An ice Shove by any name …
Ice Shove, Ice Heave, Ice Surge, or Ice Tsunami, no matter what you call it, they all refer to the same natural phenomena.
First, you need to understand how a pressure ridge forms so please follow this link to this article: https://wisconsinpws.com/ice-pressure-ridge/
The pressure ridge is the usual predecessor of an ice shove.
Having read the article, we need to talk very briefly about the terminology of a pressure ridge.
Sample Pressure Ridge
From the previous article, you can see the “rubble” forming the “Keel” of the pressure ridge. After the Keel forms the “Sail” forms above the surface of the ice. When the next strong wind comes along the “sail” will begin pushing against the shore ice. Eventually, some of it will begin to climb over the shore ice and form an ice shove.
When do Ice shoves typically occur?
Ice shoves normally happen during a spell of warmer weather. However, the shove may happen anytime the ice is weakened and then exposed to strong winds.
A shove is more likely to occur the longer the ice is exposed to the winds. The most common time of the year to see this phenomenon is late February and into March although January is not unheard of if a thaw occurs.
The shove occurs when strong winds rapidly push free-floating ice towards or along the shore. Strong winds over time drive areas of ice onshore. As these moving masses of ice travel towards the shoreline, they begin piling up when they encounter resistance from the shoreline or other obstacles. The resulting shove can reach heights of up to 50 feet.

What will an ice shove do to my property?
An ice shove has tremendous power and have been known to push houses off their foundations and uproot large trees and crush seawalls.
Shoreline barriers like trees, seawalls and shallow cliffs do not present any challenge to an ice shove. The ice simply piles up until it flows over the object or simply crushes it. The shove could continue on its journey as long as the winds continue. This depends on the force of the wind and the strength of the ice. One or two properties may be affected while the adjoining properties see no movement at all.

How do I protect my property?
There is only one thing that you can do – move your waterfront equipment far enough away that the ice normally will not get to it. In doubt? Watch what your neighbors do in Fall. If they have been there for any length of time they know how far back to go to protect their equipment in a normal year. Our crews remove equipment in Fall and have a good idea where it has to go also.

Lift Removal to escape an ice shove
With little or no shoreline, here’s an example of what PWS does to prevent damage to your equipment. The lift and dock had to be raised to the top of a ledge to avoid damage.
How big are Ice Shoves?
Ice Shoves sometimes affect a small area of shoreline all the way up to vast distances. This ice shove affected just one property while the neighbors had no damage.

What causes an Ice Pressure Ridge?
An ice pressure ridge results from a change in temperature which causes the ice to crack.
Ice Pressure Ridge – Door County
This forms a floating sheet of ice. When an area of open water is present the sheet of ice is able to move freely.
Think of an ice cube when you first put it into a glass of water. When exposed to the warmer water the ice cracks at the weakest part.
Where Does the Pressure Ridge Start?
A pressure ridge usually starts a few hundred feet off the shoreline in what would be 2-3′ of water in the summer. Up to this point, the ice is anchored to the bottom of the lake. The ice near the shore remains very stable and does not move from the shoreline.
Water begins at this point under the ice. The water gets deeper as you go out. Much like an ice cube, the ice will “crack” when exposed to pressure from winds or warmer temperatures.
If you have ever been on or near the ice in winter, you have heard the ice “crack”. The wind is generally blowing at these times or the ice may have been exposed to warmer temperatures. The ice builds up pressure at the open-water mark. The ice separates and “cracks”. This sound can travel for miles.
The pressure ridge may form anywhere there is thin or weak ice.

How does the Ice Pressure Ridge form?
With the ice near the shore securely anchored to the shoreline and the bottom, the floating ice on the outer side of the crack moves away from or along the shore with the wind. If the direction of the winds changes it moves
With the ice at the shore anchored to the shoreline, the floating ice on the outer side of the crack moves away from or along the shore with the wind. When the direction of the winds changes it moves back to the joint or along the joint again.
When the floating ice hits the stationary ice on the shore, pressure builds up and crushes the edges into pieces called “rubble”.
Some of the “rubble” sinks to the bottom due to weak ice under the top layer. This rubble forms the “keel” of an ice pressure ridge. The loose “rubble” continues to accumulate under the main shelf of ice until it hits the lake bottom.
When the “rubble” hits the bottom there’s no place for the “rubble” to go – except vertically. Now the accumulating rubble forms the “sail” on the upper part of the pressure ridge. The “sail” can be anywhere from inches high to 50 feet high depending on the winds and the strength or weakness of the ice.
Ice Pressure Ridge
When the “rubble” hits the bottom there’s no place for additional “rubble” to go – except vertically. Now the accumulating rubble forms the “sail” portion or upper part of the ice pressure ridge. The “sail” can be anywhere from inches high to 40 feet high depending on the winds and the strength or weakness of the ice.
How fast does the Pressure Ridge form?
A pressure ridge usually forms rapidly when the winds are blowing strong and steady. You need to be especially careful when approaching the pressure ridge because you don’t know how much solid ice remains.
Since the “rubble” below has been exposed to non-freezing temperatures, it starts to melt away. This results in a weak and fluctuating joint at the surface. The area around the ice ridge can be very dangerous.
Warning – Thin Ice
Are there other signs of weak ice?
Slow melting ice will result in dark areas which means the water on top and below the ice is melting the ice away. Never go on this type of ice as it is very weak. Be careful around pressure ridges, they indicate the presence of weak ice.

