Bombers supply a number of Weymouth bits to take account of the Dressage legal needs of their clients.
Equitain supply the two main versions, in a selection of sizes with 55 or 75mm shanks.
In brief, the major difference in the angle of the mouth piece. One is forward and one is not.
The Fielder Weymouth is a curb bit designed to be used in conjunction with a Bridoon in the Double Bridle. The Weymouth introduces pressure in many places. In the mouth, there is tongue and bar pressure. The curb chain introduces curb pressure, and the shanks also add poll pressure.
The upper cheeks on the Fielder Weymouth are bent slightly outwards to allow room for the horse’s cheeks. It also has an oval top ring so the bridle’s cheekpiece doesn’t interfere with the curb chain. The lower cheeks are 55 mm long.
In the PF Forward Port, the port allows for tongue relief and is angled slightly forwards. This angle discourages the horse from pushing its nose out too far in front of the vertical.
The second major version of the Weymouth is the Happy Tongue Straight.
The Happy Tongue Straight is a solid mouth bit which is ported to relieve tongue pressure but is not curved. This makes it slightly harsher than the curved Happy Tongue.
The Happy Tongue Straight complies with FEI requirements.
