For anyone that may be interested, I have just had a new daggerboard made for my 26M by a fibreglass fabricator in the Glasgow area using Mike Clarke's mould. The daggerboard seems well constructed and perfectly serviceable, see pictures below. The finish I expect is perhaps not as smooth as the factory produced item from BW Yachts but a fraction of the price at £300 plus VAT and shipping.
If anyone would like to have one made please let me know and I will deliver the mould back to the fabricator and forward his contact details to you in order that you can deal directly with them. If not, I will return the mould to John Pompei for storage along with the fabricator's details for future use. My daggerboard is now back in its trunk and I am preparing to launch this weekend.
I can be contacted on 07917 794518 or e: firstname.lastname@example.org
kind regards to all
