The Single Vertical PVC Guide-On set makes loading a compatible boat lift easier in wind, current or limited visibility. Despite the word “Single” in the product name, the package includes a pair of guide-ons. Each aluminum support carries a capped 3-inch PVC post that is positioned just outside the boat’s widest rub-rail dimension, helping guide the watercraft into a repeatable centered position without intentionally rubbing against the hull.
Why Add Vertical PVC Guide-Ons?
Rub-Rail Guidance
The tall posts contact or visually track the boat near the rub rail rather than pressing against the finished hull.
Easier Centering
The pair provides a clear loading target and helps keep the boat aligned as the lift rack begins to rise.
Maintenance-Friendly Materials
Aluminum supports and replaceable PVC posts withstand waterfront exposure without carpet that can retain sand or debris.
Adjustable Placement
Position the guides to suit the boat width while maintaining clearance from lift braces, bunks and the canopy system.
Select the Version That Matches the Lift Rack
Straight Rack
Part Number 1021985
- Designed for compatible lifts with a straight rack beam.
- The support geometry positions the PVC posts with the intended outward angle on a straight rack.
- Includes the straight-rack weldments, PVC tubes and mounting hardware.
Bent / V-Rack
Part Number 1022109
- Designed for compatible bent or V-style lift racks.
- The angled support weldments keep the PVC posts upright when attached to the sloped rack.
- Select this version only after confirming the rack profile.
What’s Included
- Two rack-specific aluminum guide-on weldments
- Two 3-inch Schedule 40 PVC tubes, approximately 5 feet long, with caps
- U-bolts, backer plates and mounting hardware for the selected configuration
- One complete pair of guide-ons
Not Included
- Boat lift or bunks
- A second pair for front-and-rear guidance
- Custom adapters for unapproved rack sizes
Measure the Boat and Check Lift Clearance
- Measure the widest portion of the boat near the rub rail.
- Position the guide-ons slightly wider than that measurement so the boat can enter without binding.
- Center the pair equally from the middle of the lift rack.
- Cycle the empty lift and confirm the guides do not contact braces, bunks, canopy legs or other moving components.
Installation & Setup
The guide-on pair clamps to the lift rack using the supplied hardware. Final spacing depends on the boat width, rack width and nearby lift bracing.
Guide-ons help with alignment but do not replace correctly adjusted bunks, proper boat balance or safe lift operation.
Frequently Asked Questions
Why is the product called “Single” if it includes two guides?
“Single Vertical” distinguishes this design from ShoreMaster’s double-guide configuration. The product package contains one pair, or two vertical PVC guide-ons.
Should the PVC posts touch the boat hull?
They are intended to guide along the rub-rail area and help visually center the boat. Set the spacing so the posts do not bind against or continuously scrape the finished hull.
How do I choose straight rack or bent/V-rack?
Look at the front and rear lift rack beams where the guide-ons will mount. Select the straight-rack version for level straight rack tubes and the bent/V-rack version for the sloped rack geometry shown in the product images and instructions.
Can I install one pair at the front and another at the rear?
Yes, a second pair may be used when the lift has enough clearance and the manufacturer’s spacing requirements are met. Check all braces and canopy components through the full lift travel.
Will these fit every boat lift?
No. The clamp dimensions and weldment angles are designed for compatible ShoreMaster rack configurations. Confirm rack size and geometry before ordering for another lift brand or model.
