I’ve seen it a thousand times. Someone buys a fancy anchor trolley system, all sleek lines and promises of unmatched boat control, only to have it fall apart faster than a cheap tent in a hurricane. The biggest culprit? Skimping on the fasteners. So, you’re probably wondering, are screws enough for a n anchor trolley system, especially for those moments when the wind kicks up and you’re relying on that system to hold you steady?
Let me tell you, I’ve learned this lesson the hard way, with busted hardware and a boat that decided to drift into the neighbor’s prize-winning petunias. It’s not just about buying the right trolley; it’s about how you mount the darn thing. Cheap screws might seem like a good way to save a few bucks, but they can cost you a lot more in the long run.
We’re talking about the difference between a system that works flawlessly and one that leaves you scrambling. This isn’t rocket science, but it does require a bit of honest assessment about what’s going on when your boat is under strain.
When Screws Turn Into a Gamble
Look, the idea behind an anchor trolley is simple: it lets you reposition your anchor on the fly, which is a lifesaver when you’re trying to set up for fishing or deal with changing wind and current. It’s basically a pulley system running along the side of your kayak or small boat. You attach one end to the bow, run the line through a pulley or ring that slides along the side, and attach the other end to your anchor cleat or a stern cleat. The magic happens when you pull on the line, sliding that trolley point forward or backward, changing your anchor’s position without having to reel in and redeploy. Sounds brilliant, right?
The weak link in this whole elegant setup is almost always where it attaches to your vessel. Most of these systems come with, shall we say, suggested fasteners. Often, it’s a handful of small, shiny screws that look like they belong in a picture frame, not holding a boat against a tidal pull. I remember my first foray into anchor trolleys. It was a simple kit for my inflatable dinghy, and it came with these tiny, brass-plated screws. My buddy, who’s been on the water for decades, took one look and said, “You’re gonna need more than that, chief.” I, in my infinite DIY wisdom, scoffed. They looked fine! They screwed in easily!
Fast forward a few months. I was anchored in a pretty decent chop, nothing extreme, but enough to put a bit of strain on the rig.
Suddenly, I heard a sickening pop. One of the trolley’s mounting points had ripped clean out of the inflatable hull. Thankfully, it was just the trolley and not my anchor line, but it meant I was dragging anchor.
It was a humiliating and slightly panicked experience, trying to re-secure the whole mess while being pushed towards a dock. That’s when I realized that the question of are screws enough for a n anchor trolley system is a important one, and for most of the cheap kits out there, the answer is a resounding ‘no’ if you want reliability.

What to Look for in Fasteners (beyond Shiny Metal)
So, if those little screws that come with most kits are basically junk, what should you be using? It boils down to a few key things: material, size, and type. Forget anything that looks like it’s made of soft brass or tin. You need corrosion-resistant, strong materials. Stainless steel is your best friend here. Specifically, look for marine-grade stainless steel, like 316. It laughs in the face of saltwater and UV rays, which is exactly what you want for anything exposed on your boat.
The size matters. Those tiny screws are often #6 or #8. For a system that’s going to be under constant stress, you want to go bigger. I’m talking #10 or even #1/4 inch screws. The longer the screw, the more material it has to bite into, and the stronger the hold. On my current setup, I upgraded to 1-1/2 inch long stainless steel screws. This made a huge difference. The mounting points feel solid, like they’re part of the boat, not just precariously attached.
Then there’s the type of screw. For mounting to solid fiberglass or wood, lag screws or stainless wood screws with a decent thread depth are a good bet. If you’re mounting to a composite material or even a sturdy plastic hull, you might need to think about backing plates or even specialized threaded inserts. Don’t just wing it. Think about what the screw is actually biting into. A screw that’s only grabbing a millimeter of plastic is going to pull out. I often use stainless steel bolts with large washers on both sides, and a nylon locking nut on the back. It’s overkill for some applications, but it’s peace of mind.
