Mast Sections

Enquire
About

C-Tech mast sections are manufactured using a mandrel wrapped production system and the highest quality pre-preg materials. Custom designed laminates are made up of a blend of standard and high modulus carbon fibre to achieve bend characteristics. Mast sections are autoclave cured for an aerospace quality laminate consolidation. C-Tech has a range of mandrel sections to choose from to optimise weight and stiffness for any yacht from dinghies, foiling classes, small keelboats or multihulls. We are also able to custom-build mandrels in-house for special projects.

Keelboat Spreaders

Enquire
About

Keelboat spreaders require more articulation at the inboard end (IBE) then dinghy spreaders, so many keelboat spreaders between about 35ft to 70ft will be attached using spreader bars. These can be built from printed titanium, alloy or carbon.

About

Fixed Spreaders

Enquire
About

Fixed spreaders can be supplied mounted directly onto the mast for local deliveries. For overseas deliveries spreaders are mounted on a band, which can fit externally to the mast or fits on the sleeve between the two mast sections.

Adjustable Dinghy Spreaders

Enquire
About

In some classes being able to adjust spreader angles and lengths has led to the development of the C-Tech Carbon Adjustable Spreaders. On the IBE the front of the spreader is attached to a pin and the aft end there is an adjustable threaded eye, by removing the aft pin and either screwing in or out the spreader angle will adjust up to 15 to 20 degrees in either direction (from the neutral position). At the OBE of the spreader we use a standard Selden (or Proctor) OBE which allows two wire positions to be selected as well the length of the spreader can be altered plus or minus 25mm from the neutral position.

About

Lowers/D1 Attachments

Enquire
About

Many yachts require a set of lower stays near the gooseneck to control or restrict lower mast bend. On yachts that use T-plates we will often fit an internal sleeve or reinforce the outside of the mast to compensate for the hole placed in the mast at a high load location. On the 16ft and 18ft Skiffs and classes like the Merlin Rocket and Shaw 7m we fit a custom made D1 (lowers) carbon fitting as this is glued to the mast and requires no holes in the mast, being on the front of the mast also gives clearance to the lowers stays.
