Members of Clontarf Yacht Club are building an IDRA14. Below is the most recent update from the club.

Just a short update to keep you posted on what we’ve been at in July and August – with a rare and amazing summer, and an abundance of sailing in Mediterranean conditions, it’s no surprise we didn’t hide ourselves away in the boatshed to work on 14/166. With the IDRA 14 Nationals in Lough Ree in mid-August, when we weren’t sailing, our focus was more on getting our own boats in order ready to compete. It was a great event in Lough Ree with 17 boats competing over 3 days. Our thanks to our hosts, Lough Ree Sailing Club, who gave us a great welcome and put on an exciting and enjoyable race event. It is a joy to see the IDRA14’s performing to their best and showing what exciting boats they can be in the right conditions.

While work did slow down somewhat in favour of sailing, quite a lot of detailed work has been carried out on the keel and the hog, this is the type of detail that doesn't look much but believe us when we say it takes time, patience and a lot of consultation. 

The bevel, which was planed in the keel to take the garboard, runs from flat to almost 90 degrees at the stem, the hog has to correspond with this bevel. Bevel is good in both cases. The hog bevel has to correspond with the keel bevel in order to create a rebate for the garboard. We plan to have the core skeleton, - hog/keel, stem and transom and stations assembled by mid September. Both the Stem and Transom Knees were laminated using teak and oak strips and are now ready to fit.

Ruairi Grimes, a member of Rush sailing club, who is studying Naval Architecture in Southampton has offered to transfer the IDRA14 plans onto CAD for us. As well as the original drawings and the newer plastic boat drawings, he will be creating new drawings for us.

Ruairi has worked on Pat O’Neill’s boat 14/15 so is very familiar with our IDRA14.

So far he has created a drawing of the centre board casing as the original centreboard case was 
designed for a much longer centreboard which had a lead infill before the trapeze was introduced. 

Ruairi will design the new timber centreboard case to fit the existing centreboard and has also 
produced drawings of the current centreboard we use. 

Many thanks to Ruairi for his help and enthusiasm.

We will be installing a Go-pro camera, located permanently in the work shed so we can capture the progress in time lapse so nothing is missed, this will be very important once we start assembling the Keel, Hog, Stem, Stern and Stations.

Once this is in place it will be time to call in the official measurer from the class. More on this later.

The build has a mention in the Yard News Section of “ Classic Boat” (the magazine for the world’s most beautiful boats) in the September edition – great to appear alongside so many other prestigious boat building projects. We have established CY&BC as an official boat building yard.

Superspars, Hampshire, UK will provide the mast and rigging for the new boat. They manufacture Rigging for an international range of Dinghys such as the GP14, International 14 and flying 15, they are an approved supplier to the IDRA14 class. A number of the existing fleet are using the Superspar mast and rigging already. They will supply Mast, Boom, Spreaders, Trapeze Rig and all running rigging and sheets.

3rd of July 2013

After the excitement of the keel laying ceremony, and some beautiful summer evenings when sailing came before boat-building (on those evenings, it’s very clear why boat building used to be a predominantly winter pastime!), attention turned to the stem.

We marked-out the stem including the halving-joint and the rebates to receive the planking. This was a slow and complex process done in stages over a number of days. From roughly sawn, we used a Festool OF 1400 router to remove material quickly. Planing and chiselling was followed by further marking-out and more work by hand before achieving a ‘working’ stem. The final shaping and permanent jointing of the bottom of the stem and forward section of the keel, can only take place when we plumb and level the horse and can ensure the keel and stem are inline. 

We have started to shape and cut the hog to size, as it will need very sharp angles for the planks to fit into it. We used a Festool TS 75 plunge saw and CTL 26 integrated dust extraction to achieve this. We also bevelled the keel to receive the garboard as it bends from almost horizontal aft, to vertical at the stem!

A closer look at the keel reveals a natural defect hidden in the middle of the keel. Again discussions take place as to the best way to strengthen this, and it is decided to put a stopper on each side of the fault to strengthen it, before patching it up with thin strips of wood and epoxy where the fault has been removed.

In addition to this, the slot in the keel has to be further cut – the plans that we have for the boat don’t show the exact measurement for the slot, although we can estimate where it should be, by measuring from the stem. The original design of the boat had a longer slot, to fit the centreboard, which had lead on it. We looked at the slot on one of the later wooden boats to be built, IDRA 14/30, Chloe, which has a much shorter slot and a centreboard of a similar size to the plastic boats and to the IDRA14’s which were built after it was decided to drop the weights from the centreboard in the sixties (thank you to Ian Sargent, class historian for the information on IDRA14 history and when the weights were dropped from the centreboard).

