does your double v bow support pivot at the center? I have a double support as well, mine will do the same thing, (bow eye hangs up on the bottom support) I finally  figured out to rotate the center supports clockwise so the uber v support is now in front of the bottom one.  that way the boat comes in, clears that lower eye and then the boat makes contact with the upper support first and pulls the supports back into position as the boat loads all the way up.
