I have my partner dunk the trailer to soak the bunks, then pull out ( like BCB said) until the first few inches of the outer bunks are out of the water. I slowly cruise up to the trailer and the boat will straighten and settle in the bunks. Then throttle up till the bow eye makes contact. If the bunks are dry it takes too much of a push to get there. If it wont push all the way up – I have the driver back up a little while I throttle up. Its better to be too shallow as too deep.
