Hi All,
I am looking at buying a second hand spinnaker for cruising and there are some advertised locally.

Does anyone know the approximate luff and foot dimensions of the one design spinnaker. I know the area is 36.3 m2 but those advertised simply have luff and foot measurements listed, so it would be useful to know.

Thanks. James

For any Class dimension, please refer to the class rules and drawings, which are found here >> https://ifboat.se/baten/klassregel/klassregel .

The pages can be translated to most common language using the built in translator (click on the flag on the right upper corner )

In this case:

Spinnaker Luff and Leach : max 8,27 metres
Spinnaker Foot and Half Width : max 4,55 metres

The measurements are taken as shown in the World Sailing's Equipment Rules of Sailing, but for approxiamte values, just use a 10 metre tape ruler and measure from corner to corner and across from midpoint to midpoint of leech and luff.

The area of the sail is not considered to be a Class measurement . This mainly dependent on that one have to agree to a formula of calculation, and different formulas give different values.
