About Penfold Marine

Penfold Marine was a family owned business run by two generations of the Penfold family situated on the waterfront at Nelson Place Williamstown. The business commenced in 1965 and traded as Williamstown Slipways until 2004 when the site was redeveloped and a forty tonne travel lift was installed at the wharf. During our 55 years on the waterfront we have built up a full service, repairs and maintenance marine business. We service and maintain commercial and privately owned vessels.

We employ qualified marine mechanics and shipwright/boat builders to carry out all repairs and servicing required. Penfold Marine has an excellent reputation within the marine industry.

We are a full marine service provider located on Savages Wharf with direct access to all lifting and hardstand services. As a multi skilled and responsible company we hold all insurances required to carry out business within our industry.

The team at Penfold Marine are trained in servicing and repairing Mercury Mercruiser engines. We look forward to helping you stay on the water with all your servicing, repairs and maintenance needs.
