20 ways to boost Lug rig and lug sail performance! Rigging and Tuning.

Thought I would try to put everything I have about the balance lug rig, standing lug rigs, their setup and tuning for sailing dinghies, sailing canoes and small yachts on one page. Lug rig setups (either cheap or sophisticated), tyes of ropes, tuning guides, controlling sail twist and more

1/ Basic lug setup and tuning with some budget for fancy fittings

Goat Island Skiff as example of setting up a lug rig.

2/ Basic lug setup and tuning with no budget for fittings – Oz Goose as example

Low cost with no sacrifice of sailing performance – this is the method we use for racing our fleet of Geese in the Philippines. Maybe you don’t want to race, but if the boat works better when cruising – why not!

3/ Two Lug Sail Rigging Setup Videos showing ropes and positions

These two videos are for setting up an Oz Goose using the kit we supply in the Philippines for the 10 boat builds we do here. So the rope usuage is different from your boat. But the basic methods are identical particularly the knot types and the required tensions.

4/ Leach Ribbon positions for a lugsail

I had to play around … also an invaluable sailing for speed tuning tip. Have to avoid the wake from the mast and yard interaction

Fitting leach ribbons and telltales to a lugsail – where works?


5/ Sailing methods have changed – if you luff up in a gust then you are making boat control more difficult.

Sailing methods have changed a lot in the last decade or so. It has been found that difficulties controlling a sailboat in stronger winds has been made more difficult by traditional teaching of boat handling.

Now learning to sail is much easier to explain and learn …

… and strong wind sailing is easier for everyone.

Our Free Sailing lessons are here – the most important ones with the largest changes are the upwind sailing methods.


6/ What  is that crease in my lugsail? Diagonal crease – a common lug setup problem

This is a common tuning question for lug rigs with an incredibly easy answer.

Simple to fix the crease from bottom end of the yard to the back of the boom on lugsails.

7/ Where can I get a not too expensive lugsail or other sail?


Did you realise that Lugs and Lateens are close relatives?

the deepest reef possible for a balance lug turns it into a lateen rig.

One more reef will do it in this photo. So some aspects relevant to Lugs are also relevant to Lateens.

10/ The single biggest performance improvement on any sailboat rig is controlling sail twist

Controlling sail twist is almost the story of sailboat performance and tuning for the last  hundred years. A hundred years ago the balance lug was the predominate small boat performance rig where there was choice. Because it controls sail twist and the gaff rig doesn’t.

Here are various methods from simple to complicated to control sail twist on lugsails. You do need some twist BTW, just not unconstrained twist.

With the bermudan rig the need for controlling twist for best performance led to the boom vang, the full width traveller, vang sheeting.

But that is expensive … which is why we use the balance lug rig setup for modest cost but still very good performance.

A big contribution from Brian Pearson or “Keyhavenpotterer” on this page.

11/ Which side does the boom go on when going downwind and dynamic control of heel with the sheet on unstayed lug, gaff and lateen rigs – By the Lee is useful!

Sailing by the Lee in not tricky – but is useful! It is a well known high level method in racing. But it adds to the stability and control of our small (and much bigger) boats with unstayed masts. There’s a video of us changing the heel of the boat when running just by moving the sheet in and out.

12/ Lug Rig setup from 100 years of development in the Lymington Scow Class Dinghy – 100 years of using a balance lug rig in weekly races.

You learn one or two things by sailing against other boats for 100 years.

We met Brian Pearson and nothing was the same about our lug rig tuning and setup advice after that … well a great deal was changed.

13/ Reefing Faster Revolution using Fixed size Loops on small boats, Two Videos

Throw away all the blocks and pulleys and metres of line and reef or unreef in half the time. Lazyjacks not necessary

Drop loop over front of boom, snap other loop on leach into carabiner and rehoist and tension sail – and you can still adjust the outhaul normally!

14/ Reefing a balance lug sail – tie tingles or use one line for the tidy up.

The time comes when there is too much sail. Main reefing lines are in at back and front of sail … do you really want to tie up 5 to 10 ties in the body of the sail?

