After nearly sinking, THIS is what I did about it.

After nearly SINKING my boat, this is what I did about the faulty thru-hull that caused all the problems... See the unboxing and installation of the Echoplilot forward scanning sonar.

  • What editing software do you use and do you use a Mac or windows computer. Great videos!

  • You must be great fun in a leaky bath tub with all your plugs

  • But why did the speed transducer fail in the first place. Somewhere i missed the explanation.

  • Get a job!!!!

  • I was asked to write a report condemning a multiple loop HF antenna in Hong Kong in readiness for our pull-out. The antenna had never worked. It consisted of a number of hoops in a line that were supposed, with the appropriate length of co-ax from each loop, to be additive for a signal coming from a specific bearing and elevation. I discovered that the installation team had 'improved' on the design by using LDF4-50, a low loss co-ax, instead of the URM67 specified to each of the loops. The problem is that the velocity wrt to the speed of light is different in the 2 co-ax types and the installation team had not adjusted the co-ax lengths accordingly. Instead of condemning the antenna I suggested I could repair it by adding in lengths of cable, which did not make me popular with the staff that wanted to get rid of it.

  • I hate to be that guy, but I do like passing along knowledge. If you use the entire length of the saw blade it takes less work.

  • Lessons learned from sinking a boat. I agree, what better than to watch someone with your experience.....2 boats. Not being a jerk but honest.

  • Never cut the cable...should have been the title of this video;)

  • How did your speed transducer fail and almost sank your boat. How is that possible.

  • LMAO what a fantastic manual! Please do not cut the cable!

  • If you find one at a good price, I have a Dozuki (Japanese saw that works on the pull stroke). It works much faster than the traditional North American style saw, is smaller, sharper, and the one I have comes apart at the handle quickly to change out the blade when dull- which makes for storing on a boat even easier! I was a finishing carpenter for years and it was my 'go-to-saw'.

  • I can’t find where you talk about exactly what happened to the transducer to cause your problem.

  • Did you cut the cable??

  • ...why the music...??? the ''background'' music is in the FOREGROUND TOO MUCH..... music forces itself to the stage and leaves you sittin in the audience trying to ''talk'' ......

  • dont cut the cable (cable extension $1000 per meter )

  • Super quality job on the transducer James .

  • to use the same hole , put a piece of glass over the existing hole ,,let cure .. mark center and wala..

  • Obviously there is a reason for not doing it, but looking at the "protrusion" you had to build up on the hull i would have thought the manufacturers might have been able to include a pre moulded and drilled poly block that would have fulfilled the requirements of where the sensor has to point.

  • 🚢 ⛵ a captain teaches shares & helps others on their boats. Enter capt James. The knowledge ive learned is un-repayable. Many thanks sir ⛵ 🌴

  • just put another board over the existing hole and drill through that and then the hull the board keeps the drill centered until it has a good bite in the hull easy same thing you do on a door handle if you have to drill it bigger hole for the handle or the 2 drill size method mentioned below works good as well

  • I find it funny that such care is given for the transducer to be strait as possible when it's a mono hull sailboat that will rarely be strait up at any point.... Jus Sayin Yo

  • More expensive new shit you didn't have to work for, it wasn't the speed transducer that nearly sank the boat, it was your negligence and lack of experience

  • Awesome job and the music was on point.

  • Great show on this one. Curious as to how you ensured that the boat itself was straight and level before using a plumb bob to determine vertical.

    • I was wondering this as well. Seemed to assume the boat itself was level since he was using the plumb bob. So unless there was some behind the scenes checks, it's very likely that despite his ingenuity, it could still be installed off axis.

  • 6:34 I've got exactly the same sonar and in my instruction it doesn't mention about cutting the cable on each paragraph only once at the end .Are you sure they didn't make these instructions specifically for you?

  • nice job on that thru hull work that was awesome

  • Love the work.. I have a wood fairing block inside and outside for this. I epoxied over the outside and faired -just did 4200 on the inside block. Did you Epoxy the thru hull, that’s what it looks like.. just curious how you finished that one. Looks good dude, love watching your $hit. 🤙

  • Great video (largely thanks to the audio), cheers! Liked and subscribed.

  • Ryobi battery powered drills have a round bubble level on the back of the motor. Round bubbles are cheap, and I've even used a cheap compass (think Rambo knife) glued to a Makita.

  • "NEVER FREAKIN CUT THE FREAKIN TRANSDUCE CABLE!" Hmmm, wonder what they meant? Ha! ;)

  • Meanwhile kimmy has had 25 new partners. Her loss bro.

