Haslar Marina

As part of this two-phase project,  we designed and manufactured a bespoke floating concrete breakwater to reduce the wave climate at the eastern end of the marina close to the entrance of Portsmouth Harbour.

The first phase comprised the installation of two 60-ton 20m x 4m floating concrete breakwater units, carefully orientated to fit within the major reshaping of the marina which also involved realigning the iconic green lightship, a prominent feature in this busy corner of the marina.

The second stage added two 53 tonne 15m x 4m concrete breakwater units, extending the frontage of the marina from the bow of the lightship. The protection provided by this new fully serviced floating breakwater has enabled Haslar Marina to create 36 new berths, maximising usable space and increasing return on investment.

“Over the last couple of years, as boating has boomed, demand for quality berthing across the UK has increased,” says Jon Challis, Sales Manager at ICMS. “With space tight in many marinas, they’re looking at using sites not previously used due to exposed conditions. This is where our floating concrete breakwaters come in. They are designed specifically to reduce waves to a level where sheltered and comfortable berthing, either in a harbour or marina, can be provided – ensuring berth holders and visitors get a good night’s sleep.

“Combining high strength and flexibility, our concrete breakwaters are built to withstand severe weather and wave action. Being fit for purpose does make the units heavy, which means they can be challenging to transport and manoeuvre, but working closely with the team at boatfolk, and experienced local marine contractor, Baker Trayte, the installation has been seamless. Haslar Marina now has the first phase of the protection it needs to expand its berthing facilities.”

Ben Lippiett, Marina General Manager at Haslar Marina, comments: “We’re delighted with the work that Inland and Coastal has done, completing the final piece of our overall marina extension work. One of the unique selling points of our marina is its position close to Portsmouth Harbour entrance, but this has meant that there has always been a bit of motion at this exposed end of the marina, which has previously made it difficult to fill the berths.

“What our new floating concrete breakwater has done is to create a wave screen affect and has given us greater protection from the action of the wind and waves. The new breakwater has also give us is very usable, high load capacity space to accommodate much larger boats, superyachts and sail training vessels. Between the increase in berthing and the wave protection, it’s just finished off our berthing plan tremendously, we’re very happy.”
