Thanks! Honestly it wasn't that hard to build. I did the whole thing in one day. I ordered the metal pre-cut and had it delivered UPS. I did trim a few of the cross braces with an angle grinder, but really didn't have to. I used a big'ol rivet tool from Northern Tool and an old-school corded drill to put it all together. The only hiccup was burning through 4 drill bits. (Although I killed one of them by dropping the drill. ) - Total cost$220 for aluminum parts including shipping, $35 for rivets, $20 for drill bits, $20 for U bolts, $3 for pool noodles. All in for just under $300. I'll probably order some nice rack pads to replace the noodles in the future.That is very nice! I'm jealous...
I agree it would be easier to get up/down that way, but I thought the prevailing sunfish wisdom was to trailer upside down whenever possible?Looks great! You might consider bunks for the top rack also, one less flip to make.
Resurrecting an old thread. I really like the double stack and need it now with being a two boat familyI need to figure our if I can modify mine to hold the double stack.
Don’t tell that to Dynamic or Seitech! I don’t think I’d rivet mine, but aluminum is widely used in small boat trailer racks.Welded or riveted, aluminum is poorly suited to the flexing it would receive as a rack.

Due to aluminum's poor resistance to flex at joints, riveting or welding aluminum would start cracking right away. If I were to stack nearly 500 ponds of trailered Sunfish on aluminum racks, I'd secure the corners with polycarbonate clamps, as Seitech has.Don’t tell that to Dynamic or Seitech!

It's been 4 years since I built mine and the whole rig is holding up really well. I used heavy aircraft grade aluminum with lots of support and high quality titanium rivets. It does flex some but I've never had any issues. A couple of years ago I modified the bottom bunks to hold the boat on a sietech dolly. That was a big improvement.
I'm actually a big fan of aluminum, especially when it's used with curved surfaces.Welded or riveted, aluminum is poorly suited to the flexing it would receive as a rack. While I personally don't have a need for such double-trailers, I'd suggest a look—from the side—as someone else drives the trailer slowly over a speed bump..
