If you’ve been curious about the SeaPen — how it works, whether it suits your boat, or how it stacks up against antifouling — you’re in the right place. We’ve pulled together the questions we hear most often and answered them honestly. No jargon, no hard sell.
How does the SeaPen work?
A SeaPen is a floating dry dock solution that keeps your boat dry while floating at water level. It creates an isolated enclosure around your vessel, with a built-in bilge pump that automatically checks for water every two hours and pumps it out if detected. A non-wicking rope mat inside the enclosure creates an air gap between the hull and the SeaPen’s inner skin, allowing for ventilation and keeping the hull dry between uses.
The result is a boat that stays dry at its mooring — without the need for a boatyard haul-out.
Is the SeaPen suitable for my boat?
The SeaPen is designed for boats approximately 6–20 metres in length and accommodates a wide range of hull types and drive configurations — including monohulls, catamarans, tri-hulls, pontoon boats, wake and ski boats, and trailer-boats. Compatible drive types include outboards, stern drives, jet drives, and V-drives.
If you’re unsure whether your vessel is a good fit, get in touch with the DockPro team and we’ll help you work it out.
How is a SeaPen installed?
SeaPen installation is carried out by DockPro’s professional service technicians. The system is roped off to your existing structure, and our team handles the full installation process from start to finish. We have technicians located across South East Queensland, Sunshine Coast, Northern NSW, Sydney, Melbourne, Mandurah, and Auckland — so wherever you’re based, we’ve got you covered.
Is a SeaPen worth it compared to antifouling?
For most boat owners, absolutely. Antifouling can cost several thousand dollars each time — and needs to be redone approximately every 12–18 months. With a SeaPen, your hull stays dry between uses, so you can skip the antifoul altogether.
A clean hull also means better performance and less drag on the water. Most owners recoup their investment within approximately five years or less, and the day-to-day convenience is hard to put a price on — your boat is ready to go when you are, without the ongoing trips to the boatyard. And unlike antifouling, at the end of its life you still have a physical asset on your hands.
Does a SeaPen require much maintenance?
We recommend an annual service to keep your SeaPen in top condition. All parts are replaceable, so if something needs attention you won’t have to replace the entire unit. Like any marine product, how much maintenance is involved depends on how well it’s looked after — but a well-maintained SeaPen is built to last. There are still well-maintained SeaPens in Australia that are over 15 years old.
Do marinas and boat clubs use SeaPens?
Yes. The SeaPen is an increasingly popular solution for marina operators looking to offer premium dry-docking without the infrastructure of a full boatyard. It provides an on-water dry storage solution for vessels 6–20 metres and is trusted by marinas and boat clubs across Australia, New Zealand, and internationally.
Whether you’re a marina manager looking to maximise your facility, or a boat owner exploring your options, the SeaPen is worth a closer look.
