Thanks - I think both trailer designs have individual merit. The real advantage as we've seen, is having the saddle/cart serve double duty. I can't use my rear saddle as a beach cart as it wouldn't get past my stern roller or the end of my pvc mast carrier; that's why I mounted it up front.
Your trailer being lower to the ground than my Trailex SUT 350-S, allows you to do what you've done which is really terrific. Mine allows me to have a bit more support, the carrier, and the stern roller, which does come in pretty handy sometimes.
However because of the height, when I begin to slide my TI off my trailer I first have to place a small wheel cart at the stern so it doesn't hit the ground, then put my Appel Cart underneath the boat (up towards the balance point near the rear crossbar). As I continue pushing the boat off the trailer and it begins to level out, I go back and remove the small cart and use just my cart to roll away. From watching your video I can tell you that you're definitely faster than me
, but that's okay.
I think there's a design out there that would incorporate all of this, we'll just have to wait and see.
Enjoy your boat and thanks for sharing your new trailer design.
