Steel bunks insted wood...

Yes that would work but the wood is more forgiving.

One of my lifts has more wood than it should on the bunks and it floated so I took a 3 foot long 4 inch PVC pipe capped one end filled it with concrete capped the other end and hung it on the lift. Problem solved

Let the air out of the tires... problem solved!

It is one of the true advantages of having a tandem/ large cap axle trailer over a triple, along with paying less for tolls, getting better gas mileage..etc.

This won't work. It will only add weight when the trailer is on land, not underwater.

See my posts from the other linked thread. My techniques worked.

Also, make sure you pop a hole in the top of the fenders. They trap air and also become buoyant.

By his post it was obvious he was joking

LOL. I didn't catch that.

You just have to watch when you refill the tires with air. You have to do it with the boat off of the trailer. If the boat is on the trailer, then all that weight will throw off the tire pressure reading.