  • Try to keep all the wiring out of the area under the floor if possible. Engine starting batteries high as possible and completely isolated from everything else, even separate charging system if possible. Bulge pumps are cheap. You can have a spare with alligator clips and hose that can go anywhere. You can run pumps off the engine battery once it is going and being charged. The other biggie is exhaust high as possible before the water goes in. Fixed a lot of motors with sea water in them. You are on the right track learn what does not work and do it better. One day it will all be worth it.

  • Good one mate

  • Hi I like your Arnold Schwarzenegger voice can you repeat it in another video it is great! :) LoL kind regards Alex from AUSTRIA

  • Ahh yes I love sidescan and forward looking sonar for fishing.

  • Hurricane season starting early it looks like.

  • That time lapse was really satisfying to watch. Nice V

  • Nice work.

  • 10 minutes?...

  • They are great to have for sailboats. Always something. WOW. He keeps pushing forward. Never gives up. That's the Navy in him.

  • I thought for sure you cut the cable!

  • I had to chuckle what is level on a boat. When you are going up a wave or down. On a beam reach ? I do say forward facing sonar should face forward but level ?

  • No guy wants to hear “ this isn’t gonna be long enough “ 😂

  • Great video, and Love the music! What product did you use to fill the fairing around the through-hull? Was it La Yogurt Probiotic?

  • Transducers are generally calibrated at the factory (application dependent of course?) from the factory so again cutting the cable screws up the calibration making the displayed values inaccurate. When sailing sometimes inches can really matter so: PLEASE DO NOT CUT THE CABLE is sound advice.

  • James great upgrade to your ability to "sea" down below so to speak. If you run aground or potentially sink your home again perhaps sailing just isn't for you? 😆 LOL, great to see you recovering from some flat out shitty luck recently, never doubted your resolve or abilities.

  • what is wrong with going outside and working out

  • Do NOT keep your wooden plugs like that wired to the valves. When the throug hull fails, the plug wil get wet and swell before you push it in the hole. You want the plug to swell after you push it in there. Another disaster in the making.

  • Keep it up CAPITAN Jim! We will be watching you closely! Are you planning to take Zingaro 2 somewhere soon?

  • James, please make an episode on how you safety wired your transducer. :) The Echopilot manual I looked at didn't show how. Airmar do. Their example runs some lock wire around the threads of the bronze thru hull if you don't have eye holes, twists and then runs the wires diagonally up over the locking collar and around the transducer body, or in your case you could go around the bronze rod handle before twisting them together.

  • In drydock i would have sanded inside and out, taped plastic on underneath and laid in fiberglass. 4 hours later, removed plastic, put a coat of gelcoat on, then in a couple of hours, re-drilled hole.

  • One method for obtaining a true vertical for the device would be - having once made a small pilot hole in the hull to mark the right location - to work from the outside of the boat, as this will allow whatever alignment method you choose to be done with all the room and access you could hope for! This assumes that your boat is on the hard in a true vertical position to begin with! However this is necessary whether you're working from the inside OR the outside - otherwise your hole will be vertical but through a "non-vertical" boat!!

  • James next time you need to drill a bigger hole like that put on the hole saw u want and then screw on a hole saw that fits the hole. It will extend into the hole and guide the new size thru with little to no wobbling. they do make two different hole saw shanks one with shallow screw and the other can take 2 hole saws.

  • "Never Cut the Cable!" hhh

  • cats meow= dogs bollocks

  • What amazes me with James is that *Miðgarðsormr* (the Midgar Serpent) tries to wreck him time and again, but he will always flourish time and again ....

  • Beter ik zou alle doorvoeren zo maken geen plastic meuk meer!

  • Water in your fuel tank maybe.

  • So if the transducer needs to be plumb while on land , what will it be while heeling the boat when sailing , not to mention riding up and down waves ? Heeling would show you an image that would be incorrect , right ?

  • Now that forward scanning sonar looks like a very handy addition to the inventory, and 'gratis' too! BIG shout out to Echopilot for the very generous gesture!!!! After what the vessel has been through James all starting to come together nicely - and repairs in the marina, either by luck or good management, I expect is your preferred option lol!

  • Hi James, I was watching another sailing channel where you dropped in to help a yatchie install some new sails. I just want to say you are a fair dinkum legend and inspiration. The world needs people who are prepared to act as beacons or lighthouses, to show and inspire others how to behave and what to do in stressful situations. You are a lighthouse to your community, stand tall.

  • You must cut the cable, hehe.

