Hi Roy and Jaydee, what about using piano wire to make a wishbone instead of a jib-boom, similar to the rig between the masts on a schooner? It would be less noticeable than a jib-boom and allow the foot of the heads'le to take a nice curve.

Hello Jerry,
Both of the Jibs shown have a very stiff plastic rod fitted into the bottoms of the sails.
Almost "hidden",they are to stop the sail from curling in the wind.
The problem arises from the sheeting points being in the centre of the hull, instead of the real life positions.
They sould be sheeted from the very edge of the deck, pulling the sails down and keeping them nearly flat.
Big problem - - - there is no Crew!, the Crew would move the sheeting points when the boat tacked.
No way to do this with Rc !! - - - OR, keeping things looking Scale.

Hello,

Just got an invite to the  "J Class day", hosted by the Nottingham Model Boat Club, at Colwick Country Park, Mile End Road, Nottingham. NG4 2DW on the 27th of July 2014.

 I went to the event last year, a really good day out!, very good lake, very nice people - - and lots of Sailing !!.
Looking forward to meeting up with all the folk I met last time and seeing their fabulous boats !.

Will be taking my J Class, Endeavour and am hoping to leave some grooves in the water.

John.  :-)) :-)) :-))

Hello,

Got a busy weekend coming up, next Saturday I will be at the Daresbury Steam Fair, near Warrington.
As a member of the Runcorn Boat Club I will be showing the J Class and my One Metre boat - - display only.
We will have a small Pool for the smaller boats , the children also get to sail some special boats - - they love it.

Then, on Sunday I will be at the Kirklees Club Open Day - - - SAILING !!!!.
Lovely Lake and People, always enjoy being there.

Looking forward to both Events, hope the weather holds up, got my waterproofs if not !.

JayDee, if the foot of the jib is rising, how about installing a downhaul, similar to the installation on a mainsail. The downhaul would run from the foot of the jibstay out to your plastic "boom". This jib downhaul would not have the down-force power of a mainsail downhaul due to the acute angle between  the jibstay and white plastic boom (vs the almost a right angle between mast&boom). But, it should reduce lifting of the boom.

For a more elaborate fix, you could run the downhaul to a semi-circular track, rather than the foot of the jibstay. This would give a better angle for the downhaul, at the expense of possibly needing fiddly adjustment and tuning.

Your ships are beautiful, so nice to see the photos :-)

Hello Brooks,

I have moved the Jib pivot aft about 4 inches, it used to be at the fore end of the Jib.
This gives enough down force to give a much better set to the sail.
The sail now is much better than before.
Thank you for your very kind comments.

Nice fix, simple and effective :-)

If you were to put a crane under the tack of the jib (i.e. under the boom tip extending fore of the new jibstay attachment), you'd eliminate any rise at all. The crane would have to be curved to match the arc of the boom, of course. I'd make the crane a little lower than the boom tip, just to be sure not to introduce drag when the boom needs to switch sides in a tack.

Also, if you are still having problems with wrinkles in your mainsail - The photos I saw suggest that the sail might benefit from a Cunningham. I don't know if mylar would work with a Cunningham, though. But when you make your silk sails, adding a grommet an inch or two above the tack would allow you to add a Cunningham if you wanted.

 Hello Brooks,

There are many other modifications that could be done to the boat to improve its performance, but,                     they would not be to Scale !.

My boat already has a non Scale Keel and Rudder, I wish to keep things as they are.

The Keel and Rudder are not seen while sailing, altering the Rig is in full view all the time.
The boats performance is very good with things as they are now, to improve it would need major changes.

For me, "Scale" wins every time !!!.

Hello,

Got another trip out, on Sunday 27th this month, sailing at the J Class Day at Nottingham !!.
Have given the boat a bit of spit and polish! - - bound to bash her into something and scratch things !.
The weather seems to have settled down, hope it keeps fine for the Event.

 Hello,

The weather at Nottingham J Class sailing Day was very, very good.
So was the Lake, the Wind and best of all, the Company !!

Loads of laughing and chatting, good food too.
A real good day out.

Sailed my J Class in the company of lots of the Nottingham ones, they are fantastic boats, able to cope with large changes of weather with ease.

Their build quality is very good, Laser cut parts, and the Glass fibre Hulls have to be seen to be believed.
They make my Hull look decidedly dodgy !!!!.

Thanks to all who attended - - - Roll on next Year !!

@JayDee:

That sounds like a great day out, would love to see some photos or video if there is any available. We don't see this style of boat in my part of the world...

Thanks JayDee!

Having them next to the car gives an indication jus how big these boats are! Surely you did not squeeze all three in that car????

Hello mrpenguin,

Yes, all three boats, more Hulls and lots and lots of other things were all in the owners car.
My own boat at 6 feet long fits easily into an Estate car, some times with camping gear, tent etc
.
If, it has to fit in - - it WILL !!!.

Hi Mr. Penguin Forrester is a nice car, I had a breakdown with my car when visiting a friend and car was in garage etc for repair. (A faulty replacement exhaust baffles had collapsed)  My friend had a Forrester and lent it to me for 3 days to get home etc.  It convinced me what sort of car I wanted next, and a few months later I bought a Honda CRV, Had it for the last 13 years!  Great car, takes my yachts etc.

Another cheer for Subaru! :-)

For years in the 1970's, they were the best-selling Japanese brand in the New England states. If your typical winter weather consists of 3' of snow, changing to 6 hours of rain, followed by 6 hours of freezing rain, which transitions into a 72-hour deep-freeze with howling northerlies, then you can't go wrong!

Hello,

 The Bridlington Open Weekend is almost upon us!, I have just finished checking the J Class, it will be a "testing" time at the event - - done some mods to the Keel.

Because of the bad weather the boat has not been sailed since the mods, so, fingers crossed that all will be OK !.

Been having problems with the boat rounding up into the wind when hit by a gust, I have added more area to the rear of the keel to help with the balance.
To keep the Scale appearance the mast could not be moved, so the keel had to be altered!.
The keel is non scale anyway, so altering it was the easiest thing to do.
Just need some nice sunny, windy weather to test her.

Can you slack the jibsheet to reduce weather helm in a gust?