Individual ties around the boom or bottom of the sail might be too fiddly – what about one line that does the lot?

Shamelessly stolen setup from the big racing yachts.

15/ Boom or no boom on your sailboat … is the sacrifice worth it?

Boom or no boom best for my lug sail boat?

A no boom rig is very portable and easy to set up and stow. There are some sacrifices in performance and you never see a drop in performance from normal lugs on most boats when a boom is added.


16/ Club racing a lug rig 1 – a Goat Island Skiff with conventional sailboats – PY number

A test that has been done. A midweek racing series gave us the beginning of a baseline for the GIS … about equal with a Laser Radial or OK Dinghy. A lot more tuning and practice to come as more and more boats get built.

17/ Club Racing a Lug Rig 2 – Beth Sailing canoe

Even more extreme … sailing a balance lug canoe YAWL against conventional sloop rigged dinghies – PY number

Who said a mizzen was a really big handicap?

Who said a balance lug wouldn’t perform with modern sailing dinghies?

19/ How fast can a trad rig go 1?  … Arab Dhow coming unstuck Video

Arab Dhows start racing by hoisting their sails when the gun goes. They are also big and immensely fast.

And as you will see … boomless sails have rather high sheeting loads :)

20/ How fast can a trad rig go 2? 12ft Oz Goose in a ridiculous wind

On this  day racing was cancelled and we had the rescue boats out. There’s a plot there showing a boatspeed of 18 knots for two seconds on one of my speed runs recorded by GPS. Lake is tideless freshwater in the Philippines.

Video of a massive nosedive without problems on the same day… because the rig is easy to handle and the hull has no vices. A normal dinghy would spear off to left or right – note the goose has the tiller centralised.

Oz Goose at speed - around 11 knots. Record is 13.8 knots - storer boat plans

21/ Low cost Lug rig – putting 10 Oz Geese on the water for the price of importing one Laser Radial with spares.

We have learned a lot about keeping costs down in developing nations to boost participation rates in sailing. Yep .. that is  10 to 20 people on the water for the cost of a Laser .. or  30 for training all with good feel even in light winds.

Building sailing dinghy fleets in developing nations on a shoestring budget to increase participation in competitive sailing.

23/ Rant on lugs and mizzens and stuff

What is the point of a mizzen? They have been declared to not be efficient, but as you can see above a sailing canoe yawl rigged can race against club Laser Radials.

  1. Mr Storer
    I am very interested in your article describing the rigging set up for the Goat Island Skiff. I am trying to apply your ideas to setting up my Passagemaker, particularly the halyard arrangement. I note that you suggest position a block on the midpoint of the yard to run the halliard through. Will this not bring the yard too far forward of the mast when it is hauled up? The Passagemaker instructions specify a hole for the halyard much further forward than the midpoint and looking at photos of the Skiff the attachment does not seem to be midpoint. I realise that this is not one of your designs but I would be very grateful for you comments.

    • Hi Eain,

      No problem … the information will work with most small boat balance and standing lugs.

      For where the halyard comes down to the yard we used to use a block. Now we just put three turns of 4mm spectra with polyester outer around the yard and put the halyard through two of them (the third one pulls tight around the yard and prevents the whole shebang from slipping around much.

      We find 45 to 50 percent works with most sails. But be methodical with the position, and the position of the tack of the sail relative to the mast until the sail is where the designer intended it to be in the drawings.

      Halyard setup for lug rig that minimises fittings.

      The advantages of this method is after the halyard goes through the loops it goes forward to the front of the yard BUT GOES ON THE OPPOSITE SIDE OF THE MAST to the yard and then ties off at the front of the yard.

      No holes in the middle of the yard and no second line needed to prevent the yard moving forward or back and no parrel balls needed to stop binding as releasing the halyard loosens the tension holding the mast tightly to the yard. Zero chance of binding.

      When the sail is dropped the yard comes down horizontal too rather than flips with the tip down.

      The good thing about both methods is that they are both done in just rope – doesn’t cost anything – so try. For our method we put two holes in the front end of the yard – first one for the halyard tie off, second one for the throat lashing.

      Hope this helps.

      MIK
