Do-It-Yourself ROV tether for 21 cents a foot, (69 cents/meter) and 300 pounds (1300 Newtons) of load. SCORE! And we are looking forward to your suggestions for improvements. Thank you for your assistance!
The old plan was to have to ROV in the water this weekend and on display at the Tulsa Maker Fair in two weeks. ….I hate that plan. Deadlines suck the enjoyment out of most everything. I understand the need for them especially when other people are counting on you, but that is not the case. This was self imposed. It did not make me work any harder or better, it just made normal work feel like pressure and failure where there was no failure. I though I had learned that lesson. Over a year ago I took down the “Count Down to Launch Clock” from the web site. That felt great. And we have worked more and completed more on the boat this year than any previous year, and did it joyfully and while taking time to learn new skills help others learn new skills. We are about enjoying life and enjoying the journey. No more deadlines. We LIVE now and sail when we are ready and the wind is blowing. We enjoy every moment. If you don’t then you miss the special things. Like those socks. Much love and appreciation to our supporters and especially the Seeker Crew. Betsy and I are off to Florida next weekend to see this thing they call an ocean and scout out a Chinese junk rigged sailboat. Jack and Bart are in charge of the boat yard.
The ROV the internet built! We got a lot of great ideas for out ROV Hull Tool. You can see them on our last post: ROV Hull Joint Tool but the one recommendation you don’t want to miss was from Eddie DaGrouch. We are not accustomed to things working on the first try. We often use the motto “We build it right, because we build it twice.” …but Bart Robinson cobbled together a tool that works like a charm.
We also had some success in getting two sonar transducers to share a Lowrance SonarHub. When successful, we will have a deep water ROV with both forward and side-scan sonar abilities a fraction of the cost of commercially available products. –Doug
“Were having a blast, making stuff work with alot of help/inspiration All of the viewers, there ideas and thoughts/comments “Do” make it happen. Your all a good mind blast and the thanks given here can’t express it fully, just know you’s folks actually matter. Dreaming isn’t a sin, delaying/denieing the dream is..Rockon Worlds Peoples, give into your dreams !!” –Bart Robinson
You’re only as dumb as the smartest person in the room. And the internet makes for a really big room. Yes, you have filter out some trolls, and inflated egos, but what is left is a great cross section of humanity and experiences. There is definitely a need to make presenting an idea safe as there is unfortunately large body of ideas that are held back because of the fear of ridicule. That is unfortunate because any idea, no mater how seemingly impractical is fuel for better ideas. The next hurdle is picking an idea. Ego is the problem. Our ideas are like children and we tend to think they are the best and the brightest in the class. Pick one idea and it’s like you have dashed the other children against the rocks. We would all do well to let go a little more. In the end there is never a best idea because the variables are constantly changing. Current skills, tools, money, time, materials, easy of use, work environment, expected end of life; these variables all randomly dance about like Red Bull fueled teenagers at a rave. So relax, the picked idea is just today’s pick for today’s variables. And as soon as it’s built and in use, an improvement will be clear and we can return to the collection of ideas.

This ROV is going to be a remarkable tool for Seeker and anyone else looking to explorer beneath the waves. It’s not just another ROV with lights, cameras, and thrusters. This ROV as side scan and forward scanning sonar and can go to 3000 ft!
It’s lovely being back to work on the ROV and enjoying the air conditioning in the shop. Bart has reworked the LED light section so we can easily route the wires through it. I have the aft camera installed and more of the wiring harness and Betsy has been working out our sail plan and sharpening her sail sewing skills making a ditty bag. We have also decided to go with bamboo for the sail battens. Please let us know if you have a tall stand in your yard and your not further than 200 miles. 🙂
I’ve been listening to “The 7 Habits of Highly Effective People” lately, ….actually I’m on the second time through it. There will likely be many more times. Habit #1 is be proactive. In short: Work. Work on the things you can work on today. Do something every day to make your goal happen. Make work your habit. I suggest you put a picture up of your completed goal. You’ll see Chinese Junk Sailboats on my walls. Does it matter what you work on? YES, but there are 7 habits, this is just #1.
And thanks to Cody for all the CNC and Boring done last weekend. And Bart for adding some textured planks to the gangway. We are back inside, out of the heat and working on the ROV. –Doug
As the time counts down until we hit the water, it’s time to start working on the sails. It’s a massive undertaking even for someone who has an above average ability for sewing and stitchery. But despite my public school 7th grade Home Ec course, this is far and beyond the first pillowcase my grandmother taught me to sew on her Singer sewing machine. Even tailoring classes in college can’t compare nor the dozens of garments that I sewed including prom dresses, camp shorts, and outrageous Halloween costumes. These sails are HUGE! With that in mind, I’m ready to take on this textile endeavor.
When the plans for the boat were drawn up, a drawing of the sales was also supplied. While it gives us a basic idea of what we’re trying to achieve, it is in no way what could be considered a “sail plan” or “sail design”. The original drawing from the boat designer shows a few measurements on an outline that includes batten placements. By scanning this into cad and plugging in the measurements, we arrived at what is the general sail design. Fortunately it meets the ratios for what is called a “low aspect sail” in the world of Chinese Lug Sails but other than that… we’re on our own.