Here’s a quick breakdown of what I generally look for:
| Fastener Type | Material | Typical Use Case | My Verdict |
|---|---|---|---|
| Small Wood Screws (Kit Supplied) | Brass-plated, Zinc-plated steel | Light duty, non-important items | Avoid for anchor trolleys. Guaranteed failure. |
| Stainless Steel Wood Screws (#10 or #1/4) | 304 or 316 Stainless Steel | Fiberglass, wood, thick plastic hulls | Good baseline upgrade. Make sure sufficient thread bite. |
| Stainless Steel Machine Bolts (with nuts & washers) | 304 or 316 Stainless Steel | Requires drilling through, good for composite/plastic, ultimate strength | Best option for reliability, especially with backing plates. |
| Threaded Inserts (Heli-Coil or similar) | Stainless Steel | Holes in plastic/composite where bolts are preferred | Excellent for creating durable bolt holes in weaker materials. |
The key takeaway is to look at the fasteners as part of the system’s integrity, not just an afterthought.
Common Mistakes That Sink Your Trolley (and Your Day)
It’s not just about picking the right screws; it’s about avoiding the wrong practices when installing your anchor trolley. I’ve seen people do some truly boneheaded things, and I’ve been guilty of a few myself in my younger, more impatient days. One of the most common errors is not considering the material of your boat and how the screw will hold. If you’ve got a thin plastic kayak, just drilling a hole and screwing it in is asking for trouble. You need to think about spreading the load. That’s where backing plates come in.
A backing plate is basically a piece of metal, plastic, or even thick plywood that goes on the inside of your hull, behind where the trolley mount attaches. You then drill through both the hull and the backing plate and use bolts. This distributes the force over a much larger area, preventing the screws (or bolts) from tearing through the hull material. I learned this when I mounted a trolling motor bracket on a small fiberglass skiff. The first time I hit a moderate wave, the bracket ripped out. A beefy aluminum backing plate and some properly sized bolts fixed it permanently. It’s the same principle for anchor trolleys. (See Also: Do Nvme Drives Come With Screws )
Another mistake is not pre-drilling holes of the correct size. If you try to force a large screw into a hole that’s too small, you’ll split wood or crack plastic. If the hole is too big, the screw won’t have enough bite. The general rule for wood is to drill a pilot hole about 60-70% of the screw’s diameter. For plastics, it can vary, but you want a snug fit without forcing. Sometimes, drilling a slightly undersized hole and then gently tapping the screw in can create a stronger thread in plastic.
Over-tightening is also a classic blunder. You crank on that wrench, thinking ‘tighter is better,’ and you strip the threads, crack the material, or even pull the fastener right out. Screws should be snug, not tortured. You want them firmly seated and holding, but you don’t want to see the material around the screw start to distort or bow. This is especially true for fiberglass and composite materials, which can be surprisingly brittle when stressed incorrectly. The feel is important – a solid, firm stop is what you’re aiming for, not a point where you feel the material giving way.

People also make the mistake of not considering the length of the fastener. A screw that’s too short won’t get enough grip. A screw that’s too long might interfere with something inside your hull, like wiring, fuel lines, or storage compartments. Measure twice, cut once, as they say. Or, in this case, measure twice, drill once.
Real-World Use: When Your Trolley Gets Put to the Test
Let’s talk about what an anchor trolley actually does and why its attachment points are so vital. Imagine you’re out on a windy day, trying to anchor your kayak in a spot with a good fishing structure. The wind is pushing you one way, and the current is pulling you another. Without a trolley, you might end up anchored sideways, or worse, dragging because the anchor is pulling from the wrong angle relative to the forces acting on your boat.
With a trolley, you can adjust that pull point. If the wind picks up and starts pushing you around, you can slide the trolley forward to point your bow into the wind, stabilizing your position. If you want to fish a reef and the current is strong, you can slide the trolley back to get the anchor pulling directly against the current. This means your boat stays put, allowing you to focus on what you came to do, whether that’s fishing, relaxing, or just enjoying the view. It’s about control and stability.
