Northwind’s are a simple boat to sail for the beginner and further below we outline the boats features and accessories in detail. As with most TS’s they are older mix of craft, but like this one, you can still find a well maintained and loved one.

About the Boat

The Northwind hull has an interesting history being first built as a Southern Cross, then change of ownership they became a Northwind 7 when then on sold again to become a Sonata 7….  All in all whichever of the three “makes” you own, they are all great 7m boats and very capable sailing boats!

One great feature is that they have a relatively flat bottom which helps if you want to beach them or the tide drops out from under you that the boats don’t list over too much. With the keel up the hull only draws approx. 25cm! Another feature is that the pop top allows great head room for tall folk and opens up the cabin to allow more ventilation and light inside and best of all the boat can be sailed whilst the pop top is up.

If the wind drops out, the boat can be powered by the Tohatsu 8Hp long shaft motor. This has a 25l fuel tank offering plenty of range if needed and the 8Hp will generate a good turn of speed.

The sail wardrobe is comprehensive including:
  • Main sail with a reef point
  • 1 storm jib
  • 1 genoa
  • 2 spinnakers and a spinnaker pole
  • 2 older Jibs in working condition

Most of the sailing has been with a main and the genoa and all are in workable condition. The keel is electrically motorised via a cable for ease of pressing a button. The cabin as pictured is comfortable and well laid out with the creature comforts one wants for an overnighter and the galley is well equipped with lighting, a stove, sink with approx. 60l freshwater storage aboard and plenty of storage is offered for the rations and crockery.
