RUDDERLESS!
I’ve been growingly concerned that this latest passage has been going far too well and that you might be getting bored with all these Emails about blissful sailing day and night in this private universe we have out here. Up till about 5pm this afternoon I was going to post another brief update to say that we’d had just that, another day of blissful sailing through a moonlit night and a sunny day under blue skies and only a few hours of storms and squalls. But thankfully that all changed quite quickly and we now have the first of what I’m sure will be a multi-part entertainment show for you. Christine and I had been having another leisurely day of chatting and going through the big onboard atlas to show each other places we’ve lived in around the world. This takes quite a bit of time for both of us as we have grown up traveling and camping with our respective families and then continuing to live and work around the world as adults and so we both have lots of stories to tell from all our travels. Little did we know that we were about to add another great story to this latest adventure called life.
It all started quietly enough a bit after 5pm when the head sail backed and LTY slowed down to under 2 knots after passing through a storm cell of some high winds up into the 40’s and a good downpour of rain. This has been the pattern for the past few days, sailing in excellent conditions with winds 20-25 knots and today moved over to being out of the East which is just perfect for our course of 350 degree we want to be on to sail past the west side of Milli island, the southernmost of the Marshall Islands and then up to the east end of Majuro atoll. Christine was at the helm trying to steer the boat back on course as she had done countless times before but wasn’t having any luck in getting the boat to turn. She asked me to take a look and see if I could see why LTY was acting so weird but it did the same thing for me. You would turn the wheel, the rudder indicator would show that the rudder was turning but no matter if you turned it all the way to port or all the way over to starboard the boat didn’t turn?
So we flipped into our Watson and Holmes super sleuth detective mode, (I AM with a murder mystery author par excellence after all!) and we started trouble shooting the problem. The hydraulic steering rams and rudder post and arm are all under the aft cabin bed so I took that all up so we could see what was physically happening with the rudder and steering. I watched as Christine turned the wheel and it all worked fine; turning the wheel moved the double acting steering cylinders which turned the rudder. Next I removed the covers on the hydraulic steering pump which is turned by the steering wheel in the cockpit and found that the hydraulic fluid was low. This sounded promising as the problem because if there was air in the system it would just compress and the rudder wouldn’t turn or could be moving on its own so we set to work adding new fluid and bleeding out all the air in the system. Seemed to work well, got lots of air out we slowly added fluid and it took about ½ a liter of ATF oil to fill the pump fully and within about 10 minutes we had all the air out and were ready to test it all out. Fired up the engine, turned the wheel hard over to port and …………………………………………………. NOTHING! Turn the wheel hard over to starboard and ……………………………………….. NOTHING! We had NO steering?!?
Very strange because I could go back to the aft cabin and watch as Christine turned the wheel and confirm that the pistons moved which in turn rotated the rudder arm mounted solidly to the top of the 2” die SS vertical rudder post which goes out through the bottom of the hull and has a big 6” diameter flange which is solidly bolted to a matching flange on the top of 2” SS rudder post that is part of the rudder itself. LTY has what is called a “skeg mounted rudder” which means that there is a large vertical “fin” that is welded to the hull and extends down to the bottom of the rudder and has a big beefy arm on it which holds another short 2” SS post with flanges to attach the bottom of the rudder. This is a VERY solid rudder system as the rudder is solidly attached both top and bottom to the boat. So it was definitely puzzling that we could watch the rudder arm and upper post turn just fine and yet we seemed to have no steering?
The only thing left to do was to go dive on the rudder and check out what was actually happening under water and so we pulled in all our sails, I donned flippers, mask and snorkel, Christine tied an old nylon line we have attached to the aft swim steps around my chest to act as a safety tether and I dove in. Of course the other pertinent bit of data for you is that while we have pretty much stopped LTY from moving, the wind which was running about 25 knots was still pushing us forward about 1.2 knots and it was also producing some reasonably big swell and seas which were running about 2-3 meters. So LTY was rocking and a rolling very well in these conditions and that all translated into a LOT of action at the stern where I was now swimming around. As these big swells would come in the water level would rise up and down 2-3 meters and they would lift LTY up and pitch her forward and roll her from side to side but of course these actions are not in synch so the net result is that the aft end of LTY where I’m trying to work is now lifting up completely out of the water by more than a meter and the water is dropping down even more so it is a bit like being in a giant wave pool that happens to also be in a giant blender! However I was able to hang onto the swim ladder with one hand and the nylon tether rope with the other and keep myself dangling from the aft end of LTY as she rose up and down and rolled from side to side and keep my masked head down into the water enough of the time to be able to see the rudder. It was starting to get a bit late in the day and the sun was getting low on the horizon but there was still surprisingly good light underneath so I had a very clear view of a very bad situation. The rudder was freely swinging back and forth like a big loose fence gate in a wind! Huh?? How was that possible when the rudder post inside the boat and the steering wheel were perfectly still?