As a side project, Michael makes a number of wooden clamps, which we will use when we are putting the planks on. They are modelled from an original clamp provided by Martin.

Most recently we have been working on the knee, which will connect the stem to the keel. Laminates were cut and we’ll be able to show progress on this next month.
The ISA and IWAI have mentioned our project in their recent news bulletins and we’re delighted to be able to get the word out about the project. We did receive contact from Dave Foley, who worked on the AnCo boat building project in Skibbereen, as a result of the mention we got on RTE’s Seascapes programmes. One of the things we still don’t have and someone out there may have, is the Schedule of Wood, which our plans refer to. We are writing up details of additional measurements, schedule of wood and other details, which may be of use to the next person who builds an IDRA14 but if you find any additional IDRA14 plans lying around, do let us know about

6th June 2013

Members of Clontarf Yacht Club have kicked off a project to build an IDRA14. Ronan Melling, Tom Lonergan, Paddy O'Kelly, Donal Heney and Marc Gleeson are at the forefront of the project. Michael McGuigan who works with Festool power tools has recently joined too.

Below is the most recent update from the club.

Now into May, things are starting to take shape nicely.  We started off the month, sizing and sanding the 6 stations and the new transom (yes new transom, made a booboo on the first one!)  Luckily Tristan Stones boatyard sent plenty of Mahogany to us. The new Transom was cut, sized and sanded all ready for positioning on the keel.  Transom is perfect now!

Paul McNally (from Sutton Dinghy club, who rebuilt IDRA 14 number 6 and launched last year ) kindly dropped down the set of stations he made up for his rebuild  and we were delighted to confirm(!) to him that he got it right, they are the exact same size as ours - sorry Paul couldn't resist that one!

We are reaching a critical stage where the keel will be shaped and planed to be laid on the stock so all measurements and the position must be 100% accurate.

The Stock, on which one of the new mermaids from Rush sailing club was built last year, has now been sized, shaped  and planed to accommodate IDRA 14, no 166.

The positions for the stations, centreboard pin, stem and transom are marked on the stock. Checked, checked again and rechecked and once more for good measure.

All the sized and planed Spruce planks and the mahogany combings and sheer strake are stored ready to use.

The Workshop is now looking like there is some semblance of order, our mammy's would be proud of us, everything has a place and there is a place for everything!

Our plans are now displayed on our work board; all we need to do is follow them properly!!

A date has been picked for the traditional ceremony for the laying of the Keel  - Ian Sargent our class historian has picked a date  and the pressure picks up to ensure the keel will be ready for Friday 24th May.....the official day for the ceremony….. so discovering that the Stock is 35mm shorter than expected on Thursday the 16th  Is not at first a welcome surprise. All part of the fun though, nothing like a bit of pressure to focus the mind.

There was a little head scratching and hum humming until a very old method to resolve the matter was used – out came the hammers and in no time the decision was made.  5 minutes of hammering (dismantling) and we were ready to build a new top section to our stock – easy! (unfortunately no video footage or photos of this moment!)

A new top section to take the shape of 166 is measured, cut and sanded and fixed onto the stock. The keel is measured, cut, shaped and planed.The keel is ready to bend onto the stock in time for the laying down ceremony. Phew!!

Friday 24th May arrives and is a great success. Over 90 people arrive to the workshop for the keel laying at Clontarf Yacht & Boat Club. Shane Kennedy – son of IDRA 14 Class designer, George O'Brien Kennedy, -  formally signs off the keel laying, while others cover the keel in messages wishing us well with 14/166.  The celebrations continue in the club, with speeches by Ronan Melling, Shane Kennedy, Ian Sargent (class historian) and an address by Maurice Wilson, Club Commodore.

On the same evening a special presentation was made to Julie Ascoop and Heather Keenan, in recognition of being the first female crew to win an IDRA 14 National Championship. Dermot Bremner (former class secretary and one of the group who introduced the GRP IDRA14’s) made the presentation on behalf of the class to Julie and Heather. We hope to see 14/16 competing for the national title some day!!

The reception in the club lounge lasted into the wee hours of Saturday morning.  Now the hard work starts – keep up to date with our progress on our Facebook page - IDRA14 New Build.

If anyone has photos from the Keel laying night, please send them on to us – we’d love to see them and hear any stories from the night.
