All respect to the supporters of the Farr 3.7. 

Just thought though, if the Farr is an easy trap boat for UK lightweights would it have worked to put a wire on a Phantom?

Not a great deal heavier boat, a little longer but I see some 3.7ers feel the need for a rudder gantry anyway and a boat that is well known and already around in numbers in the UK.

Lighter, less sail and a higher boom than a Contender.

I like the general concept of the Blaze with it's multiple rigs, the Aero and of course before them both Laser.

Seems sense to me to widen the family of a boat rather creating lots of tiny niches.

The litle Farr is a much more sophisticated shape than a Phantom though. And there's more to being a lightweights (or heavyweights) boat than just adding leverage or rag..

Jim, how do you define sophisticated in dinghy design? The Farr to me looks like a nicely designed plywood box, same as many of the nicely designed plywood boxes of the UK, Phantom included. Some of the design compromises are different, for sure, but why does that add sophistication?

And anyway... would a frankenboat actually make a viable class? I don't think so. Imagine the 'Forum Storm' of negativeness, both on here and on the Phantom Class site if I'd tried to do that to an established class. I'm not into damaging and cannibalising. One of the most attractive things about the Farr 3.7 is it already has a class constitution, rule set and organising body set up. It's established and has been for 40 years. In the UK we are just tapping into all of that experience, and broadening the base. I'm staggered that the Farr 3.7 hasn't made it here before my time. It's a fantastic boat and would really improve the sailing landscape in the UK.

If you can get a close look at one have a look at the curvature in the panels below the chine and how its distributed.

The Phantom ( and similarly shaped Mirror14/Marauder ) were originally designed for stitch and glue construction, so the hull shape is constrained by the way the ply sheets bent when pulled together.
The Europe is another hull shape determined by the bend of the original ply construction.

Well yes Jack you are correct in all you say, however on balance that is more about the politics of sailing and classes than design.

I am just asking a question on a "Dinghy Development" forum.

I do salute anyones enthusiasm for a Class that they feel an affinity to, I know, I'm an ethnic minority in the dinghy world myself.

Why is it, just because we're light, everyone seems to think we have to have short length boats?

I seriously looked at that Farr, it should be right up my street, but 370? Really? I wouldn't look at a race board that short, even 380 is pushing it.

And that picture in Y&Y a 'new' boat for us to enjoy here in the 21st century, made of wood and looking like just about every other 1970's design, it really is 'back to the future' back here in good old 1985, even the Rooster Streaker looks more modern I'd sooner put a trap on that.

If you looked a little further, say on Butler Boats Facebook page, you might see that there is a composite mould being made iGRF.

Size has a relationship to weight as well as a relationship to being able to make one in your garage. But the biggest relationship that size has is to is FUN. Shorter boats are more lively and therefore more FUN to sail. The first two relationships also add to the FUN triangle as moving light boats around is more FUN and certainly building one yourself is a lot of FUN....

...So you see it isn't that light people (& kids) have to have short boats, it's just that light people ( &kids) like to have FUN.

Like your spirit Jack Beer , I'm all for FUN. 

For what it's worth. I've nothing against wood either, good stuff selected by people who know their trade weight to stiffness there are boats made of a lot worse materials.

Yep it's a lot of fun going off the line beside some 4,20 Laser stuffing it as high as he can.

Larking about FUN? Get a kite and kite board, 3 dimensional fun, up and down as well as across.

I note they feature a carbon rig though having had a look on the website, so the day may well yet dawn that they build a composite and feature a carbon rig.

Do they offer self assembly pre cut kits? I would have thought that would be a useful item to market.

But if you did that to a phantom it would become a medium weights boat which is already serviced by the contender so what would be the point other than the higher boom, which isn't that much different once you take the rig on a phantom anyway

Could do Tick, but, she's a bit too heavy to lose sail area and power though, I suspect a Contender with less wouldn't go in light or heavy.

That's as clear as mud and as useful as a chocolate fire guard.

Is there a box of bits, with a retail price tag and instructions? Then next question (note the buying signal) how much?

Don't you just love trying to buy stuff from dinghyists, it's so simple.

iGRF if you look here  http://www.uk3-7class.org/index.html" rel="nofollow - http://www.uk3-7class.org/index.html  you will see a very large Banner Ad that you can click. And this will take you to a page where you can buy your plans. You can even pay via PayPal. You can choose to have the CNC files which you can use to cut your wood which you purchase from Robbins. All of this information is available on the same website. The plans contain everything you need to make your dinghy. Plus we have provided Blog's of all the people that have built there's so far so you can avoid there mistakes. Or understand more easily the build process.

