Sonar Tilt System

This is designed to ship Sonars in a container 7 feet 8-1/2 inches wide and 8 feet 5 inches high

This should give you the Sonar on the trailer 7 feet 7-1/2 width, 8 feet 1 inch height. For standard containers you have to drop the axles so to loose 6 inches in height.

Step one

Secure the twin channel piece to the trailer, either through bolt or with square pipe clamps with the inner piece up next to the normal Channel (photo 7)

Step Two

Lift the boat clear of the trailer. If you do not have a hoist that moves sideways then position the trailer one foot inside of vertical lift and control the boat as it lifts since it will swing out.

Step Three

Remove the middle and aft left side screw jack stand remove the adjusting nuts, put the adjusting nuts on the new screw jacks, these as two feet long and will now be left for both boat positions. Remove the right side forward and middle screw jacks, these will be stored until the boat is reset back to upright. Replace the right screw jacks with the two screw jacks from the left, these will sit right down on the support, use one washer to spread the load.

Step Four

Set the boat down with the keel on the outer channel and tilt to the right until load is on the right supports, adjust right aft screw jack until load is on all right supports. Adjust left screw jacks until support is on hull firmly. Photos 1,2,3,4,

Step Five

Attach keel/hull frame to inner channel and adjust so there is load on the frame. This is only to keep the boat from moving at the hull/keel area and is a support for that area. Photos 5 and 6

Step Six

Double check that all supports are under load and secure the boat to the trailer with straps. There is a diagonal behind the keel and suggest padding that and securing the keel from shifting fore and aft.

Step Seven

Loading. Deflate right tire to about 15 psi. this will give extra tilt and hence less width. Move into container, position, and block trailer so the trailer frame is solid to keep from bouncing. Secure to container. Ship mast hanging from overhead.

This system is designed for tilt to the right, if needed to tilt the other way reverse screw jacks and double channel
