Introduction

Introduction •• ••

Passion / Hobby Interesting topic for major project

Opportunity •• ••

Current watercrafts do not directly cater for spearfishing Growing trend in numbers spearfishing

Aim Research and evaluate spearfishing in New Zealand and watercraft products within this market. The design must be well priced for the market whilst being extremely functional to make the process of spearfishing easier and more enjoyable.

Research Methodology

•• Surveys

Blackdog Cat Boat Test

•• Spatial Ergonomics

Hen & Chicken Islands

•• Discussions with Experts •• Interviews

T-Point

•• Observational Dives •• Boat Testing Mana Makara

Observational dives and boat testing were the most beniftial research methods.

Performance / Experience Issues

•• Difficult entry / exit to watercraft due to poor platforms and high sides. •• Lack of equipment storage creates a tangled mess. •• Fish bins / gear bags become obtrusive.

Benefit

•• Difficult entry / exit from watercraft.

•• Low boarding platform

•• Smooth easy transition between craft and water.

•• Equipment is usually put on the floor and float lines tangle.

•• A system for storing floats and their lines.

•• So they do not tangle into a mess.

•• Fins and spearguns are long and are awkward objects to store.

•• A method for storing fins and guns without being in the way.

•• Allowing the user room to move around the craft.

•• Fish bins are usually at the back in the way of entry and exit points.

•• A dedicated underfloor catch tank.

•• Allowing the user room to move around the craft.

•• Craft needs to be very stable.

•• Catamaran hull

•• Provides optimum stability

Spearfishing Watercraft

Concept Development

• • Understanding spatial ergonomics and dimensions. • • Sketching forms for an aesthetic. • • Role play the experience to generate ideas.

Evaluation of Design

Nick Hobson

Darren Shields

Spearfisherman + Industrial Designer

World Champ Rep / Store Owner

•• "The Waterline Marine Spearfishing craft seamlessly integrates the storage and organization of spearfishing gear with the process of getting in and out of the water, thus maximizing fishing time. The low platform at the rear, assists with re-entry to the boat after a dive, usually a tricky balancing act with 7kg’s of weight strapped to you. This is a feature all to often overlooked for a craft of this size and calibre."

••

"More hand holds are necassary"

••

"Console could be brought back"

•• "As someone who hopes to be in the market for a dedicated spearfishing boat, the Waterline Marine appears to offer genuine improvements to the spearfishing experience."

•• "Room for divers, boarding platforms and antislip flooring are great." •• "Well constructed for durability and attention to recylability at a later date."
