J Class sailing
« on: March 13, 2011, 07:44:41 PM »

Hello,

Finally made it to the Lake today after the major refit to my J Class, Endeavour.
New Cabins, fully planked Deck, new sails and a scale paint job too !.
The weather was very kind, light breezes with a few gusts, but sunny and quite warm.

Rigged up and lugged the boat to the water, weighs 40 lbs now, and away she went.
Almost sailed hands off, just a touch of rudder trim and that was it !!.
Had a real good afternoon of sailing, a good two hours.
Boat was bone dry inside when back on its stand and I was smiling a LOT !.

Been a whole lot of hard work, but this sail made it all worth it.

Hello Andrew,

Oh I do hope so, we have no trip to Germany this year, so God willing, I will be there.
The J Class will sail there OK, having a shorter  Keel than the Schooner.

Nice to hear from you,  what have you been doing ??.

Hello,
 
I have a friend who is "in the know" with woods, so I took his advice to choose a wood which would look like Pine, which was used on the real Endeavour.
The grain on Pine was too big and didn't look scale on the deck, the wood he chose was Ash, in a Veneer 0.6 mm thick.

The Deck planks are 4.5 mm wide  and were Varnished with Yacht Varnish, the margin planks and the King planks are Obechi wood.
I am an Engineer, and for me, working with wood is a punishment!, it splits, breaks and is not at all like working with metal!!.
After a very long time and many, many planks I finally got the job done - - - and I like it !!.

Hello,

During the test sail on Sunday, the Quad sail - - the outer Jib, was showing signs of creasing during the gusty parts of the sailing.
Today I have been moving the sheeting points on the Quad, to see if this creasing could be rectified.

On the real boat the sheets for the Quad were taken well aft, two sheets either side of the boat,
Doing this on a model would mean that the Quad sail would not be able to Tack, the Crew moves the sheets to move the sail.
Models have NO Crew !!.

Having the sail set on the wrong side during a Tack would not look right , so more work needs to be done.

Good thinking Martin, I see a rush ( or is that a rash) of these developing.  :}

 Hello,

Had quite a struggle getting the Quad sail to set correctly.
The Quad sail is not a triangle like the Jib, the Quad is shaped like this "  /_____\  " with the tops joined.
So the sheeting on the top and bottom has to be just right for the sail to set correctly.

I have a alloy tube, an old Mast, which I fastened to a 3 foot piece of wood, to make a very large "L", which I then used as the front of a "Dummy boat", and set the Quad and the Jib on it.

I could then stand in the wind with the sails set as they were on the boat, and adjust the sails very easily, no weighty boat to turn from side to side - - very nice !!.
A couple of my neighbours saw me doing this!,- - thought I was cracking up !.

Well worth it, walking the frame into the wind gave me the effect of a gust of wind, going the other way gave me calm conditions.
A DIY Wind Tunnel !!!.

Hello,

Removed the Bowsies which were setting the sails during the test sailings and fitted the two winches.
The Quad and the Jib are controlled by a Hitec lever arm winch, a 815 BB.
The main is controlled by a RMG 380EH winch.
The Rudder servo is a 1/4 scale Futaba one.
Power is supplied by a 6 volt 4Ah Nicad.

The radio hatch seemed rather big when building the boat, but it very quickly filled up.
All the Gear is on the large side !!.
Waitng for some nice weather to do some more testing.
John.

John, there's this approach to controlling a loose-footed outer jib - it allows tacking and decent sail set on everything but a run. Any use?

Hello Andy,

Many thanks for the suggestion, I already had that thread saved, good idea!.
There are other variations on that theme, not tried any YET !!.

Sailed the boat today with the two winches working, very, very nice to sail.
Got a few points to tidy up, but nothing serious, it all worked very well.
In fact it was good enough to leave well alone !!.

I might just enjoy sailing for a while, after all the time and effort.
BUT !!.

John.  :-)

Hello,

After yet another "test" sail at the Lake, Endeavour was sitting quietly on the stand
when she was inspected by some Club Members !!.
Big sigh of relief from me  - - - when they finished they were smiling !.

 Hello,
 
 First picture of the boat with the trim lines and the waterlines on.
 The waterlines were rather hard to get right, because of the rather long overhangs of the hull.
 So, Endeavour now looks a lot more like the real one !.

Hello,

Sailing today, minding my own business, when two Ducks landed right beside the boat.
Gave me quite a fright !!.

John it isnt so easy on a model boat the set the jib and Yankee sails is it is on a real yacht as you dont have any cars to alter to set the
sheets for different points of sail, but you seem to have got it about spot on as she looks great on the water.
A really nice looking boat.

Hello Geoff

The biggest time saving gadget was the frame I made to hold the sails into the wind, as mentioned in Post#13.
Doing that saved  a lot of time setting and altering the sails.
No waiting for calm or gusty conditions!, full set of weather as and when it was required!.
Best bit of kit I have made for a long time.

 Hello,

Been out sailing Endeavour in our very nice weather.
Still sailing with the "Test Sails" will make some proper ones over the Winter months.
