Drotto Latch 3 3/4″ With Roller

(17 customer reviews)

$299.99 $279.99

The 3 3/4″ Boat Latch with roller is designed to replace a 3-5/8 inch – 4 inch bow roller. With this Drotto boat latch model we added a bracket and roller to our existing 3 3/4″ model. The added bracket and roller helps the nose or bow of the boat roll off of the Drotto boat latch during launching. The roller is for boats that have a heavy nose. Typically with a heavy nose the bow of the boat drops during launching and the tip of the nose sometimes catches on the existing roller. The added roller keeps the tip of the nose from catching. The bracket and roller is needed for the boat latch system to work properly on trailer and boat setups that have this problem. Measure the inside width of the bow roller bracket on your trailer and make sure it is 3-5/8 inch – 4 inch wide before ordering. The Drotto boat latch is constructed of a very heavy gauge steel and weigh’s in at 14lbs. It’s sturdy. The 2 piece arm is included with purchase. The second piece is to extend the arm above the bow. The Drotto Boat Latch 3 3/4 with roller style only comes in a black powder coating. If the specs of your roller bracket width are 3″ – 3 3/8″ wide please refer to to 3 inch model.

**NOTE** This will not work on pontoons or flat front boats. This model is designed specifically for v front boats.

Drotto Latch Description

The Drotto Latch 3 3/4″ model w/ roller is very commonly used with Triton, Lund, Alumacraft, Crestliner, Smokercraft and many more. This Latch is recommended for boat – trailers that have a 3 5/8″ – 4″ roller and a heavy nose. The best way is to measure the inside width of the actual bracket the roller mounts inside.


installation of the Drotto Latch 3 3/4″ model w roller is a simple one bolt installation. First back your boat and trailer into the water. Lower the trailer into the water until the boat starts to float. Then once your boat is floating, you may let out a little slack from the strap while keeping the safety chain attached. Push the boat back into the water roughly 8 inches to give yourself room to work. Now that you have room, remove the bolt from your front roller on your trailer. Now take the roller off. Once removed place the Drotto latch in its place and place the bolt through one of the 2 mounting holes. (typically the hole closest to the jaws is best). After the bolt is installed tip the latch to an angle that very closely matches the angle of the boat. Snug the bolt up just enough so that it is not flopping around. Now using your crank the boat in until you hear the Drotto latch click, Now snug up the mounting bolt. This should be snug enough that the Drotto latch does not flop around, but you also do not want it real tight. It is best that it can move. Now that the latch is secure you can install the release arm. Slide the thick spacer onto the side of the shaft you want the release arm to be on. Next slide the release arm on then install the coder pin to keep the Drotto handle secure. You are all set.

    One bolt does not hold device. Device moves. Nut does not hold tight.

      Thanks for the feedback Edward. Just note you typically want the latch to swivel a little. The latch should not be really tight.

    When it worked it was great. It has stopped working and I’m back to crawling over the nose to secure the winch. In it’s defense it may just need some lube as its been a few years with no maintenance.

    Everyone unloading or loading a boat by themselves should have one of these. Back the boat down, climb in, pull the rope…and “clack” the boat slides off the trailer into the water. Same thing coming in…line the boat up, give it some throttle, up the bunk boards and “clack”, your latched. Shut the motor down, and pull the boat out. Super easy!!!

  8. William Hornsey

    Just purchased. Have loaded and unloaded the boat three times. Had to adjust the roller wheel. So far the product works as advertised. I am 66 years old and it keeps me from hanging over the bow to latch the boat.

  9. Mike Beus

    Works well for someone that fishes by them self. It was a little more difficult to install due to my trailer mount having a 4 inch opening. Had to place washers to make of the space. Everything when well with the mounting. Its has made it much easiler to load the boat when the wind is blowing.

    I had hard time cranking up my 217 gl Lund With this I simply drive up and it latches. Also makes unloading much easier I unhook winch and safety strap back in and pull lever when I’m already tied off to dock. I will never not have one of these. Also bought my 71 year old father one and he loves it! It will push boat back couple inches on trailer so trim tabs need to pushed out more

  11. Donald Lundin

    Easy to install works as advertised so far so good!

  12. Ken Christie

    Installed on a Triton 189 bass boat and it works great. Have used all season and never a problem. Easy to use, engages every time.

  13. Brett Humphus

    I mostly fish alone, which means I launch and load my 23′ bay boat alone. This product has been an absolute blessing since installation! Even with a custom built trailer, with my boat being a Vhull there’s no way to prevent slide-back when loading. This always caused me to have to get wet or strain my back bending and stretching out over the bow to winch it in a foot or so. With the Drotto Latch all I have to do is drive up and it locks in, I step out onto the dock and get in the truck and pull out of the ramp. That simple. Highly Recommend!

  14. Ken

    Works as advertised, I wait 10-15 minutes for other people loading and unloading there boat usual way. I am in or out of water in approximately a minute or two and that’s because I let motor warm up 30 seconds when launching. People just watch with amazement at ramp. Great product, no more wet feet and hand cranking! With all the high water at boat ramps took couple of times to find trailer depth for my bunk trailer but now it works great every time. Save time, wet feet and frustration.

  15. Bill Chapman

    Only been able to use it 2 or 3 times but it seems to work properly and makes it much easier to launch and retrieve boat. Wish I had this years ago.

  16. Bob Larson

    Had watched other boat owners load using the Drotto and was impressed. Don’t know why I waited so long to add one to my own trailer. I ordered the roller version and probably would not have had to, doesn’t interfere with operation just don’t believe it was needed on my 2015 – 1900 Tyee w/bunk trailer. Took less than 5 minutes to install. Wish I had put the Drotto on years ago!

  17. Jon Clouse

    After buying a longer bolt to fit the trailer for my 18’ Lund, the device works well. Every ramp is a different angle and you have to learn how far to back in trailer for each ramp.
