Introduction
Aluminum boats, prized by fishing boats enthusiasts and aluminum boat builders, are known for their durability and lightweight design, thanks to the material for aluminum boats like high-grade aluminum alloys. However, even the toughest aluminum hull can suffer from galvanic corrosion, acidic corrosion, or physical damage like dents and corroded holes, necessitating aluminum boat hull repair. Whether you’re an aluminum boat builder addressing corrosion sites or a boat owner fixing a boat in question from mixed questions on forums like ifish.net, understanding the costs and techniques involved in aluminum boat hull repair is crucial. This guide covers everything from DIY fixes using a wire brush to professional TIG welding, ensuring your vessel—whether stored or fresh off the water—remains seaworthy.
Understanding Aluminum Boat Hull Repair
Why Aluminum Hulls Need Repair
Aluminum hulls face corrosion damage from galvanic corrosion, caused by salts of aluminum reacting with stainless steel fasteners or bilge solution near the fuel tank. Corrosion in progress can lead to corrosion site pits, radius corrosion failures, and even tank bottom radius corrosion, all requiring aluminum boat hull repair. Physical impacts create actual holes or bored corrosion, compromising the parent metal and clean metal surfaces, making repair essential.
Common Damage Types
Dents
Dents from collisions with a concrete dock or damn dock are common. Aluminum boat hull repair for dents costs $100-$300, using tools like a wire brush and soda blast for surface preparation.
Cracks
Cracks, often from metal strain or corrosion byproducts, need functional welding or sealant glue. Costs range from $200-$1,000+ based on size weld and complexity.
Holes
Corrosion pockets or the largest hole from impacts demand epoxy coatings or clean weld techniques, averaging $500-$2,000+ for aluminum boat hull repair.