Or if you wish a nice New Zealand company can partially make up the CNC cut wooden parts for you and post them all the way around the world. In fact he will even sell you a hull that is finished and waiting for paint. But it wood. Sorry.

You can see our simpleton website below where you can find the big button to press:

I'd challenge that last part- it would still go well in light winds (perching) and th wire would be there for when hiking looks like too much effort.

And you could whack a bigger sail on it- it's not a Phantom anymore after all.

You'd need to change the rig anyway as the trap would change the bend characteristics of the mast (or snap it), so you may as well bung on a 12 or 13 SqM sail and be done with it.

Or design a new boat, long and slim, specially for lightweights who find waterline length and speed fun, rather than shouty FUN!!!!!!!!! with far too many exclamation marks. Something less extreme than the IC, without racks but with a trapeze and a smallish sail coupled with an easily driven hull with decent non trap performance. Maybe RS should produce it, call it the Twix or something.

Or have Hobie had than name already?

Nope, it needs to be sold Ikea Style... Boat in a Box, easy assembly everything you need to make this exciting new boat, £999.99.

It's a dumbed down world we live in, we want it and we want it now, don't mind spending a weekend putting it together, nothing more I'm afraid.

That Butler Boats should prefabricate it then pack it all up in a box, you might sell a few more.

Jim C. You tried to help me get my head around the geometry of this before.
We are talking hard on the wind of course.
What is the difference in loads on the mast between say a 100kg 2 metre bloke hiking hard all the way out and say a 50 kg twiglet wiring flat off the gunwales? Wiring off a combined shroud attachment point as in my Contender. Forgive the inexactitude of my numbers, just trying to represent a similar righting moment.

I think that it's probably easier to get a boat sorted for lightweights than heavyweights. After all to get something that's genuinely exciting for a bigger person means that it's going to have to be very windy and therefore difficult to sail. Lightweights have it much easier, bung abut more sail up and a force two is good

So are all the parts pre-painted in your scenario, GRF?

I don't think the 3.7 would work for this (too complex a shape) but I'm sure it would be possible to make a very simple boat to be put together in a weekend (with primed panels to reduce the amount of painting) but the compromises in design for the construction over the performance would be pretty big. The method of slotting the panels together has been around for 40 years or more, but normally there are a lot of parts, so it takes time. Best bet would probably be a scow shape boat - could even be totally rectangular, vertical sided - all the shape in the flat bottom panel, built upside down off a flat deck. Would go great on a reach.

I usually get screws left over.

I'm serious, that Farr thing could be supplied as a box of bits, you'd get the plans, all the bits cut out, the ply necessary to build it all in a box the size of the biggest bit of ply, why not? Then there might have to be a separate box with the rig bits in it, two part mast obviously. Nice Instructional DvD on how to put it all together.

I thought that is roughly how it can be supplied? It'll take far longer than a weekend to build, though, and take some basic woodworking skills - the end product is rather more complex than a wardrobe.

The Flyer appears to have rather misunderstood what makes a skiff type boat tick, and with its failure (which was also predictable when you look at what people buying fast boats want, often - to get an adrinaline rush, not to spend weeks in a garage) so went the company.

I think Grumph is looking for something even more simple. Trouble is it also has to be waterproof and to sail well, things which an Ikea wardrobe doesn't have to do.

The Snark, sold in supermarkets in the USA in times gone by is probably the only sailing dinghy to have the accessibility GRF is looking for, and I don't think he would be impressed by the performance.

Why self build hull for a DIY boat? The easy thing is to bash out laminate hulls and supply them with all the other gubbins in kit form. There is a model boat class called the 'bottle boat'. I believe the hull is made of two coke bottles stuck together.....could there be a full sized equivalent?

You probably could, but imagine the size of the bottles....possibly would be filled with beer, so either have a couple of weeks on the lash before building or find your local drunk to help you out

Not just Mirrors, there were kits for building a Miracle (which we all know is iGRFs true sailing-object-of-desire) Phantoms and many others. Or with some more skills, build a GP14, Ent, Solo or many more

Not sure most have the tools and skills even for building a Mirror these days. Probably some 'elf-n' safety nonsense about using resin too.

