C-Scow

Sail Design

In 2012 UK Sailmakers set out to develop a new brand of C-Scow sail. With the input from veteran C-Scow sailor, John Porter, we spent time evaluating existing sail shapes on the water and in the loft. We used our years of sailmaking knowledge and computer analysis to develop our shapes. We built two full scale test sails to evaluate on the water and on the computer with our accumeasure program. The time and effort paid off with our first sail winning the first two regattas it raced in dominating fashion.

T1+

Wind range 0-20

Our Light/Medium mainsail is the go to mainsail for most crews. It has excellent power yet the unique ability to flatten out in higher winds…perhaps easier than any other design. This sail has great power out of the tacks but its ability to flatten out well allows you to outpoint the competition when needed. PRICE: $2,195

T2X

Wind range 0-5/ 15+

This sail thrives in the windier conditions but can be used on the extreme light airs of 0-4. The sail is flatter with more open leech than the T1+. For additional durability and longevity we use a heavier fabric throughout the sail. For lighter crews that will use this most of the time we can use our lighter standard cloth. PRICE: $2,215

UK Sailmakers offers you:

  • Accurate design
  • Easy trimming
  • First quality cloth and hardware

Tuning Guide

T1+ 

The T1+ is a sail that works well from 0-16 MPH. The sail is very powerful and accelerates well when footing (leeward telltale just fluttering) after building speed, the sail points very well while maintaining great speed. With practice, you will be able to accelerate past the boats next to you then pinch them off. Below is a suggested set of tuning numbers for various settings on the boat. These have worked well for many of our customers, but every boat is slightly different. If your boat is from 2013 or newer, the rake numbers should be 1” shorter at all settings to account for the reduced stretch with the new forestay attachment. In all conditions, your boat should balance with very slight pull on your tiller. If you can’t hold the tiller extension with two fingers, continue to tweak the rake and board height until the boat balances. A balanced boat is a fast boat. Mast rotation is controlled by mainsheet block position on the boom. Moving the blocks forward reduces rotation. A good general setting is to allow for 45 degrees of rotation. 

Jackstays control mast bend. Traditional knowledge says that in everything but light air, the looser the jackstays, the faster you go. Check your warranty paperwork to understand the implications of going beyond recommended settings. Older masts have 1/8” jackstays. A safe, fast setting is to set these at 44” for most conditions with two sailors aboard and 40” with 3 on board. With the thicker 5/32” Jackstays, we have been fast with the jackstays at 52” but are very careful not to overload the mast. This setting is fast, but does run the risk of bending or breaking the mast, especially in waves. 46” with two on board and 42” with 3 on board is the “warranty spec” and will make you plenty fast. Under 5mph, 36” has been a good setting for both thicknesses of jackstay. UK Sailmakers offers these numbers as examples and will bear no responsibility for masts damaged using these tuning numbers.

T2X 

The T2X is a sail that works well above 13 mph. The sail is flatter than the T1+ but also likes to build speed footing, then point. The sail points very well while maintaining great speed. It is not uncommon to build to over 7 knots of boatspeed in a puff before pointing high. Below is a suggested set of tuning numbers for various settings on the boat. These have worked well for many of our customers, but every boat is slightly different. If your boat is from 2013 or newer, the rake numbers should be 1” shorter at all settings to account for the reduced stretch with the new forestay attachment. In all conditions, your boat should balance with very slight pull on your tiller. If you can’t hold the tiller extension with two fingers, continue to tweak the rake and board height until the boat balances. A balanced boat is a fast boat. 

In big waves, consider running the outhaul a little looser than normal. Also, move your blocks forward on the boom to reduce mast rotation and reduce load on the mast in waves.
