[PSUBS-MAILIST] Trailer

[Dan H.]

Scott,

My extension is 19 feet and I get out about forty feet from shore when in the launch setup with the truck tires in a few inches of water.

  Dan
  How long is it when it is fully extended?
  Thanks,

  Scott,

  I used 2-1/2 inch schedule 40 pipe for the outer tube and 2" schedule 40 pipe for the inner tube.  2-1/2 inch pipe actually measures about 2-7/8 inch OD. and like wise, 2" in near 2-3/8 OD.

  If I were making another one I would jump up one size for each.  3" pipe for the outer and 2-1/2 inch for the inner.  
  It's a bit more weight but would allow you to actually push back a little if your trailer dropped in a hole while backing in.

    I like the ease of making the bar, but backing up a double trailer is pretty difficult. They way they do it in the video is on the ramp, chalking the tires and attaching a tow strap in case it started to roll down the ramp. I currently have been launching my sub with a tow bar similar to this from my parents yacht club. I think the long and the short of it is the tow bar is a better option due to ease of construction and the ability to make steeper ramps work.
    Any idea on the size of metal tubing used for Dans design?
    Thanks,
    Scott Waters

      Hi Scott, 


      Actually Dan H's solution is telescoping as well, and I like it better than mine, particularly if your trailer is already built as you will not need to change it. See this video, starting at 0:38.

      Best,

        Hi Scott,
        Have a look at the 3rd picture from the bottom here of Dan H's trailer.  Im going to make a very similar one out of a scaffolding pole.  Im not going to bother making it telescopic, just carry it strapped to the trailer bed and attach it when needed.

          If you use the telescoping idea, how big of square tubing do you need to do a 20' stretch?

          Hi Scott,
          That is a question with no right answer.  It totally depends on your boat ramps.  If I understand you, your choosing between a extension pole between truck and trailer and a telescopic reach.  If your boat ramps have a sharp angle at the crest then a telescopic reach may drag on the ground.  I like the telescopic reach idea because you can just pull a pin then drive ahead until the reach is extended.  Put the pin back in the new spot and your away.  If you have limited help that is the way to go.

          I am working on modifying my trailer so I can launch my sub myself. I have 2 ideas. One is the conventional idea of havinga second tounge extension trailer so I can get the length to launch the boat. The second is to have a long touge that replaces the hitch and the long tounge has a hitch on it? Any reccomendations?
          Thanks,
