How to Add Length to a Boat Trailer Tongue to Avoid Backing Vehicle Into the Water
Updated 12/15/2025 | Published 11/01/2024
Question:
I have a small boat trailer I can send pics that I want to install an extender to the trailer tongue so I can launch the boat without submerging the back end of the car. I need about a 5’ extension The tongue is galvanized 3”X3” . Any suggestions?

Hey Robert, thanks for reaching out!
The best options we have to add length to your trailer tongue is with the Fulton Fold-Away Coupler Hinge which comes with Weld-On # FHDPW330300 and Bolt-On # FHDPB330301 installations. These have a 5,000 lb max weight rating, but that decreases the more length you add.
Aside from this we have longer ball mounts like the Hidden Hitch Ball Mount # 80232 you purchased that can also help add more length to your setup.
