Calling all Senior owners, builders and dreamers!

Post by Bethem »

Hi, I’m Mat Gravener your YM Senior rep.
I have just finished the season using my newly built Senior and have had some great sailing on the Norfolk Broads.
There is a section on the restorers and builders page and a six page article has been published in the November/December issue of Watercraft Magazine.
I purchased a hull which had sat in a chaps garage for fifteen years and using the plans built the centre plate version, all went together well and she was a lovely project.
I kept a photographic and materials used records so anyone who wants any information regarding this super design trailer sailer please get in touch.
Regards
Mat

Hi Mat
Many thanks for starting this thread. And thank you for the excellent article in Watercraft!
I am in the process of building a Senior (I 'bit the bullet' and epoxied the hull together yesterday). Thinking ahead I was particularly interested in your approach to setting the gunter rig and how to reef effectively. I would very much appreciate the associated measurements. ie length of your spars if not standard from the drawings, the positioning of the fittings on them and the height of your 2 reefs from the mainsail tack.
Oh, and what make are the fittings?
Sorry for all the questions!

Hi Keith,
Thank you for your comments regarding the Watercraft magazine article.
The complete Gunter rig came off a Senior which was being broken up, and all the spars are as per the plans. The only slight discrepancy I could see is the position of the pulley on the gaff, mine is positioned 58 inches from the throat end.
Starting with the mast, a sail track is fitted about a foot above the base and stops just shy of the halyard pulley at the top.
On the gaff throat is fitted a dinghy style gooseneck which suits the mast track. Further along is a strap round the gaff with a pulley.
A stainless sail slide goes in the mast track first and the halyard is made fast to this, then the gaff is slid on, halyard goes though gaff pulley then up to mast sheave.
The sail, although fitted with ten eyelets along the luff I only fitted sail slides in five of these to cut down friction.
In practice as you haul on halyard the gaff throat stays down as the rest of the gaff rises and lays parallel to the mast, then it all goes up.
I will measure the two reef positions and sort out photos of the various parts this weekend.
There are no makers name on the parts which is a nuisance as I would like to find another gooseneck as mine works but looks quite worn.
Cheers Mat

Hi Keith,
Two rows of reef points, first row 24 inches above boom, second set 24 inches above first set.
Halyard pulley on gaff 57.5 inches from throat.
Photos to follow.
Your Senior is looking good, please keep us updated on progress.
Cheers Mat

Many thanks Mat
All copied to my files for use when I make my spars.
I am making steady progress with my build and have now epoxied the hull panels. Once filled and faired I will sheath the hull rather than taping the seams.
All the best
Keith

Hi Mat
Although I am building a centre board version of the Senior I am planning to get a couple of small steel bilge keels made up so that she can comfortably take the ground when needed. The boats keel would still take the weight of the boat and the bilge keels would support her laterally at such times. Each one should weigh circa 15kg and so they will provide a little more stability to the boat as well. The only down side I have thought of is that they will move the centre of effort aft fractionally, but from what I read that shouldn't pose too much of an issue.
Can you or any other Senior owners think of any problems with such an approach (I have reinforced inside the hull and each would be bolted through one of the floors also). The pics show the plywood mock up that will go to the steel fabricator.
All the best
Keith
