how long are the spinnaker sheets needed to be? And what size?

Sailed hard in a 15 knot wind for the first time this past weekend.

Had a blast- Definaltey not like the Thistle-

Thanks-

Is there somewhere on the website that has the suggested lengths of all the running rigging?

Thanks-

There is a recent thread on halyards, it includes the mandatory discussion about going to all rope halyards. You have not ask your questions very well, it is not your fault. We need to know if your halyards are led back to the cockpit or are still at the mast. What size halyards you should buy depends on your deck hardware. Is the Spinny an Asym or Sym? The devil is in the details... your not dealing with a one design boat anymore so you get to design and execute what you want with your boat. We will be happy to tell you what we have done but you need to decide what will make you happy when you write the check.

An Oklahoma and Kansas fleet of Thistles has met at our lake in the past, magnificent machines.

Thanks Frank- I have the haylard and topping lift already in place. The haylard is not run to the cockpit but I think there is enough to do so. My spinaker is Sym. I am wanting to know what size line and how long of line is needed for the guy and sheet. I am going to rig an after guy as well. Any suggestions?

How are you planning on launching? From the Bow, From the Rail or from the cabin?

From the bow you want enough line to go from bow to stern, through a twing/tweaker with enough tail to trim from wherever you find it most effective and comfortable. Usually in moderatea air this is from the shrouds but sometimes from the front of the cockpit. This also depends on where your cans are. I'd call this 40 feet. Launching from the bow means your bowman is forward a lot longer while rigging. Obviously not desired if racing, especially in lighter winds.

From the rail you need what is listed above and also have a guy and sheet that can run around the forestay to roughly the shrouds with the same amount of tail needed. Probably 55 feet.

Launching from the cabin is a bit difficult if you are sailing with anything bigger than a 135 foresail, but still doable. Maybe an extra 5 feet.

IMO these measurements are a bit generous.

Hi Tate!

I use 5/16" line for the sheet and the guy that I use most of the time (for heavy air I occasionally use a 3/8 line for the guy). They are each about 55 ft long with lightweight snap shackles eyespliced on the sail ends, with disks up against the shackles so the shackles do not get jammed in the ends of the spinnaker pole. I have a set of 1/4" for lighter air with no snap shackles and lighter weight disks, and also use parachute cord with no shackles or disks in drifing conditions with my 3/4oz chute.

We rig the sheets thru blocks about 2 ft forward of the aft end of the outside tracks. In heavy air I also use 1/4" twinging lines with the sheets each passing thru lightweight roller bearing blocks. The twingling lines themselves are led thru blocks on the outside rail located just aft of the upper shrouds to pull the sheet down and forward (that really helps to stabilize the chute and also seems to really help when close reaching with the Star Cut. I also use a reaching strut when close reaching with the star cut, and it really help control the pole better when its forward near the forestay.

I launch from the bow or the lee rail/lifeline depending on the conditions, angle of the wind for launching, and number of crew on board.

I used to sail a Thistle also, way back in my college days. We sailed with the Delta Sailing club (part of DIYRA) on Arkabutla Reservoir in north Mississippii just south of Memphis TN, and we sailed the "regatta circuit" all over the mid-south. Thistles are FUN boats!!!

Cheers!

Chuck

Para cord on a 3/4 ounce chute for light air? 3/4 is a pretty heavy fabric.

Well, everything is relative I suppose. If I had a 1/2 oz chute, I would use it for drifters, but alas, I do not. The 3/4oz is a rather full radial head, and my other chute is a 1.5 oz triradial (see picture from a helo that I posted). So, the 3/4 oz is quite lightweight compared to it!!

Actually, the 3/4oz with the parachute cord sheets lifts fine if there are any zephers at all. Amazing how much even the 1/4 oz sheets weigh......

Cheers!