With this in mind, we made some calculations and arrived at some approximate measurements in order to calculate the yardage of sailcloth needed.
Mainsail: 1,251 sq feet or 139 sq. yards
Foresail: 710 sq feet or 79 sq. yards
Mizzen: 235 sq feet or 26 sq. yards

The color is Tanbark (though you might call it red)
Points to consider:
Now comes the hard part. How heavy must the fabric be and where do you get the stuff?
What’s interesting is that there are not very many junk rigs in excess of 50′. Most of the websites and catalogues for sailcloth speak in boat lengths up to 50′. The next largest junk rig we have to compare is the 60′ Magic Pearl which is being constructed by Robin & Kim. For their mainsail they chose a 10 ounce dacron. But we’re still 25% bigger.. so what do we do?
All Dacron sails begin at the same point — Dupont. The fibers are then woven, treated and heated and given catchy sailing names by less than a handful of Sailcloth makers in the world. I checked the retail outlets… but 8.5 ounces is the heaviest fabric I can find.
So I went Wholesale! I first contacted Bainbridge — an American company who offered a Tanbark sailcloth but only up to 8.5 ounces. FYI weights are per square yard… and a square yard for this weight measurement is actually about 32″ x 36″.
Bainbridge is a wholesaler so I knew that I might have a few problems communicating with a salesman, but what the heck. As I feared, Mario was not much help and really knew very little about the product or it’s possibilities. He told me to call a sailmaker as they would have to provide the prices and any other information. But I’m the sailmaker!!!!! I asked if it was true that their Tanbark product was only available up to 8.5 ounces. Yeah…said Mario… and furthermore.. no special orders! Mario was evidently in a hurry to grab a slice and head for the Jersey shore!
So I moved to the next on my list, Challenge Sailmakers. I could never find a phone number… take note! So I moved on to the next one…
Contender Sailcloth. A European company, they have an office (sales) in the US and I had a great talk with Tom at 508-674-7700. Their product is called Fibercon AP and it’s available in a huge amount of weights all the way up to 15 ounces! Furthermore, we can order directly from them AND they’ll even send us a sample! Woohoo… customer service! While Tom was very informed on his product he still couldn’t confirm what weights we’d actually need although I do have it narrowed down.
Thoughts:
Main: 12.5 or 15 ounce ($27 or $29/yard
Fores’l: 9 ounce ($18/yard)
Mizzen: 7 or 8 ounce ($17)
All together that’s $6-$7000. (Don’t go all bean counter on me. it’s JUST an estimate)
They have the lighter weights in stock.. but the heavier one will likely need to be ordered… no problem… we have a few years time.
Next assignment is to see if I can’t find somebody out there who has experience in sales for boats over 70′ in length to try and narrow down the weights. Tom suggested I find David Bierig in Pennsylvania. He’s a Tall Ship sailmaker. Who knows… in 50 years of sailmaking, maybe he’s come across a junk rig. But first.. we have to find a phone number.
When it comes to boating, as with most things in life, there is no substitute for experience. This time of year, as boaters all across the country are returning to the water, many are venturing out on boats for the very first time. Remember that for most of the places boating and sailing requires a license, before you continue reading make sure to get familiar with this boating test exam.
Many thanks to Cody Allan Rydell who spent a last weekend cutting gears and a day at the lathe. The bore is over 7 1/2 inches and had to be cut back almost a 1/4″. A huge job for our Grizzly lathe. Lots of chatter and heat with our 1″ boring bar and to top it off, this capstan did the strangest thing. Normally as the part heats up it gets larger on the ID, but this thing go smaller. I guess it’s the spokes that are supported by the drum, but he kept cutting and cutting without the progress we expected. But after cooling down, there was just 30 thousands left to go. We have one more to turn down and then we can haul them down to Super Dave who has a shapper that can cut the keyways. The keyway is 7 inches long, 2 3/8″ ID and about a 9/16″ wide.
