Drotto Bunk Trailer Install

Video of the Drotto Bunk Trailer Install .

In this Drotto Bunk Trailer Install video we demonstrate how to install the Drotto boat latch on a bunk trailer. The Drotto boat latch is designed to replace the bow roller of your bunk trailer or roller trailer. There are many models and styles and variations of bow roller setups. Our Drotto boat latch is designed to replace your bow roller according to size. The 3″ model replaces your 3″ bow roller and the 3 3/4″ model is designed to replace a bow roller between 3 3/4″ and 4″ ( just add spacers or washers for larger rollers). The Drotto Bunk Trailer Install is simple in most cases. See below for further details on the Drotto Bunk Trailer Install process.

Step 1 

Locate the bow roller on your trailer. Here are only a few examples of bow roller setups below.

There are a number of different trailers. BUNK trailers and ROLLER trailers. The Drotto boat latch works on both styles of trailers. There are also a number of different bow rollers. The Drotto boat latch is designed to fit on the 3″, 3 3/4″ – 4″. refer to the “Drotto Boat Latch Sizes page” to learn how to measure your bow roller.

Step 2

Release the boat into the water. It is hard to move a boat on a bunk trailer, therefore we suggest simply launching the boat into the water.

Step 3 

Remove the single bolt holding the front roller on the trailer and remove the roller. Once roller is removed, replace it with the latch. Tighten the bolt snug, but not fully tight yet. Keep slightly loose so the latch can move just a little.

Step 4 

Drive the boat very slowly back up onto the trailer or crank the boat back onto the trailer with your winch. You will then hear the click. Once you hear the click you know the latch has secured and locked the boat to the trailer.

Step 5 

Simply snug up the bolt that secures the latch. You DO NOT want it extremely tight, It should be able to pivot slightly with the boat.

Double Roller Bow Stop Install

Here is a good visual if you have a double roller bow stop. In this version, simply remove the top roller, install the latch in place of the top roller and adjust the winch arm to line up the bow eye with the latching system. Another option is to remove the double bow stop completely and install the latch directly to the winch post.

Installed a drotto latch with roller for a Triton bass boat and love it! Highly recommended!!! Works perfectly for solo launch and recovery. You can also release the latch on dry land and launch normally with someone backing you in. Furthermore. The latch automatically adjusts so there is no problem on flat or steep ramps. Just wish I bought one sooner.

This is the best money I've spent on my boat. This makes loading so easy, especially when you fish alone. 2 of my friends have purchased one after see how it works.

Most unfortunately that the Drotto Boat Latch would not work on my 2021 Thunder Jet 185. The latch hook on my Boat is welded on and the Welding Design is not the typical hook. I can tell you that Darren the Owner work with me on the return and I was very pleased with his professionalism. So, so far as that is concerned he is a man of his word and that’s the reason for this review.

This device makes it easy to dock my boat on the trailer and I don’t have to get out and walk through knee deep water to latch the boat to the trailer winch. I just drive the boat onto the trailer and carefully power up the trailer until I feel/hear the latch click, then I get out of the boat and drive the trailer up the ramp, stop then on dry land I attach the winch snap and winch the boat tight for the drive home. My boat is 20 ft long and 5000 pounds and I can launch and load it by myself.

I have a saying, "nothing good happens at the put-in". Face it, at best it is a neutral event. I mostly launch/trailer alone, and now can do it with ease. I've had many witness me use the Drotto verbally respond from across the launch area; some even come to look at it. I recommend the Drotto to everyone. Follow the instructions. Call them if you need to. They are very kind and very good at what they do!
