Spinnaker size

Inlägg av Mummi Troll »

Hello IF owners,

What is the official Spinnaker size for IF Boat?
Can I use a H-Boat (H-vene) 36 m2 Spinnaker to start with?

What is the Spinnaker Boom recommended length?

Accordning to official boat data the spinnaker area is 36 m2.
Accordning to the swedish SRS-rule the area is 31.4 m2.

Check the measurements with the class rule, page 24-25! I suppose an H-Boat spinnaker is of similar size. I have not checked, though.
In the class rule you will also find the spinnaker pole length, maximum 2530 mm.

Hei Johan,
Thanks for the fast answer!
This is a good news, as I can find for this summer here in Finland a H-Boat spinnaker, which is also 36m2.
I wish you great wind!

The size of the spinnaker (and also other sails) are mostly estimations and thus dependent of the formula or estimation used.

Calculated for SRS, the spinnaker areas for IF-boat and H-boat are found to be very close (31,36 sqm versus 31,63 sqm). Anyhow, for the H-boat the spinnaker leech lengths are shorter but the foot and half widhts are larger.

The figure 36 sqm (the same for IF and H-boat) is information given by sailmakers based on how much cloth is being used to make a sail.