  • Oops some one else said that.

  • Cool boat, the other way to do the hole saw thing is to drill the hole in a piece of plywood stand on ply piece in bilge and bingo , called a hole saw collar

  • Nice job. How deep or how shallow can the forward sonar work? I've heard that they do not work in shallow water very well. But that may be older technology

  • the funny thing i saw was you pulled out a power tool then went back to a hand saw now that is classic

  • I promise I will never cut the cable. Not never.

  • You'll understand why they say DONT CUT THE CABLE if you do - Very intricate wires , Very

  • Note to De Walt - sell an accessory guide kit to attach to your drills.

  • Next time drilling a hole with a center bit, try a block of wood 3/4 " drill that out first then put it over the the area to be redrilled as a guide . hold it in place till the teeth are seated then continue through..

  • no eyeliner?

  • Expert guy with problem solving

  • Nice work 👊🏽

  • Hmmmm...too many maintance videos and few sailing... I look back when I see sailing video. Best of luck

  • Next time you need to open a hole with a hold saw ,,, get a piece of wood I like 1/2 thick and clamp it or hold it some how in your case I would get a piece large enough I could kneel on it to hold it in place. drill thru the wood and into the fiberglass. the wood will keep the hole saw aligned.

  • Does current fwd-looking sonar have enough resolution to detect deadhead logs floating just under the surface? Or is it limited to ground topology forward of the boat?

  • That was an ingenious way to deal with installing that transducer and enlarging the hole for the thru hull. I'm impressed, guess you have some skills after all. : ) Thanks for the video! Oh you should consider getting your self a Japanese "razor saw" it has a very thin kerf and cuts on the pull stroke. They are a very handy saw to have in your tool kit.

  • You need to put the hashtags on your vids. Even Echopilots gear :)

  • Nice to have the forward view. Kinda makes you wonder why that is a new technology??? Great video.

  • What about the level of the boat? Wouldn’t you have to be certain that the boat is sitting in dry dock exactly as it would in the water?

  • Really nice job with the transducer, captain.👍

  • Forward looking sonar is only ok if someone is looking at a screen 24/7 . I hope you fix this in correct ,it's the same as the speed transducer .

  • Cutting the cable and even soldering it with the same length back together will create an impedance change at that soldering position and therefore creating extra reflections that will cause the computer algorithm the fail. So don't cut the cable.

  • Call me crazy but watching this episode coz I see no painted nails :) on masculin and tattooed dude :)

  • James is a through hull master, and the music was quite pleasing as well.

  • iv always wondered why the last owner never cut the 10+ meters of cable on the transducer. thankfully i dont touch stuff i know nothing about so its all good xD

  • James, you mention a few times that the equipment needs to be 'plumb' Surely the closer the better but when is a boat in the water 'plumb'? Maybe in a quite bay set up a 'benchmark-reference point' for future use. I'm thinking a 3"x3" flat piece of wood shimmed up 'plumb' in some dish cupboard, out of the way, away from getting crushed or kicked

  • Good to see you James Well done Stuart in Ireland

  • Love the Dr Emmett Brown hair lol

  • Eyes on the prize. Everyone is watching and rootiing for your return to blue water. No pressure!

  • Do you Remember when you started ??? You said, And I quote !!! "I'll be ready to sail to Florida in 2 Weeks" !!!!.....LMAO. Things happen for a reason....Your doing a Great Job James !!!! Slow down and be careful....Just think, had you left early you would not have gotten all that Nice equipment for free....Your going to love that forward scanning sonar, especially in the Bahamas....Just remember to turn it on !!! All the Best bro !!! Question.... does the sonar come with the Fish finder feature....thats really handy

  • Mega job man !!

  • Thanks James. I took your advice on the needing to drill a bigger hole with a hole saw thing. It helped out big time.

  • A great job! Fair winds and following seas!

  • I had never seen a forward scanning sonar before I bought my boat that has one from 90's. Still works great! wish they were more common place then they are and cheaper

  • Hey James!! Please don't cut the cable!

  • Aha! I just wondered... The Man. The Myth. The Concept. Always so relieved to see you’re okay Captain!

  • Nice Job!!!!! I see a tech install video coming soon! Cheers from sunny White Rock, BC Canada....CHEERS!

  • When talking about Sonar and how it works, it's worth reminding the audience that James was Submarine Sailor in the US Navy... that definitely explains all the tattoos, for sure.

    • I think he did navigation on the submarine also which sounds pretty intense.

  • What did you have to do to prevent/reduce salt water corrosion in the electrical systems?
