There are even boats sailing the ocean that have had hulls made from recycled drink bottles, and [http://en.wikipedia.org/wiki/Thor_Heyerdahl Thor Heyerdahl] famously sailed across the [[South Pacific]] in a raft made from balsa wood.

Do a lot of research, a lot of reading, and post a bunch of questions to forums before deciding on the hull of your boat.  It's probably the single most important decision you will make.

Types of Hull

You're probably going to find more argument on line about hulls of boats than almost every other topic -- with the possible exception of Multihull vs Monohull. The types of hull to choose from include:

  • Fibreglass (GRP) either solid GRP or composite (balsa or foam core)
  • Steel
  • Wood
  • Carbon Fibre
  • Aluminium
  • Ferro Cement

Contents

There are even boats sailing the ocean that have had hulls made from recycled drink bottles, and Thor Heyerdahl famously sailed across the South Pacific in a raft made from balsa wood.

Do a lot of research, a lot of reading, and post a bunch of questions to forums before deciding on the hull of your boat. It's probably the single most important decision you will make.

Advantages and Disadvantages of Hull Materials

Material Advantages Disadvantages
Steel Stronger than any other hull material Tendency to rust, both inside and outside of the hull.

Heavy


Solid Fibreglass Stronger than composite fibreglass although not as strong as steel.

Resists corrosion.

Low maintenance.

Heavier than composite

Prone to osmosis.

Expensive to maintain and repair when repairs are required.

Fibreglass -- Balsa Core Stronger than Foam core.

Reasonably low maintenance.

Light weight, although not as light as foam core.

Heavier than foam core.

Prone to osmosis. Osmosis, when it weeps into the core, can destroy the hull.

Relatively weak compared to steel and solid fibreglass.

Fibreglass -- Foam Core Reasonably low maintenance.

Light weight.

Prone to osmosis.

Relatively weak compared to steel and solid fibreglass. Probably the weakest hull material, most prone to hull breaches especially if used below the waterline.

Expensive to maintain if maintenance is required.

Wood Lower weight than steel.

Can be cheap to maintain if maintenance is kept up regularly.

Does not rust.

Not prone to osmosis.

High maintenance.

Relatively weak compared to steel. Perhaps weaker than solid fibreglass depending on the thickness.

Build cost is relatively high. Most commonly found in older boats built before newer materials such as fibreglass became cheaper.

Ferro Cement Cheap to build and maintain.

Not prone to osmosis.

High maintenance.

Relatively weak compared to steel.

Can be prone to rust.

Heaviest build material, ferro cement boats often do not sail well.

Aluminium Low maintenance.

Not prone to rust (but destructive corrosion can still occur if left untended).

Not prone to osmosis.

Does not require painting or any other barrier coats.

Relatively weak compared to steel (but stronger than wood and most GRP).

Expensive to build and maintain.

Many antifouls are not compatible with aluminium.
