Flex is the enemy of response — both in surfing and pumping — so we've made the mast a touch thicker at the fuse connection, increasing stiffness. It may be a surprise to hear it's a touch thicker than the Katana, and in theory slower, but in practice the added stiffness is allowing us to fly higher on the mast, longer — reducing the wetted area and gaining efficiency.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThis results in a more efficient pump through a reduction in drag. When you're riding a larger wing, or you're a heavier rider, the benefit of reducing mast flex is immediately felt in overall control of the foil. The leading edge of the mast is vertical, and the bottom 40% does not taper, so you have an incredibly reliable foil section in the water during turns — creating consistent, confident movement. We've found we can push harder through our turns with increased flow.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe mast is 800mm, which is my favorite length for prone, tow, and downwind. The baseplate has been redesigned completely compared to the Katana. The bolts are set closer, which allows for more forward placement in the tracks — 1.2 inches in mast position is gained. The baseplate is also tapered at the mast connection, further reducing initial drag on takeoffs and touchdowns.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSince riding the Progression 800 mast, it's all I want to ride now.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e— Erik Antonson\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCover included — every UniFoil mast ships with a protective cover.
