E-Sails Tri-Radial Cruising Chutes are a super easy-to-use design, their flying shape is optimised for a broad range of reaching angles, so they will greatly enhance your downwind sailing pleasure and boat speed. They can be hoisted from a Launch Bag like a spinnaker – or they can be used with a Snuffer (both items are available separately, and through this site).
E-Sails Tri-Radial Cruising Chutes are available in a range of standard sizes that will suit many yacht and rig sizes. They are available as either Single or Two colour options, choose colour preference when ordering.
Colours available for either the Main body colour or the Stripe are: Red, White, Blue, Grey and Yellow.
They are Tri-Radial in Layout, meaning they have horizontal panels across the centre and the corner panels all Radiate inwards, so that the sheet loads are running directly along the fibres, unlike the more basic Spinnaker layouts, such as Cross-Cut and Radial Head designs. (When the fibres aren’t loaded along their threads, permanent fabric shape distortion can occur).
Material is 1.5oz Ripstop Nylon – which is an ideal weight for most cruising yachts and for most wind conditions.
The Sails feature Leech and Foot tapes and Pressed Rings on Tack, Clew and Head.
The sail is supplied in a Nylon Bag, and they are suitable for use with Snuffers.
CHOOSING THE SIZE:
We recommend that you choose a Cruising Chute with a Luff Length that is equal (or about 98%) of your measured (SFL) distance. i.e. From your Spinnaker Halyard’s maximum Hoist position, down to the Cruising Chute’s Tack attachment point (ordinarily this will be about the same as your yacht’s quoted Forestay Length (FL). If you plan to use a Snuffer or a Furler, then deduct another 0.5m from SFL to allow room.
MEASURING THE SFL: This distance can be measured most easily with a surveyor’s tape measure hoisted on the Spinnaker Halyard. Alternatively, you can hoist a stretchless rope, mark the length carefully and measure that. The Cruising Chute will have a curved Luff profile and so there will be a room in the Luff to tension it.
CALCULATING THE SFL: The (SFL) is the Hypotenuse of yacht’s given I & J measurement (see diagram below)
Hypotenuse = The square root of I squared + J squared
e.g. therefore with I – 8.9m, J – 2.3m
Hyp(SFL) = the square root of (8.9 x 8.9) + (2.3 x 2.3)
Hyp(SFL) = the square root of (79.21) + (5.29)
Hyp(SFL) = the square root of (84.5)
Hyp(SFL) = 9.19m
So, choose a SAIL LUFF of approx. 9.0m (or 8.5m with a Snuffer).
(For peace of mind, the Luff Length will nearly always be very close to the I dimension).
