Make Boating Easy

Getting out on the water shouldn’t be complicated – and, with a SeaPen, it isn’t.

The easiest way to keep your boat dry and free from marine growth.

No lifting or lowering your vessel.

No towing or trailers.

Just one remote-operated rear gate that lets you launch and dock with a single button click.

It’s as easy as parking your car in the garage.

Why Dry-Dock With the SeaPen?

Dry-Dock at Water Level

The SeaPen cradles your vessel at water level – all the benefits of dry docking, without lifting or spoiling your view.

Save Money and Protect Your Asset

Save money on ongoing boat maintenance and antifouling costs, while also reducing fuel consumption due to a clean hull. With your boat stored out of the water, you'll enjoy a higher resale value, and the SeaPen itself is a valuable asset that can be sold.

Safe and Easy to Use

The SeaPen acts like a catcher, helping you dock your boat, even when you are on your own. Easy perimeter access around your boat means you can easily put your covers on and clean your boat.

How the SeaPen Works

simple

Easier to Dock.
Easier to Boat.

You don’t need antifoul to protect against marine growth.

And you don’t need a boat lift to keep your hull dry.

Because the SeaPen does both – a water-level dry dock that uses a proprietary rope mat layering that allows for drainage and air ventilation between your boats hull and the skin of the SeaPen so that your boat becomes completely dry.

Using the remote, push the down button to open the rear gate, dock your vessel, raise with the up button, and let the automatic bilge pump drain the water away.

The water will drain out of the SeaPen and it will shrink wrap the hull, keeping your boat out of the water.

It’s the simplest way to keep your vessel free of marine growth and performing at its best.

Improve Your Vessel’s Performance

Antifoul is toxic, expensive, and time-consuming to apply.

It’s also a performance inhibitor that adds extra drag to your vessel.

Ablative antifoul (the kind used on most recreational vessels) can decrease your speed by 3–5 knots and increase fuel burn.

Over time, as you apply additional coats, you’ll see even greater drops in performance – worsened by biofouling that continues to grow on antifouled surfaces.

Dry-docking in a SeaPen eliminates the need for antifoul, keeping your vessel operating at its best.

A 2023 DOCKPRO survey of than 100 customers showed that the average boat owner used their vessel 32 times a year with on-water storage

compared to 11 times a year when it’s on a trailer.

Less Maintenance.
Better Resale Value.

Buying a SeaPen is an investment that pays for itself.

Between antifouling, lifting, cleaning, and stripping, a 9-metre vessel stored in a wet slip costs around AU$25,000 to maintain over a 5-year period.

Storing that vessel in SeaPen costs roughly the same – but with less salt damage, less time spent on maintenance, and a cleaner hull.

It’s why vessels stored in SeaPens can be resold for 6–8% more than comparable vessels stored wet, and why buyers often choose to purchase vessel and SeaPen together.

If you’re serious about maintaining your boat’s value, dry-docking with a SeaPen just makes sense.

The Key to an Easier & Better Boating Experience

Better for You

Dry-docking your vessel means you don’t have to spend time applying and stripping antifoul or towing your vessel to the water.

That equals more time out on the water for you and your loved ones.

You’ll also be able to get a higher price when you sell a dry-docked vessel – more funds for your next adventure.

The SeaPen also acts like a catcher, helping you dock your boat, even when you are on your own.

Easy perimeter access around your boat means you can easily put your covers on and clean your boat.

Better for Your Boat

Both ablative and hard antifouls can affect your vessel’s performance, increasing drag and fuel consumption.

Antifoul also doesn’t prevent salt damage, growth on your motors and props, or scrapes and bumps from other boats – which can all be avoided through dry-docking.

Better for the Environment

Most antifouls are biocidal, which means they work by poisoning barnacles, algae, and other marine growth.

Over time, that poison leaches into the surrounding water, which can kill sea life (including fish) and cause birth defects.

Some antifoul components, like TBT, are so toxic that they’ve been banned in Australia.

