Plastimo tips & tricks

Chainplates or turnbuckle ?

  • Most sailing boats are equipped with chainplates to fasten the forestay to the stem fitting. Chainplates come with several holes which facilitates the adjustment of the standing rigging. The use of chainplates also allows to position the tack point as low as possible.
  • The turnbuckle version allows for more accurate rigging adjustments. However, the tack point will have to be positionned slightly higher depending on the turnbuckle size.

Which jib reefing size for my boat ?

Plastimo proposes 3 models to fit all sailboats from 4 to 11 metres. While the boat length is important, you must also consider the forestay diameter and the headsail size. For example, in the case of a 6-metre boat, the 406 model will offer the best compromise. However, if the headsail size is much larger than the maximum sail area recommended, selecting a 609 model is a better option.
