Commercial Boat Engineering

SFM Marine has an expert team on site to design and install mechanical components, marine electronics and metalwork adjustments for commercial boats.

Need project management for your fleet maintenance?

Require engineering, mechanical, metalwork or marine electronics? 

Want to increase boat performance and efficiency? 

Intelligent engineering with superior craftsmanship.

Whether you own a 14-foot trailer boat, party-boat, workboat or professional fishing boat, you can rely on SFM Marine’s services for all of your engineering works.

With more than a decade in the industry, we realise that the key to fast turnarounds and quality work is in project management, which is overseen by dedicated professionals.

Marine protection including the latest range of anodes.

A vessel that’s appropriately set up with galvanic protection will require less underwater cleaning and long-term maintenance costs.

We can supply and fit electrolysis blockers to eliminate stray currents when connected to shore power, now mandatory in many marina bylaws.

Ask for comprehensive testing of your vessel’s galvanic and electrolytic protection setup, including the vessel’s internal bonding condition.

You can rely on SFM Marine.