Jet Ski Lift Platform
A Jet Ski Lift platform is the latest development of Pier & Waterfront Solutions. These stainless steel loading platforms are made exclusively for the ShoreMaster SM 1064 and SM 1264 Jet Ski Lifts by PWS.
Jet Ski Lift Platform
The jet ski Lift platform kit consists of a stainless steel, perforated platform that mounts securely to the lift rack.
- No need to drill holes and risk damage to the cables inside.
- The platform never rots.
- Simple to install – one 9/16” wrench is all you need.
- Stainless steel platforms provide a stable loading or working platform.
- The walk platform allows easy access to both sides of the Jet Ski – in or out of the water.
Additional benefits
- It allows you to put a cover on your Jet Ski while high and dry.
- Why scramble over your jet ski to put a cover on?
- No more getting tossed around by waves while trying to work.
- No more trying to stand on the lift rack and risk falling or injury.
Imagine being able to service your jet ski without having to stand in the water. Now you have a loading platform to set your equipment on when working on the engine or re-fueling your unit. You can do all kinds of work and stay dry.
How About another Great Idea?
Also offered by Pier & Waterfront Solutions – a Jet Ski winch extension post kit.
The extension post kit allows you to move the winch higher on your ShoreMaster lift post. Now you have better access to the wheel from the dock – even if the dock is above the lift wheel. No need to lie on the dock in order to reach the wheel.

