back to close the gap between the sail and the board. The problem with sails shaped with ONLY this method is that in strong winds, the mast bends more, which removes the shape from the front of the sail. Panel shaping when used in conjunction with excess luff shaping produces a more stable sail profile.
Flipped one way and the battens push against the firms sail body, pushed the other way, the battens raise off the sail as they push against the soft pocket material.

We have eliminated the batten pocket and instead place the batten in the center of a horizontal profile seam. When unloaded or in light wind the lower and middle battens of a rotational sail rotate hard around the mast.
Now combine this with the Endo-batten profile in the sail body and you have a much more stable profile. The main difference in rigging is that our sails take quite a bit of positive outhaul tension. The pockets come in ten different lengths, which adjust the space inside the sleeve, keeping the sleeve tight at the camber. High wind is also better because the camber stops the sail profile from shifting in big gusts. For people that are more concerned with maneuverability and easy jibing, no-cam is the way to go.
Our X-Film weighs about the same as standard 5-mil monofilm, yet it is more than 1,000 times stronger in tear strength.
The tack pulleys are made completely with 316 stainless steel and are CNC’d to precision with an inner bushing to turn around.
Some of the parts of the boat that play a role in the way the boat moves are the hull and keel. Science Education, teaches and develops curriculum for Pre-Kindergarten through 6th grade science, in addition to helping to coordinate her schoolas annual Science Day bringing the student body together to present their work in science and participate in a school wide science project. I was hoping they could provide me with some details as to why it works and why they went that route. The lack of a centerboard and ballast on a boat that small and light just doesn't seem like a good idea, regardless of what their site says.
I'm leaning towards the Fisher Sandgrouse myself, as it just seems like a more stable and manageable boat compared to the 17. I was primarily answering his questions about the Weekender, and giving options of similar designs that are out there.
As we discussed above, the maximum twist should be at the top of the sail; therefore it stands that the maximum roach also be at the top of the sail.
This can be seen in many sails when they have high downhaul, the batten fronts want to “s” and also the foot batten wants to only set in one direction (pushing against the pocket). Since they do not have much, if any, profile in the sail body they assume a very flat and draft forward profile- not a desirable profile for light air.
Our sails are the exact opposite of most other sails that have very little shape in the panels and most of the shape coming from the excess luff curve. This kind of system is normally extremely mast diameter specific, which means you are limited to the particular mast designed for that sail.
By experimenting with the shape and materials used to make these parts of the boat we can determine which shape is best for what purpose, and understand science concepts such as buoyancy and water displacement.
Create a chart like the one you used in your hull experiments to keep track of your tests and observations. Sarah has experience teaching science at museums, nature centers, and environmental education centers in addition to her work as a classroom teacher.
The number of instances I've found of people capsizing those boats certainly supports that theory.
We won before.a€™GardaA­ estimated 200,000 spectators had turned out on Saturday alone, bringing the official total to an estimated 500,00. If instead, we were to look up at our sails, we’d see the foiling of the cloth as it fills with wind. The location of the roach up the leech will also dictate where the maximum twist will occur. If the top of the sail were set with no twist the flow of air would not stay attached to the surface of the sail and the flow would stop or “stall which would then have detrimental effects over the entire sail. Horizontal shaping is usually under the battens and is a better shaping method than vertical shaping because it controls the shape from luff to leech.
Then as the rotational sail gets in more wind, the battens get pulled from beside the mast to behind the mast. In light air the batten is behind the mast and there is more profile back in the panels – good light air shape. This becomes a real problem if your mast diameter does not match the mast designed for the sail. As with the North American fishing dories, these boats can be stacked one on top of the other, and cheap materials could be used in their construction. Adding to this list of variables, a flatter sail profile will twist more than a fuller profiled sail. The result is more draft in the back of the sail – not a desirable shape for high wind.
Then as the wind increases the batten moves more beside the mast and this has the effect of moving the draft a bit further forward – good high wind profile. This is especially a problem if your sail was designed on a standard diameter mast and you want to use a reduced diameter mast. The plans also show details of a sailing rig with rudder and daggerboard and a 5'6" beam version. Outfit and trim will take the most time depending on the level of finish desired by the owner. It goes from a flat draft forward profile in light air to a deeper draft back profile in stronger wind. This translates into a sail that jerks you forward in light gusty wind and then gets backhand pressure in the in strong puffs.
It would be better to start off in light wind with more profile in the sail, then as the wind increases to have the draft not get any deeper and not move back.
