I'll just give you the answer that I give most of our customers that ask if a given boat / trailer will fit in their garage. "If you back it in fast enough the first time..."

Probably a stupid question Nate but are you trimming the outdrives down? Had to do that with mine when I kept it on the trailer. Dropped over a foot off of the overall lenght.

What type of construction is the existing trailer?

I'd look into making it so the tongue could be slid back and locked into position. Construct it much like the receiver for your truck hitch... just longer and with a couple of real beefy pins.

I manufacture large renewable energy trailers (mild steel) that regularly exceed 10k lbs. We often build trailers with either removable or swinging tongues for security or space concerns. As someone stated earlier, properly engineered anything is possible. I would look into either a telescoping tongue or possibly a sleeved tongue that you could remove. Just remember, overbuilding is NOT engineering.

I have seen them on 34' boats, but it was a removeable tounge, it had to be bolted on and off, the dealer recomended you use an impact to tighten the six bolts. I think Ziemen out of Arizona made it.

I am in heavy highway construction and all of our message board trailers and many larger trailers have removable tongues for anti-theft. They are heavy duty steel square box sleeves with two pins holding them in. They work on the same principle as a truck hitch into a receiver where the sleeve supports the weight and the pins just keep it in place.

I saw this pic on another site and wasnt sure the purpose of this type of trailer.

Yes, that's a very light duty version of what's being kicked around here.

Hey Nate, I say try it see what happens.

This is exactly what I was thinking. Everyone is saying it isn't going to be safe to have something fold away or removable but that is exactly what is on the back of all of our vehicles. the whole system rides on a single pin for most of us. so yes, it can be done, and it can't be that hard.
