Some more tweaks in order.

* A drain plug would be a nice addition
* Add a Jib Line Guide to the Mast step area. Same guide AQ is using at the Stern. (see pic)

Pics of the Mast step that is pinching the line as you navigate the course.

Also the Green lines are my Angle Indicators set at 80 degrees. You can see the short extension I am getting (boom vang) when I have about 3-5 degrees off midline when the Main Boom is close hauled.

How are the sails holding up? Are they made from mylar or cloth? I'm curious as I need aset for my Voyager and I saw the sails are available seperately...
I'm also wondering how they attach. Thanks for any info.

JD, String,
Great stuff! Pictures are terrific, and I can see the dock and the shoreline you boys are dealing with. Not as bad as I imaged. I will be following your up dates on the correction to the sail control issues and the water intrusion.
Water leaks bug me!
Thanks guys
Boomer

To discuss your issues with the Vela, I suggest you contact Aquacraft at http://www.aquacraftmodels.com/techsupport/index.html
I would ask to speak to the developer/R&D guy who is featured in this video. He should have lots of experience with the boat.

The booms not sheeting out to 80% - You should not have to be thinking about changing the sail servo. The manual says you are supposed to be able to sheet out to 80% with the TX set to sheet in tight to the midline. Possibly something is wrong in the rigging or the sail servo arm is not moving its full specified(?) travel arc. Or the manual is wrong.
The pinched jib sheet - That sounds like something is not rigged right or it's a basic design problem. You might temporarily try placing a piece of tape or something at the bottom of the mast to keep the sheet from going under it.

JD.... I am going to try one of these on my China Team. With the narrow hull I need more travel on the sail servo double arm. Might give you more outhaul also.

I dont see how its a rigging issue. Its a issue getting enough line travel to fully outhaul the sail.

Inhaul is limited by the Servo Sail Arm hitting the Keel tube. There is 155 degrees of Servo Sail Arm Travel end point to useful endpoint. This is only providing approx 7 inches of line extension/retrieval.

All of this is being done with the Boom Vang adjusted to provide Main Boom parallel to the deck.

I think the 3.5 Turn Hitec Sail Drum Servos only provide the same amount of line travel. Noticed a servo recently from xxx Brand china that listed 6 Turn Drum. That should do the trick if the drums not too small.

BTW - I think this is a great performing boat. And most people would do well with the boat as is. I just want the max performance possible. Id rather detune the travel available, then not be able to add it.

Im racing smaller, and sometimes swifter Seawinds that have max outhaul for the downwind legs. I dont want to give up any advantage I can have carrying more sail then they can on this section of the course

Seem to be doing well. Some of the ink has a few scratches missing, but no torn or extremely creased marks. They appear to be a mylar blend of some type. They call them thermal plastic mylar something of something somewhere.

They are inexpensive for a set and have great visual on the water.

Ive watched every video I can find on the Vela sailing. The AQ videos all show what appears to be extra outhaul on the Weather Mark leg setup.

I can adjust trim so I can acheive max out for downwind. But that would really affect the slot tuning on the jib when trying to sail close hauled and reach's. Id rather not compromise one that much for the other, in either scenario.

Hey there,

For your sheet ravel problem...Looks like the stock set up is a single purchase system. You can get yourself a turning block from Graupner online...or more expensive options as well....then basically you will tie off one end of the sheet line to the inside of the boat where the sheet actually exits. Then the line would go around the block on your sail arm, back through the existing hole to run like you have it....This will in crease your sheet travel by 2. You could then shorten your sail arm, increasing your overall torque to fine tune your needed sheet travel. Easy fix!

RG-sailer, knew there was a way to do that, just not sure how. Could you post maybe a drawing or a picture of the set up so I can get it right in my head.

Thanks.

It works with one very big "but": the effective pull on the sheet is halved with double hauling. Servo travel extenders also work, but at the expense of speed and resolution.

Yes you would double the pull on your servo, but he could also shorten his arm from the current length to regain some of the lost power while lengthening his line travel.

The middle diagram on page 58 here is probably closest to the setup that might work for you http://www.theamya.org/boats/us1m/pdf/us1mconst.pdf
