    I was adjusting the positioning of my hull on the trailer which entailed moving the winch stand and moving the hull forward to get more of the stern on the bunks.

    I discovered that when I pushed the hull back off the winch roller that it popped up about an inch or so.This indicated to me that the hull was under downward pressure when cinched up tight.
    Not good.

    Also, I was concerned about not having any hull support for the front half of the hull.It may not be an issue but I did not care for it because all I could think of was .. I am putting a "hook in the hull" .

    I came up w/ two  low dollar solutions.

    I shimmed the winch up about a 1/4" which enabled the bow ring/ hull to be  pulled and cinched in at almost a perfect horizontal which alleviated the downward pressure.

    Then I cut a brace out of 2x4 pt and and screwed it from underneath the forward most crossmember that supports the trailer tongue extension(where the wiring goes into the boxtube). I carpeted the brace w/ 4-5 layers on the top edge where the hull will rest.This now gives the hull support in the front and the carpet provides some cushioning on the brace.

    All this took less than an hour. It helps to have a table saw but u could use a skillsaw to get it done. The table saw makes up for my sawing skills or lack there of. ;).

    I am  a happy camper now!

    This happens all too often with trailers and hulls.
    If the winch cable/strap isn't pulling straight thorugh the bow eye
    and parallel with the keel line, it can make it difficult to winch up
    a hull at the ramp and long term it can put a "hog" in your hull.
    Even brand new trailer and hull combinations, straight from the dealer,
    will suffer from this syndrome. Minimum wage labor only does what
    they're told, not what needs to be done for a properly rigged trailer.

    Another problem [smiley=1-doh.gif]

    I discovered that there is a gap between the inside edge of the left bunk and the hull. A little investigation revealed a 10 degree tilt on the rear support bracket and 5 degree of tilt on the remaining brackets. This explains why every time I loaded the boat the rt.skeg was up against the rt.bunk [smiley=1-smack-myself.gif]

    The rt. side brackets are at zero degrees.

    So now I need to shim the bunk at the brackets to get to zero degrees.

    The bracket width is just shy of 4"....to any math brains what thickness of shim do I need to start with to get to 0 degrees on the bunk????

    Can u tell the wind is blowing!!!!!

    tangent of 10 degrees times 4 inches equals about 11/16 ths of an inch

    tangent of 5 degrees times 4 inches equals about 3/8 ths of an inch
