Trident Ultra Anchor Trolley Kit for the 4.7 and 4.3

Trident Ultra Anchor Trolley Kit

As with most owners of the Ocean Kayak Ultra 4.7 or 4.3 series kayaks we have found ourselves void of a couple of the “built in” features that are offered in the Ocean Kayak motherland (New Zealand). Though the bait well kit did recently arrive, the Trident Ultra anchor trolley kit is still vacant on US shores. So, many have found themselves coming up with creative ways to fill these seemingly simple voids in one of the best fishing kayaks on the planet. A great write up is available on Kayak Fishing Stuff’s website within the forums. Here we have come up with our own variation that I will detail below. We will also offer the hardware kits right here on the site so you do not have to reach out to multiple sources to gather the necessary hardware. No matter which Trident Ultra anchor trolley kit DIY you choose to follow or if you just need the basic stuff to set your own ideas in motion, we have what you need.

 The Materials

Trident Ultra Anchor Trolley Kit Materials

*The threaded inserts on your Ocean Kayak are an M5 metric thread, however SAE 10-32 threaded hardware will work just fine without damaging any of threads on either end.

For this Trident Ultra Anchor Trolley Kit DIY I used the following materials and hardware:

8 – 10-32 x 1.5″ stainless steel flat head screws

8 – Bungee Buttons

16 – Tooth type lock washers in 1/4″ size (these grab more material for what purpose we are using them here)

2 – Stainless steel/plastic pulleys with a length of bungee cord attached

2 – Stainless steel pad eyes that measure 1 3/4″ eye to eye

4 – 10-32 x 1/2″ stainless steel pan head screws

4 – Size 10 stainless steel washers

1 – 1.5 or 2″ nylon or stainless steel ring

About 35 feet of Mil Spec 550 Para Cord

Required tools: Drivers for your stainless steel screws, a dremel for shaping the guides, a drill and small counter sink bit, knife, and a lighter.

The Trident Ultra Anchor Trolley Kit Build

We start by removing the ropes and rope guides along the (port) side of the kayak that has the built in threaded inserts for the anchor trolley from Ocean Kayak. This includes all 8 guides along the entire side. Save the ropes and screws for future use and gather the 8 guides for a little trimming to make them into your new Trident Ultra anchor trolley kit anchor line guides. You will first want to use the drill and a small counter sink bit to make a seat in the guide bottoms for your new hardware to grab into for final installation. You will then start trimming each guide by cutting of most of half of one side. We leave a little over hang tab on this side to act as a simple guide for the lower anchor line (this will become clearer in the images and as we move along). See the images below that show these first steps.

The Desired Shape We Want To Achieve With Each Guide by Cutting Them with our Dremel Tool

Rope Guides Trimmed

You can see we just cut a portion of one half of one of the loops in the factory rope guides. This over hanging tab is important to your Trident Ultra anchor trolley kit as this will allow you to snap back your lower anchor line nice and neat against your boat when not in use.

We then stack some hardware as shown above. The order is important as the Trident Ultra anchor trolley kit hardware will not fit correctly in any other. You have your trimmed rope guide, a lock washer, an inverted bungee button (rounded side down), another lock washer, and your 1 1/2″ screw running through all of them. In this order you can tighten them back into the guide inserts all along the side of your kayak (as shown in the next picture). The lock washers will keep this assembly from rotating under the load of actual use. We also chose the 1/4″ size lock washer and not the size 10 because they grip a larger surface area of our plastic hardware. You can also see the counter sink tap we gave each guide allows the flat head screw to seat neatly into this new guide assembly we have created. These all work together to create a rigid assembly from many small parts.

Rope Guides Trimmed

We can now grab our pad eyes, the 1/2 inch screws and flat washers to install the pulleys at each end of the kayak at the factory inserts located at the bow and stern. I would suggest to go ahead and hang your pulleys with the bungee cords onto the pad eyes before mounting them to save your self from having to tie a knot in close range to the boat. The flat washers are necessary again to ensure a tight fitment of the Trident Ultra anchor trolley kit hardware. Since we are converting from metric to SAE we find that an exact fit is not exactly possible, but this systems allows for the closest and strongest fit for our purpose.

Pad eyes and pulleys installed

Now you basically have the “nuts and bolts” of this set up bolted to the kayak. It is time to simply run the anchor line through everything. I chose 550 para cord because I have a lot of it, it is cheap, useful, and well.. can handle 550 lbs of stress. Perfect for me. Simply run the line through one of the pulleys, pull it along the top of your guides (the closed ends) and run it through each one until you reach the pulley at the other end. Bring both ends to center and tie each to the nylon ring. Here is where you will cut the line to size, and I like to melt the ends back to the knot to ensure no snag or fray. You want to pull them tight enough so that the bungee ends are just taught and the final line assembly is firm. You can then slip the lower line under the open sides of the guides and you will find it rests nicely for the entire length of the kayak.

So, does it work? Yes, very well. The first thing your going to want to do at this point is start pulling the line up and down and see it go. That’s fine, just be sure not to get upset if the ring hiccups across these mounts. With no load it may, but in actual use, no matter how it is used, the tension keeps the ring free of the guides and the whole rig glides very smoothly. After you unhook from anchoring the lower line may lose the lower guides. This is something I see on every anchor trolley rig, but with this rig you can simply push the line down from where you are seated and it will grab the lower guide tabs and be nice and neat again.

I tested this for the first time during an offshore fishing tournament. The day had a steady North current and a North bound wind working together. I threw on my drift sock with this rig to park over some wrecks and it worked flawlessly. I have no doubts in the useability and build quality of this rig.. or I wouldn’t be putting it here.

Oh, and if you find that the trolley slips from where you want it during some extreme conditions, no cleat needed here, just loop the trolley line over one of the guides and it will be fixed in place. See image below.
