Members of Clontarf Yacht Club are building an IDRA14. Below is the most recent update from the club.
As we head into this next bank holiday, we’re over half way along with the planking - we have put the 7th plank into place on the starboard side a while ago, while also doing last minute work to have our own boats ready to sail in the IDRA 14 Northern Championships in Rostrevor at the weekend.
Riveting and planking is going on steadily. We’ve been using the wooden laths or ribbons to help set out the spacing for each plank but after a recent visit from Martin O’Toole and Jim Boylan to the boat shed, we’re considering removing the remaining laths now and completing the planking using a spiling method. This should also work better for the remaining planks, as there is not so much steaming involved from here onwards.
The process of spiling involves using a spile-board, a piece of plywood similar to a plank, but lighter! The spile-board is placed on the boat where the next plank will be positioned. The lightness of the board allows it to be easily pressed into position providing a more accurate shape. It particularly facilitates getting the planks to hug the moulds on their way around the tumblehome zone of the hull. Marks are made on the board and transferred onto the actual plank, so that it can be used again and again.
Meanwhile, in early April, Nigel Young from North Sails Ireland came up from Cork to measure the sails of IDRA14/160, as 166 will be fitted out with new sails from North Sails. He spent about 2 hours on a Friday night, with Ronan and Lorraine, taking a series of measurements –
1. Taking note of the official class sail measurements,
2. Measuring an existing set of sails, and the spinnaker while laid out on the rig,
3. Finally, with an IDRA14 fully rigged, but lying on her side, he measured the sails with rig tension for tension on Light, Medium and Heavy Airs.
The measurements were sent to the North Sails Design Department for input into their system – we hope to have a computer design sent to us shortly.
Nigel’s father was a boat builder, building a Dayboat, a wooden dinghy not unlike the 14’s, that Nigel helped build and sail. Nigel has shown great interest in the project and had time after taking the measurements, to look at our progress to date.
The rig – Mast, Boom and Rigging – arrived to the shed in March from SUPERSPARS, who have been very generous, giving a great discount to help with the project. The rig has been safely stored, waiting its turn – a while to go yet!