About the SeaPen

Which Vessels Can the SeaPen Support?

The SeaPen is suitable for almost all recreational and light commercial vessels 6–20 metres (19.6–65 feet) long with outboards, stern drives, jet drives, and V-drives. That includes monohulls, catamarans, tri-hulls, pontoon boats, wake and ski boats, and trailer-sailors.

SeaPen FAQs

Can I walk on my SeaPen?

Yes, you can walk on your SeaPen. The SeaPen’s high-density polyethylene frame can support your full body weight, giving you access to all sides of your vessel.

 For more stable footing, add an anti-slip aluminium walkway  to your SeaPen’s frame.

Is the SeaPen really dry?

Yes, the SeaPen keeps your vessel’s hull dry to prevent marine growth. When you dock and close the SeaPen’s rear gate, any trapped water will be automatically detected by the bilge pump system, which will pump out the water and go into standby, detecting water every 2 hours.

The bilge pump system is separated from your vessel’s hull by a layer of our patented rope mat, which provides ventilation by creating an air gap around your hull and running gear. The SeaPen’s frame – which sits approximately 200mm above the water – prevents any additional water entering once the rear gate is shut.

What happens if it rains or a wave washes into the SeaPen?

The SeaPen’s bilge pump system turns on every 2 hours to sense for water, pumps out any that is detected, and then goes back into standby. Heavy rain, wake, storm surges – your SeaPen will take care of them all.

How long does the SeaPen last?

The SeaPen doesn’t have a fixed lifespan. Both its frame and skin are built for durability, and, with regular servicing, it can support your vessel for upwards of a decade. Many of our customers’ SeaPens have been in service for over 15 years.

Any components that fail over time due to wear and tear can be individually replaced by one of our technicians. Keep in mind, though, that your SeaPen is just like your car or boat. It’s built for durability, but it still needs annual servicing to perform at its best (and preserve your warranty).

Make sure you book a maintenance service every 12 months.

Can I flush my motors in the SeaPen?

Yes, you can flush your vessel’s motors in your SeaPen. Attach flush muffs or part-fill your SeaPen with fresh water. Once your motor intakes are submerged, idle the motor in neutral. If you have an outboard, you can also attach the flush muffs.

What maintenance does the SeaPen require?

The SeaPen requires minimal maintenance. Each time you dock your boat, wash it down with fresh water through the Smart-Pump system – which you can do by washing down your vessel.

We also recommend booking a preventive service every 12 months. The SeaPen is designed for durability, however, any parts that need to be replaced due to wear and tear can be replaced.

Can my SeaPen be insured?

Yes, your SeaPen can be insured. Most insurers can include your SeaPen in your vessel’s insurance policy.

Where is the SeaPen manufactured?

We manufacture all SeaPens in our state of the art factory on the Gold Coast, Australia.

Does the SeaPen prevent osmosis?

The SeaPen is designed to prevent marine growth and reduce your ongoing maintenance and running costs. It doesn’t prevent osmosis (the bilstering process that occurs when water penetrates your hull material). While dry-docking can help slow osmotic blistering, the actual cause is exposing a non-moisture-proof material to water – which will happen whenever you take your vessel out on the water. There are barrier coats available that will waterproof the hull and provide a number of other benefits. This will give you peace of mind that you’re looking after your prized asset.

The SeaPen skin is a waterproof, growth resistant membrane> Once the gate of the SeaPen is closed, the bilge pump system switches on and drains all the water away until the SeaPen is empty. The SeaPen shrink wraps around the hull of the boat and the woven rope mat creates an air gap that allows ventilation and also helps to wick water away from the hull down to the bilge system, where it is drained out. The pump system turns on every 2 hours to sense for water and then goes back into standby.

How is the SeaPen anchored in place?

The SeaPen is usually roped off in a similar way to roping your boat off at your berth.

Dry-Docking Means Better Boating

The SeaPen is the easiest way to maintain your vessel’s health and performance.
