Construction:
The J/121 is constructed using advanced, performance-oriented techniques typical of modern racing yachts:

Hull & Deck Material:
Made from fiberglass (GRP) with a balsa or foam core for stiffness and reduced weight.
Vinylester resin is used to enhance strength and minimize water absorption.

Hull Design:
The hull is a light, semi-displacement shape with a plumb bow and wide aft sections for speed and stability, designed by Alan Johnstone.
Reinforced areas around the keel, chainplates, and rig to handle high loads.

Deck & Cockpit:
Decks are cored composite for stiffness and weight savings.
Non-skid surfaces are molded into the deck for safety.
Ergonomic cockpit with lines led aft for short-handed handling.

Keel & Ballast:
Fin keel made of steel + lead for a low center of gravity.
She incorporate twin water ballast tanks to increase stability without extra crew weight.

Rudder & Steering:
Balanced spade rudder, with twin wheels for precise handling.

Interior:
A cleverly laid out interior design is both racing practical, but also offers the typical J/Boat comfort levels, that makes these boats a much nicer environment below decks.
The saloon is packed with sleeping berths, whereby the back rests smartly form the upper bunks when required.
A full double cabin aft to Port and heads to Stb, with additional aft cabin for storage. A smaller sleeping area is possible, but will require another bunk to be installed.
The forepeak is kept light and clear for sail handling and wet weather gear storage.
Centrally there is an L shaped galley area to Port and navigation station to starboard.
Lightweight, functional interiors with laminated bulkheads, designed to minimize weight while providing basic accommodations.
Particular thought has gone into the offshore configuration.
