F4

Foil brand with little UK retail presence but a big reputation among the foiling-obsessed — “the talk of the town” for the hosts, with several back-to-back hyped releases (an Orca, a GP, and a downwind race foil with a “Warhammer”-style name Liam couldn’t recall).

• Ep 147: F4 foils won the season’s first Hawaiian downwind race under Edo Tanas (Kai second), who rode them rather than his sponsor Slingshot’s (Slingshot hadn’t developed a downwind foil in time). F4 dominated the field the way Axis had the previous year. Liam wants to try one on a US trip; a listener quip likened it to “an Eagle X.” (Brand details drawn from the auto-transcript; model names uncertain/garbled.)
• Ep 144: named in passing among brands that might, or already do, build a Tuttle mast.

Ripple additions (batch 2, 2026-07-20)

• Ep 88 (Daniela Moroz): an early race foil she rode before moving to Mikes Lab.
• Ep 142 (Dave Kalama): switched from a lifetime on Go Foil to F4 (Orca, mainly 685) for downwind, citing ease and low-end.