Now, consider the forces involved. When your boat is broadside to a wave or a strong current, the anchor line is pulling at an angle. That angle creates use on your mounting points. It’s not just a straight pull; it’s a pulling force combined with a twisting or shearing force. If your mounting points are weak, that’s when you hear the dreaded ‘pop’ I mentioned earlier. I’ve seen people’s anchor trolleys rip out when they’ve hit a large wake, or when they’ve tried to use the trolley to pivot the boat in strong currents. These aren’t extreme conditions; these are the kinds of things an anchor trolley is supposed to help you manage.
I remember one trip to a lake known for its sudden wind squalls. I was anchored in a nice spot, but the wind suddenly shifted 180 degrees. Instead of fighting it, I adjusted the trolley. The reinforced mounting points held firm, and I was able to reposition the anchor within a minute, keeping my bow into the wind and my boat stable. The difference was stark compared to a buddy who had a cheaper setup; he was spinning in circles, struggling to keep his boat from drifting. His trolley mount eventually failed, and he had to motor back to shore to fix it. That’s the reality of what happens when you skimp on mounting hardware.

DIY Upgrades and Practical Tips
Let’s get practical. You’ve got your anchor trolley, and you’ve realized those stock screws are a joke. What can you do right now? The first and easiest upgrade is to simply buy better screws. Head to your local marine supply store or a good hardware store. Get some stainless steel pan-head or hex-head screws. For most kayaks and smaller boats, #10 x 1-1/4 inch or 1-1/2 inch stainless screws are a solid choice. If you’re screwing into wood, get screws with a good, coarse thread. For plastic, make sure the threads have enough depth to bite effectively.
If your trolley mounts have holes that are a bit too large for the screws you want to use, don’t just shove a bigger screw in. You can use a washer on either side to help spread the load and prevent the screw head from pulling through. For plastic kayaks, a large, thick plastic washer on the outside, combined with a stainless steel backing plate on the inside, is a fantastic combination. Some people even use rubber washers or gaskets between the mount and the hull to help seal the holes and absorb some vibration.
When installing, use a good marine-grade sealant like 3M 5200 or Sikaflex underneath the mounting bracket. This serves two purposes: it helps waterproof the holes, preventing water intrusion and rot (if you have wood), and it acts as an adhesive, giving you an extra layer of security. Apply it liberally but neatly. You can clean up the excess with mineral spirits before it cures. Let it cure fully, and you’ve got a much more solid attachment.
Consider reinforcing the mounting points. If your trolley has plastic mounting blocks, you can sometimes add small stainless steel plates to the underside of these blocks, effectively creating a stronger anchor point for the screws or bolts that attach the block to your boat. It’s a bit of extra work, but it adds significant strength. I did this on my old canoe, and it made a world of difference in how secure the whole system felt.
Finally, if you’re drilling holes through your hull, especially on a fiberglass or composite boat, consider using stainless steel threaded inserts. You drill a hole, tap in the insert, and then you can bolt directly into that insert. It’s a much cleaner and stronger solution than just relying on screws in the composite material itself, which can sometimes delaminate or crack over time. For many applications, this is as close to a permanent, rock-solid mounting solution as you can get without going full custom fabrication.
When Is It Okay to Just Use Screws?
If you have a very light-duty anchor trolley, for a tiny dinghy that will only ever be used in dead calm water, and you’re only anchoring in very shallow, protected bays, then maybe, just maybe, the screws that come with the kit might hold. But even then, I’d be nervous. For anything else – kayaks, Jon boats, sailboats, or anything that will encounter waves, wind, or current – you absolutely need to upgrade. The risk of failure is simply too high.
Final Verdict
So, to circle back to the main question: are screws enough for a n anchor trolley system? For the vast majority of users and applications, the answer is a definitive no. Those little screws provided in most kits are an invitation to failure. Think of them as placeholders, a suggestion of how to attach it, not the final solution.
Investing in proper marine-grade stainless steel fasteners, considering backing plates for important stress points, and using good quality sealants will save you a world of headache and potential disaster on the water. It’s a small cost for peace of mind and a system that actually works when you need it most.
Don’t be the person I’ve seen stranded, with a busted anchor trolley and a drifting boat. Take the extra step, upgrade those fasteners, and enjoy your time on the water knowing your anchor is securely held, no matter what nature throws at you.
