FAQs

Why choose an air deck instead of an ally deck?

An air deck is a good option when you want a quicker, easier setup – particularly for solo sessions. If you often fish with others, you may prefer an ally deck option.

Why are air decks more expensive than I expected?

Air decks use a complex internal structure with many fibres designed to help the deck hold its shape and rigidity when inflated.

Do I need to modify my Hydrus to fit this air deck?

No modifications are needed for Hydrus IV to VII. Hydrus II and III require repositioning the transom floor support rails.

What PSI should I inflate to?

• Tubes and Air Keel – 3.6psi
• Air Deck – 8-9psi

Which size should I choose?

Choose 3.3m for the 330 deck size (221cm x 70cm), or 3.7m for the 370 deck size (250cm x 80cm).
