Tell us about the sailor and the boat they use now. Dinghy Base checks each component independently, then shows whether to keep it or what to consider instead.
1. The sailor
2. The boat
Mast, boom and sprit stay separate because mixed stiffness combinations are normal.
KIT CHECK
For a 40 kg, age 11 club racer
Sail
CURRENT
North Sails C6
GREEN · Good fit
Comfortably within the published 36–44 kg range.
RECOMMENDATIONNot at this stage.
Mast
CURRENT
Optimax MK3 Medium
AMBER · Approaching upper limit
Still within the published range, but 40 kg is in its upper third (30–40 kg).
RECOMMENDATIONNot at this stage.
Boom
CURRENT
Optimax 40 mm
INFO · Review as part of the spar combination
Boom stiffness is deliberately assessed separately from the mast. A sailor can legitimately combine a stiffer boom with a softer mast or sprit.
Hyperflex is not treated as a light-sailor-only component. Optimax offers Hyperflex across MK3 Flex, MK3 Medium, MK3 and MK4 combinations.
RECOMMENDATIONNo automatic change — Hyperflex can remain appropriate with stiffer mast/boom combinations.
Foils
CURRENT
N1 XR-Light
GREEN · Published weight fit
XR-Light is published for sailors under 45 kg.
RECOMMENDATIONNot at this stage.
How Dinghy Base judges this
Weight ranges come from the same published sail guidance used in Sail Selector. When the current sail moves outside its range, the review now returns every verified sail in the catalogue that includes the selected sailor weight. Mast, boom and sprit remain separate rather than being treated as one fixed spar set.
