Sails and Sailplan

Sailmakers, I am looking for price and delivery on the following:

Cl-11/Gull Dinghy    (Ian Proctor design)  

1    Mainsail

• luff 14'8", foot 6.9"   please specify roach/battens
• one row reef points at approximately 28" from tack, rising to 31" at clew, 
• cunningham cringle.
• Loose footed

2    Jib

•  8' 6.5", 7' 4.5", 4'2"  See photos for luff attachment as built  3 plastic hanks.
• Can a larger jib be made and still utilize the sheet leads?

3    Spinnaker 

•  10'2" luffs, 11' foot.  or nearest stock size if it exists,

Miscellaneous information:

Measured dimensions of existing sails, grommet to grommet are:

Main:   14'6", 16'2", 6'9"    No reef points, rope foot and luff, three battens)

Jib:  8' 6.5", 7' 4.5", 4'2"  See photos for luff attachment as built  3 plastic hanks.

Spinnaker 

 10'2" luffs, 11' foot.  or nearest stock size if it exists,

See photos below for details.

Questions:

Weight of cloth?

I see a larger jib specified for the gull spirit - does this wourk with the standard jib sheet leads or is this sail particular to that model

In practice is a window required in the jib?

Does anyone actually use the spinnaker for recreational sailing?  Is it worth while?

Good enough for me!  Thanks Roger

In Canada the CL 11 has not received the development and attention that the CL16 has however these are both raced and enjoyed more extensively in the UK.   (As Gull and Wayfarer respectively.)   In the UK, the gull is raced as a class, with detailed specifications, including sails and rigging.

While Ingrid will not require class compliance, the rules are useful, and it seems clear that the CL-11 is a Gull in sailplan.

The Gull class rules state:

Spinnaker

(c) Spinnakers shall be three-cornered and symmetrical about a line joining the head to the centre of the foot
	(d) The measurements shall be according to the sail plan, with the sail dry and laid on a flat surface. Measurements at the corners shall be taken to the centres of cringles, which shall not exceed 1¼ " (32) diameter. Each measurement shall be taken with the sail pulled just taut enough along the line of measurement to eliminate all creases across the line of measurement
	(e) Each luff AB shall be measured individually and shall not exceed 10' 2" (3099)
	(f) The centre measurement AC shall not exceed 11' 0½" (3366)
	(g) The width measurements shall be taken with the sail folded in half along the centreline and laid on a flat surface with both halves coinciding. Points D, F, H shall be marked on the centre fold at 2' 7" (787) and 7' 9" (2362) from the centre of the head cringle and points E, G, I shall be marked on the luffs at 2' 7" (787), 5' 2" (1575), and 7' 9" (2362) from the centre of the head cringle. The half width of the sail between D and E shall not exceed 2' 2" (660) nor be less than 3' 0" (914), and between H and I it shall not exceed 4' 0" (1219). The half width of the foot BC, from the centre fold to the centre of the tack or clew cringles shall not exceed 3' 10" (1168)

Main

[luff]   Position of coloured band (3) on mast, lower edge 15' 1½" (4610) above upper edge of (1). No part of mainsail is to extend above the lower edge of (3) when racing

(b) The measurement of the leech along a straight line from the centre of the head cringle to the centre of the clue cringle shall not exceed 16' 3" (4953) in Bermuda sails.

(e) The mainsail foot shall be attached to the boom for its entire length between tack and clew cringles

Boom (Bermuda or Gunter rig)
	(a) Of wood or metal, but if of wood to be solid, except for groove for sail bolt rope
	(b) Position of coloured band (5) with inner edge 7' 2" (2184) from aft side of mast, when assembled on gooseneck
	(c) The clew of the mainsail is not to extend beyond the inner edge of coloured band (5)

Jib

(c) The maximum dimensions of the measured between centres of the eyes at tack, head and clew shall be:

(i) Small jib,  ( Original Class jib)

Luff 8' 7" (2616), Foot 4' 2" (1270), Leech 7' 3" (2210)

 

(ii) Large jib ,( Modification with the Gull Spirit building adopted by the class)

Luff 8' 7" (2616), Foot 4' 2" (1270), Leech 7' 11" (2210)

spin per class rules

Spin size 10'2" luffs, 11' foot.  

Looks to me like the Sailplan is identical, and that maybe the main could have a longer luff.  Need to measure that to be sure. Good news in that the foot and luff are roped, and I would like to convert the foot to loose-footed, with the ability to control draft, and there appears to be space to do this.

Also interesting is the possibility of a spinnaker.  I note the larger jib requires a different lead, this may be specific to the spirit model as indicated.

Spin size 10'2" luffs, 11' foot.