And of course the proven performance variances within a class enabled by the relatively large building tolerances necessitated by all this home building are proof as to why a polars-based dinghy rating system will not work

There's plenty of very good Phantoms kicking around the <£3k price point these days (thank you D-One owners).... adding a wire would not make a sprightly little boat like a Farr, but it would certainly liven-up the experience if hiking your balls off doesn't quite appeal.

fundamentally 

time poor, cash (or credit ) rich - you go out and buy one ready-to-sail

time rich , cash poor- depends if you have the skills,  if you have the skills to make a boat measure to modern rules you are likely  to want to  have control over  materials  specification and fitting choice within the rules  ( which  would further pump up the ppirce of the thiese mythicla 'boat in a box packs)

if you don't have the skills even with pre cut panels and simplified  construction methods you'd still have issues making it measure  and if the boat doesn't measure it's money flushed down the drain

Bell went to the wall as they could not make money from the model being proposed , I dread to think what  the courier/ delivery firms would charge ot deliver a 'boat in a box ' kit  even with a multi piece mast ... it would be too heavy / large for the  parcle boys  which puts it into the realms of the  commercial carriers who aren't set up for  residential multi dropping ...  where a set of plans  can be  sent by  royal mail parcels / your choice of document courier / as computer files to  the local large format printer / work CAD monkey ...

Bell probably went to the wall because all they were offering was dross.

That Little Farr 3.7 is not exactly dross, nor is the Hadron although having studied some of the builds it is trying to stay within the class rules of the Ark.

I wonder if a more modern self assembly pre pack could be constructed, it would remove the biggest cost factor, labour, maybe I shall consider this in my winter project..

There are also a lot of 2ndhand boats around, so if cash poor, that is a cheaper route to ownership than a kit, especially as a mast and sails are so expensive these days.

You only build a kit boat because you want to do carpentry, not because you want to go sailing.

I was thinking.....masts are complicated technical things these days, engineered for bend characteristics, stiffness and all sorts of other stuff. What you need is a long thin blank that can be shaped and machined. So why not go back to wood? I have seen hollow wooden masts made by sticking two hollowed out halves together. You could rout a slot for the bolt rope and keep planing bits off to make it flex where you want it to. It could also have a section like a wing mast. At the end you could skin it in carbon for protection.

Someone who shall remain nameless from the UK Cherub fleet did than when competing in Mirrors in the 80's. It was a surprisingly light and stiff gaff (wooden ;-) ) section and measured perfectly.

Don't ask, very rocky ownership?

Trouble with wood spars is that they get rather heavy by modern standards

Not sure there are many people around with the skills to "tune" a wooden mast these days - certainly not me - and possibly not too many who could successfully glue the 2 halves of a pre made one together. And not cheap, either.

It would be an interesting exercise...I suppose that one would decide on a rough? shape, then laminate the two halves up in strips, glue them together, rout the slot, fit the sail, lay the whole lot on its side (see Ian Bruce Byte C2 video), and plane/sand until it achieved the desired performance.  What wood to use? Yew probably. I was never talking of cutting the branches off a tree trunk, a la Nelson!

So, one goes to all this trouble, spends a fortune, fits the mast with it's aerofoil section and different bend characteristics fore and aft, port and starboard...and it's crap! Back to the wood yard boys.....No, not interesting at all. What would be interesting is how it would affect my PY........yawn.

Bamboo obviously.. Typical dinghyists never even got the wood right all these years..

The British Moth had a bamboo mast in the 30's. And single wire shrouds. People were brave back then...

Masts are traditionally Sitka Spruce.

I would have thought something straight grained like poplar.. They use it for snowboards.

Whilst we're on the subject of wood, why is it that the term Gaboon is used for the Ply?

I think it would be hard to machine nice squared off strips from bamboo. Spruce would be ok on a mast made in one piece, poplar is less flexible than yew...but much cheaper. I did think of Rowan since I can see about ten of them from the kitchen window. Ash is probably too stiff but mountain ash (Rowan) looks more flexible. 

Yes, why is Gaboon called Gaboon?

Gaboon is a tropical West African hardwood tree which is valued for its timber and was used in the manufacture of ply typically for the exterior faces.

So not only do 'they' the wood botherers, infest our lakes, abuse our young and new people, perpetuate antiquity, they are also responsible for African de forestation.

I did wonder.

Bamboo masts were made from a complete piece of very large bamboo - a bit like the scaffolding that was (is?) used in the far east.

Sitka spruce has been used to make 2 piece (joined up the middle) masts for 100's of years.

Personally, I think the invention of the ali mast was one of the great steps forward in mast construction. Love wooden boats (where wood is still right up there in terms of strength to weight, but wooden masts don't do anything for me at all (apart from looking at other people's and thinking that it looks pretty).

Ive got to say that the details of wooden masts is far more interesting than PY