I did my best to time my dive to be just after one of the waves came through and down I went under the boat to get over to the rudder and take a closer look. It was a bit tricky with the rudder flipping randomly back and forth from side to side but there are four large zinc anti-corrosion blocks bolted to the aft end of the rudder so I was able to dive down, grab hold of one of them with one hand and push my other hand up against the bottom of the hull and in this way I could stabilize myself, well sort of, and keep the hull and the rudder at bay and not be bashing my head or slamming my body. Worked pretty well and let me get a good close look at the rudder situation and I could then clearly see the problem. The rudder post where it comes out of the top of the rudder and is welded onto the big flange had broken completely off so that the rudder was now only attached by the bottom post/flange assembly going into the skeg and meanwhile the upper rudder post from the boat was completely detached from the rudder so it was sitting nice and still while the rest of the rudder assembly flopped freely back and forth with the force of the water. Not good!
This meant we had no steering at all now and fixing it would require hauling the boat out and rebuilding the top rudder/flange section so not something that could be fixed at all at sea or with the boat in the water. Hmmmm, what to do now? Well out of breath by now I did my best to kick my way free of the thrashing rudder and smashing hull and try to get back to the surface clear of the aft end of the hull and the swim ladder. Worked reasonably well and I was able to grab the swim ladder on one of its trips down to smack me and hold on well enough to breathe and talk to Christine and give her the brief summery; we’ve got no rudder dear!
Now what? Well, first order of business is to get the rudder tied off somehow so it isn’t swinging wildly back and forth and to also make sure the rudder is well attached to the boat because it might now be possible for it to come completely away at the top and the weight of this huge rudder in these seas could possibly snap off the bottom shaft and the rudder would break free and head for Davey Jones' locker/parts department. So I asked Christine to dig out a length of 10mm line, tie it off to the boat and toss me the other end. My plan was to see if I could get this looped through one of those zinc anodes that are bolted to the aft sides of the rudder and then run the line up the side of the hull and tie it off up on deck. With one of these on either side I could stabilize the rudder’s thrashing and also keep it attached to the boat should the whole thing break free. Sounded like a good idea but even after I was able to glom myself onto the flailing rudder like some cowboy riding a bucking bareback stallion, there wasn’t enough space between the zinc anode and the rudder to get the rope through so I would need to pry it away with a crow bar or come up with another idea.
Trying to hang onto a heavy crow bar and pry the steel bar inside the zinc anode away from a flailing rudder just wasn’t going to work so the better idea was to lasso the whole rudder with a loop of this 10mm line and cinch it up tight with the line coming off the aft end of the rudder. If I could get two of lines on like this I should be able to pull one up each side of the hull and stabilize the rudder’s movement and maybe even figure out some way to still move the rudder into a position and hold it there and actually give us back some steerage. Amazing what even my tiny little brain can come up with while thrashing around in the open ocean! We went to work to get this line fed through the tiny gap between the aft edge of the skeg and the forward edge of the rudder without having it guillotine my fingers off, then bring the end back to the aft end of the rudder, tie on a slip knot and feed the other end through and back up to Christine so she could pull it tight and up the aft side of the hull. It took us about an hour to do so as there as a LOT of water “action” back there lifting me up into the air one minute and then plunging me down the next. All quit manageable really but the new problem was all these lines that were now also thrashing around and wrapping around my legs, ripping off my mask and snorkel and creating a real tangled mess of lines around my legs that I was busy trying to turn into a lasso and tie off tight to the rudder.
The worst was actually the line I had purposely tied around me for a tether as it was this well weathered nylon line which had turned into this stiff wire haired snake that was now rubbing my skin off in large welts all over my arms, chest and legs. So I managed to climb back aboard LTY and get onto the bottom transom step to take a quick breather, untied the abrasive tether and had Christine find a softer line and tie it around me for round two of rudder wrestling. Eventually we persevered and got two of these lines wrapped around the rudder and cinched up tight. The anodes worked well as stops to prevent the lines from sliding up over the top of the rudder and we were then able to bring the other end of these lines up each side of the hull and cleat them off to the bottom of the large SS poles bolted onto the aft corner of each side that are the posts for our radar and wind generator. WHEW!!!
It is now almost 7am and so I’ll sum this all up for now by letting you know that after lots of experimentation we’ve actually been able to come up with a great little system where we have these lines from the rudder holding it off to port and keeping it in position and then adjusting combinations of the head sail furling and sheeting to hold a course! Works amazingly well so far and we’ve even been able to play around with the rudder angle by tightening and loosening those two lines coming off the rudder and then adjust how much head sail we furl out and how much we sheet it in and are slowly figuring out how to steer this way. The wind of course is a real challenge as we can’t control its direction nor velocity and as it changes we need to change our setup to keep everything balanced and keep us on a set heading, but it’s working amazingly well so far.
Christine has had a few hours sleep and so she’s going to spell me off now for a bit so I can get a few hours myself and then when the sun comes up I can dive back down and attach some more lines and figure out some ways to perhaps rig up these lines through pulleys to the dinghy davits or something to be able to adjust them a bit more as we go and give us some actual steering control. So for now, all things considered, we are going GREAT! We’re safe and in no danger, we’ve got some reasonable ability to steer and stay on a course and we’re making pretty good speed towards Majuro still. I’ll do my best to get back to you later today with the update of how we manage with all this but for now there’s no need to worry and we are both smiling with that great feeling of satisfaction of once again turning adversity into adventure and we’ve added one more story to our list! Who could ask for more?
Night for now, well morning really so this is the good ship Learnativity signing off.
Christine, Wayne & Ruby the Wonderdog.
