The ShoreMaster Tri-Toon Center Cradle adds a dedicated pair of bunks beneath the middle tube of a three-tube pontoon. The cradle pockets mount at the center of the front and rear lift rack beams, and the adjustable posts support two customer-supplied 2 x 6 boards. This part is an add-on, not a complete tritoon support package: the two outside tubes must already be supported by compatible pontoon cradles or another approved system.
What the Center Cradle Does
Supports the Third Tube
Adds front-and-rear center support beneath the tritoon’s middle tube.
Adjustable Post Height
The center posts slide within the cradle pockets so the bunk height can be matched to the outer support surfaces.
Centered Rack Placement
Front and rear pockets mount at the middle of the lift rack to align with the center pontoon tube.
Compatible Add-On Design
Works as part of a complete, model-specific tritoon support layout rather than as a standalone cradle.
What’s Included
- Two center-cradle pockets for the front and rear rack beams
- Two adjustable center-cradle posts
- Rack and bunk mounting hardware
- Part Number 1017068
Not Included
- Two 2 x 6 bunk boards
- Outer pontoon cradle brackets or rail system
- Boat lift, carpet or bunk covering
- Alternate center-cradle version required by some lift models
This Is Not a Standalone Tritoon Kit
Part 1017068 supports only the middle tube. A complete tritoon setup also needs approved support beneath both outside tubes, such as the compatible Pontoon Cradle set.
ShoreMaster uses different center-cradle assemblies for certain lift models and capacities. Confirm that part 1017068 matches the exact lift before ordering.
Setup Requirements
Match the Outer Bunk Height
Keep All Three Tubes Evenly Supported
- Install the outer pontoon support system first.
- Set the two center posts so the middle bunks meet the center tube at the correct height.
- Check the fully loaded boat for balanced contact before raising it completely.
Protect the Tube Surface
Two Customer-Supplied 2 x 6 Boards
- Use two straight, properly sized boards running front-to-back.
- Countersink the supplied carriage bolts so no fastener can contact the tube.
- Add an approved carpet or protective surface suitable for the boat and water conditions.
Installation Notes
Remove any rack component that conflicts with the center cradle, mount one pocket at the center of the front rack and one at the center of the rear rack, then install and level the posts.
The boat lift must have enough rated capacity for the tritoon’s fully loaded weight, including fuel, batteries, gear and accessories.
Frequently Asked Questions
Does this product support all three pontoon tubes?
No. It supports the center tube only. Separate approved support is required beneath both outside tubes.
Are the two center bunk boards included?
No. Two 2 x 6 boards and the protective bunk surface must be supplied separately.
Will part 1017068 fit every ShoreMaster pontoon lift?
No. ShoreMaster has used different center-cradle assemblies for different lift frames and capacities. Confirm the lift model and rack configuration before ordering this part number.
How should the center bunks be adjusted?
Set the center-post height so the middle tube is supported evenly with the two outside tubes. The final layout should keep the boat level and distribute weight according to the lift manufacturer’s guidance.
Can the center cradle increase my lift capacity?
No. Adding bunks or cradles does not increase the rated capacity of the lift. The fully loaded tritoon must remain within the lift’s approved capacity.
