The genuine Optiparts 48-litre high-float airbag, made by one of the best-known names in Optimist equipment. Its standout feature is the fill stem: the twist-lock valve sits on the end of a stem rather than on the bag itself, so the bag can be topped up on the water without the sailor leaning in with their head near the bag.

Why the fill stem matters

• Safer inflation for young sailors – their eyes stay above the gunwale while they top up, so they keep watching the course and other boats
• Easier to reach – no need to wriggle under the thwart to find the valve
• No accidental deflation – the stem tucks neatly under the airbag straps when not in use

Details

• Brand: Optiparts
• Volume: 48 litres high float, within the Optimist class requirement of 45 ± 5 litres per buoyancy unit

Good to know

• An Optimist carries three buoyancy bags (one each side and one at the stern), so order three to fit out a full boat.
• Inflate until firm but still slightly soft; an over-inflated bag can burst as it warms up in the sun.
