i am a newbie to boats as i have purchased my first boat about a month ago. After doing some work on it and making sure that it was mechanically sound for her test run it was finally time to put her on the water. So i got to the ramp, unhook the transom straps put the plug in and backed her down the ramp to the point where inoticed it was floating and stopped. The prob that i had was i could not get it off the trailer. I noticed that it was hung up on the bow eye and the bow stop. The eye was on top and after pushing on the boat kind of firmly then it slid off the stop and went on into the water. When we went to retreive it, i put the trailer in about as far as it was wehn i launched it and floated it up over half way used the winch and pulled her on and straitend it out as it slid up on the bunks, but when it came up to the bow stop the wench and stop was about 18 inches to low so we made the adjustment and slid the stop and winch down. When we got back to the house i looked at it and noticed that the boat had popped back up to where it normally was. First question is why did it get hung up on the eye?? Am i putting the trailer in to deep during the launch and retrieve is that the cause of my issues?? if so how far do i need to put the trailer in the water?? i for got details on the boat it is a 17ft deck boat with a 3.0 mercruiser and alpha 1 and many thanks in advance