Boat Lift Canopy Maintenance
Boat lift canopy Care will provide you with years of service, if properly used and maintained.
Proper maintenance is important in the Fall
Boat Lift Canopy care is an important step to extending the life of your canopy. As the air gets cooler and the days shorter, the leaves begin to turn colors. You know what’s ahead. You can hope for more sunny, warm days but we know that nature is in total control.
Fall Foliage
We also know there are some things we need to do to maintain our docks, boat lifts and accessories. It’s more than simply moving the equipment up on the shore. Protecting the equipment from the ice is just the beginning of what should be done.
Note – It should be pointed out that while PWS does remove and store your boat canopy in your designated spot as part of our removal service, canopy cleaning is not part of the service due to the length of time it takes to clean and thoroughly dry the cover as explained below. The process can take a full day to be done properly. After cleaning the canopy it must be thoroughly dried before storage.
What steps do I need to follow with a Boat Lift Canopy?
Follow these simple rules to get the maximum life from your canopy.
1. Always avoid allowing water to puddle on the canopy for extended periods of time during the season. Water, excessive bird droppings and dirt cause discoloration.
2. It’s important to keep the canopy free of battery acid and tree sap. These may corrode and eat holes in the canopy.
3. Always fold and store the canopy ONLY when completely dry. Wet or damp vinyl will discolor and form mold/mildew if stored in that condition. Storage in a warm, dry location will extend the life of your canopy.
4. If stored in a bag make sure it is breathable. Do not use a plastic bag. Moisture will be trapped inside and mold or rotting will occur.
5. DO NOT use chemicals or abrasives to clean a boat lift canopy. This could damage the vinyl. Use a soft cloth, mild dish soap (like Ivory) and water for best results.
6. Of course, Do Not get too aggressive when cleaning bird droppings from the vinyl cover. You may wear the protective finish off in that area or tear the vinyl.
7. If weather is threatening, keep the boat on the lift. Without the weight of the boat to hold it down the lift could be flipped over by the canopy.
8. The boat lift canopy must be removed when taking the boat lift out of the water for any reason. Failure to do so could result in wind damage to the canopy, boat lift and surrounding equipment.
9. Additionally make sure the boat lift canopy is completely dry before storing it. This will prevent mold and mildew from ruining the canopy. Those autumn leaves are beautiful but if left wrapped in your canopy they will permanently discolor your canopy cover.
CAUTION: A Vinyl canopy is removed by detaching hooks. Stretching and removing bungee cords requires strength and proper balance. DO NOT let release the bungee cord when under tension. An eye injury or other bodily injury could occur. ALWAYS wear safety glasses and the proper protective clothing.
Boat Canopy Care
Boat Lift Canopy cleaning
The cleaning and proper storage of your boat canopy requires some basic supplies and steps to ensure the longevity of your cover.
The first step is to ensure that any product that you use is safe for your canopy material. If you must use a chemical to clean your canopy, be sure it does not contain any ingredients that will stain, corrode, or otherwise damage the material.
The next step is to remove the canopy from the lift. Once removed, spread the canopy out on a flat clean surface – grass is fine. You need to avoid damp or freshly mowed areas as this may increase the work you end up doing. (Remember to remove any cut grass, etc from the bottom of the canopy before folding for storage
PREFERRED METHOD; Use a gentle dish detergent and warm, soapy water and a soft bristled brush to gently clean the surface. Rinse well and allow the boat canopy to dry thoroughly.
Boat Lift Canopy Storage
After thoughtfully drying it, store the boat canopy by carefully folding the canopy in on itself several times until it resembles a strip 18”-24” wide and then roll the canopy into a roll that is manageable. Many canopies will come with their own storage bag but if yours did not, take care not to store the canopy in a plastic or otherwise un-breathable material. Remember – It MUST breathe through the winter.
DO NOT roll the canopy cover so tight that it can not breathe and DO NOT put a sharp crease in the material. The canopy should be allowed to “rest” in a protective bag or box that allows for proper air movement. If the bag does not allow the canopy to breathe, moisture could accumulate and promote molds and mildew in the off season, ultimately making your canopy’s life-span shorter.
Do not store on the floor where moisture can accumulate under the bag or box.
You should avoid binding the boat canopy for storage and never use duct tape to keep the canopy bundle together as the glues used are difficult to remove. Binding the canopy for long periods could promote intense creasing that may eventually lead to splitting of the canvas.
The stitching and seams that hold your canopy together should be kept as clean and dry as possible to avoid the failure of these areas from exposure to moisture, mold and dry-rot as the years roll by.
Prevent small animals (squirrels and mice) from getting into the rolled material. They can cause stains and premature product failure if allowed to set up housekeeping in your cover.
What about the Canopy Hardware?
Bungees, springs, cords, straps, etc., should be stored in a SEPARATE bag and kept with the canopy to avoid misplacement of the hardware and unintended damage to the canopy by these items. If rolled into the fabric layers for storage, moving the bundle can wear through the fabric and accidentally punch holes in it.

Remove the Jet Ski Lift from the water
Jet ski lifts need to be removed from the water for the winter in Northern climates to prevent major damage.
Dock-mounted lifts that rotate over the dock should be stored over the dock and secured in case of storms. The Jet ski itself should NEVER be stored on the lift for the winter. Ice accumulations can severely damage the lift. Non-rotating or free standing lifts need to be removed from the water
Jet Ski Lifts- simple yearly Maintenance
Jet ski lifts require simple winterizing maintenance at the end of the boating season in order to prolong it’s life.
ShoreMaster Cantilever Jet Ski Lift
Here are some things you should do:
- Inspect the jet ski lift at the end of the season for worn parts, frayed cables (extremely important), loose bolts, etc
- For electric powered jet ski lifts, remove the motor and store it inside of a building or relieve the tension on the bungee cords, if so equipped.
- If the water will be freezing during the winter, move the lift to dry land
- Check bearings for noise and proper operation
- Make sure there is no vegetation or sand in the rack frames
- Check all pulleys and other wearable parts for damage. On older models, with plastic pulleys, rotate the pulleys by hand to insure none of the pulley edges are broken. In general, these must be replaced.
- Ensure that the lift moves freely up & down without binding or straining. A general rule when lowering the rack is to maintain downward pressure on the rack.
- For electric jet ski lifts, remove the motor and store it out of the weather or, at a minimum, relieve the tension on the bungee cords, if so equipped.
- All cables should have a quick spray of penetrating oil applied to them, including on the cable wrapped around the winch drum. However, DO NOT APPLY any oil inside the winch mechanism itself.
- Is it time to replace the carpet on the lift bunks or should you consider replacing them with maintenance-free vinyl bunks?
When should I consider these adjustments
Fall or early Spring is a good time to order replacement parts for your jet ski lift. Call or email Pier & Waterfront Solutions for replacement parts. When spring arrives the lift manufacturers have very busy shipping schedules and parts can take longer to get.
Be ready for summer fun.
Enjoy the summer on your jet ski
