Jeremy Newman has two new fibreglass daggerboards for sale for £100 ONO each. Note however that they will not fit the case on a Winder! (for the record Winder daggerboard cases are narrower than 14mm so "standard" 14mm thick Milanes, Duffin, Trident and other boards won't fit). They were manufactured by White Formula UK Ltd.
www.whiteformula.com/WhiteFormula_UK/Home.html
and are identical to boards supplied by Trident-UK. They will need top handles fitting & Jeremy will post them.
