Why Kite + AI currently calculates for twin-tip only

Twin-tip is the baseline learning and recreational scenario

A typical beginner progression teaches independent riding, waterstarts, holding a course and returning towards the launch on a twin-tip. For the portal's main audience of learners and adult recreational riders, it is the most recognisable board and supports a clear question: is there enough wind for me and my kite to ride normally?

The international IKO pathway separates the core Kiteboarder progression, from Discovery through Advanced, from later Evolution disciplines. Hydrofoil is a separate Level 5 discipline, and its official course includes equipment choice, a dedicated site assessment, board handling, entering and leaving the water, body dragging and a separate start progression. It is not merely another board in the same calculator.

What an experienced rider can take from the twin-tip result

When the service finds a suitable twin-tip window, an experienced hydrofoil or directional rider still gains a useful starting point: where wind is expected, how closely the models agree, the direction and gusts, and which sensor or camera to check. That can be enough to decide where to continue a discipline-specific assessment.

The rider makes that translation. A hydrofoil can ride in lighter wind and may require a different kite size; a directional depends more heavily on waves, current and shore break. The portal therefore does not currently issue an automatic kite size or dedicated score for either discipline.

Suitable for twin-tip does not automatically mean safe for a foil

We will not claim that a twin-tip window is automatically safe for hydrofoiling. Even the twin-tip result is preliminary guidance rather than launch clearance. A foil adds critical questions about depth, reef, rocks, sandbanks, debris and other underwater obstacles, space around other water users, mast length, falling technique and rescue options.

Official foiling materials explicitly connect mast choice to spot depth and conditions. IKO gives hydrofoil its own SEA assessment and learning progression. A foil has a mast, fuselage and wings; contact with them or the bottom introduces hazards that a conventional twin-tip does not. One green result cannot be transferred mechanically between disciplines.

• twin-tip: the service checks wind, gusts, spot-compatible direction, forecast horizon, weight, level and selected kite;
• hydrofoil: depth, underwater obstacles, mast and wing setup, a separate wind range and rescue plan must also be assessed;
• directional / wave: waves, period, current, shore break, reefs and exit technique also matter;
• for every discipline, the final decision is made at the shore rather than from one on-screen index.

Why we are not adding three attractive buttons today

Adding a button is easy; building a defensible calculation is not. Merely lowering the wind threshold for a hydrofoil would ignore depth, obstacles, the actual foil configuration and rider skill. It would look intelligent while creating false confidence.

Twin-tip therefore remains the single baseline mode. Experienced riders can use the forecast and spot ranking as weather guidance and apply their own discipline-specific checks. Hydrofoil and directional modes should appear only as separate profiles with their own inputs, limits and testable logic—not as renamed buttons.
