Can I flush my motors in the SeaPen?

Keeping your motor performing in top condition is vital and in order to do this, it’s best to flush your motor after each use. This process is easy in a SeaPen; you can either attach flushing muffs or better still, you can part-fill the SeaPen with fresh water until it’s above the motor intakes and then simply idle the motor in neutral.

Why shouldn't I antifoul my boat?

Antifouling is a product intended to inhibit marine growth and is formulated with toxic copper, organotin compounds, or other biocides. Antifouling doesn’t stop marine growth from occurring in the long-term and decreases your boat performance when applied.

Furthermore, it has to be removed and re-applied on a regular basis. All this leads to a significant outlay of time and money with few benefits that improve your boating lifestyle

SeaPen is the market-leading alternative. By dry-docking your boat at water level in a SeaPen, you eliminate the risk of marine growth occurring on your boat. This allows you to keep a gel-coated boat at water level, without fear of it being damaged by marine life.

SeaPen’s advanced dry-docking technology means every time you take your boat out, it will perform like new with a growth-free hull for maximum efficiency. Not antifouling your boat will also help maintain the boat’s market resale value

Never Antifoul Again. Ever.

What does the green rope mesh do?

SeaPen’s patented rope mesh is crucial to the dry-docking process and serves 3 primary functions.

1. It creates an air gap between the hull of the boat and the skin of the SeaPen – the crucial ventilation stage in the dry-docking process.

2. It protects the SeaPen skin from the sharp points of the boat; propellers, trim-tabs etc.

3. It gives the SeaPen structural strength, with a breaking strain of 76,000 kg per square metre.

What maintenance is required?

There is very little maintenance involved with the SeaPen. The key points are:

1. Rinse fresh water through the SeaPen. Every time you rinse down your boat, it will rinse fresh water through the SeaPen

2. There is a sacrificial anode attached to the SeaPen bilge system that needs checking and periodically replacing.

3. We recommend annual preventive services to extend the life of the SeaPen.
