Marblehead – Astrix

Designed by John Taylor

LOA 1275mm   Beam 150mm   Approximate Displacement 5 kgs

The ASTRIX’s introduction in 2014 to our series of designs was a step up in ambition, to compete at the very top level of the Marblehead Class fleet. The proto-type hull featured in the World Championships in Gouda, (Netherlands) in 2014 and achieved a creditable result.

The main feature of the ASTRIX is the hard chines that run from the transom and along the hull line to the bow. The chine allows the waterline to extend quickly once the yacht heels. The hull form is ‘V’ shaped which allows the hull to grip the water and gives ASTRIX excellent pointing ability when sailing to windward.

During 2019, the ASTRIX has undergone a substantial upgrade program in terms of the yachts construction; this also included incorporating a new low profile rig configuration. During this years class championships a significant improvement in the designs performance was observed, as both competing yachts featured in A – Fleet on numerous occasions. Further development will continue towards the end of 2019, which will increase ASTRIX’s competitive life against the latest designs. 

Radio Pot Assembly

The winch and batteries are all encompassed within the radio pot. This ensures most of the weight is concentrated in one area. This system is used in most of our yachts.

Rig Specifications

Two separate mast sockets are built into the hull giving the skipper the choice, to use a combination of Swing and Conventional Rigs. It is recommended for skippers to choose high modulus carbon tube when constructing their rigs. There are various specialists who supply carbon tube and components for the rigs required for ASTRIX. It becomes a personal choice of how many rigs you wish to use, but generally 3 rigs will provide a skipper with a starting point. If the skipper wishes to employ 5 rigs, then the most suitable configuration is as follows.

A – (2150mm Luff Length) Swing Rig.
B – (1850mm Luff Length) Conventional Rig
C – (1600 Luff Length) Conventional Rig
C2 – (1400 Luff Length) Conventional Rig
C3 – (1200 Luff Length) Conventional Rig

Whichever supplier of rigs you choose, the thing to remember is the quality of stiffness for each carbon mast, and this is of paramount importance. If you’re choosing to build your own rigs using a kit, ensure you follow the instructions carefully from the rig supplier.

Astrix Hull Kits FROM £1100

The hull kit will come in the form of a part completed yacht, ready for the installation of the rig and radio equipment. The hulls are constructed using Carbon / Kevlar as an inner layer with carbon on the outer. Moulding is done using the vacuum bag technique. This type of construction method forms a light but robust hull. The hull, deck, rudder, fin box and other internal parts, including the bumper are all fitted to the hull. Deck fittings are installed, the standard length keel, ballast and rudder are also painted and included. A full sheeting line fed through the pulleys is installed with plenty of cord for you to attach to the booms. Your winch and rudder servo can be installed if you supply them. A full or standard length fins can be ordered to suit your sailing venue.
