Mast Manufacturers

Web Link Selden
Now offering a sleeved 2420 section Mirror mast which is widely regarded as being more flexible than a Superspars M9. I understand the stiff lamda section mast is no longer available.
Web Link Superspars Superspars M9 section continues to be popular. More recently they are offering a Mirror mast using their MHA section (Holt "Aldebaran") which is more flexible than M9
Web Link Sailing School and Rigging Sell booms & spinnaker poles. Run by Craig Bond who has 30 years of experience with Mirrors at the very highest level.
Web Link Trident-UK Trident-UK manufacture a Bermuda mast which can be dismantled into 2 pieces so you can still stow it in the boat for trailing etc. Trident also still manufacture Gunter masts (alloy tube with wooden end plugs)
Web Link Collars If you want an traditional wooden Gunter mast (i.e. all wood, no alloy tube), Collars based in Oxford should be able to supply one.
Web Link Goldspar
Australian based, uses a 50mm tube for a bottom section with a spun conical top section. Sadly Goldspars stopped dinghy mast production in 2018.
Web Link Hawk Marine Products
Manufacturers of Needlespar masts. I understand (2019) that Hawk Marine Products have now stopped production.
Web Link Z-Spars
Made by Craig Bond when he worked for Z-Spars & popular with sailors from Brightlingsea. They were a round tube with a taper above the hounds, anodised black with a rivetted on track. They were pre-bent to the maximum allowed under the rules. Sadly no longer available.
