Summary Analysis of the Design Ratios for the Moody 425

1. A Sail Area/Displacement Ratio of 16.4 suggests that the Moody 425 will, in the right conditions, approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.

2. A Ballast/Displacement Ratio of 40.0 means that the Moody 425 will initially stand up reasonably well to her canvas in a moderate breeze, but she'll need a reef in the main to avoid heeling excessively in a gust.

3. A Displacement/Length Ratio of 236, tells us the Moody 425 is a moderate displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic effect on her performance. Most of today's sailboats intended for offshore cruising fall into this displacement category.

4. Ted Brewer's Comfort Ratio of 28.6 suggests that crew comfort of a Moody 425 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not encouraging news for anyone prone to seasickness. 

5. The Capsize Screening Formula (CSF) of 1.9 tells us that a Moody 425 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.

One of the main attractions of the Moody 425 is its generous accommodation layout that can sleep up to eight people. The boat has three separate cabins, two heads, a large saloon, a navigation station and a galley. The interior is finished in teak woodwork and blue upholstery, creating a warm and cozy atmosphere.

The master cabin is located in the stern of the boat, and has a centerline double berth, two hanging lockers, two drawers, and several shelves. It also has an en-suite head with a shower, a sink, and a marine toilet. The master cabin can be accessed from the cockpit or from the saloon.

The forward cabin has a V-shaped double berth, a hanging locker, two drawers, and several shelves. It also has an access door to the forward head, which is shared with the saloon. The forward head has a shower, a sink, and a marine toilet.

The third cabin is located on the starboard side of the boat, next to the navigation station. It has two single bunk beds, a hanging locker, and some storage space. It is ideal for children or guests.

The saloon is spacious and bright, with four large windows and four opening hatches. It has a U-shaped settee on the starboard side that can seat six people around a folding table. The table can also be lowered to create an extra double berth. On the starboard side, there is another settee that can be used as a single berth.

The navigation station is located on the starboard side of the saloon, and has a large chart table with storage space underneath and an instrument panel.

The galley is located on the port side of the saloon. It has an L-shaped counter with plenty of work space and storage space. It also has a double stainless steel sink, a three-burner gas stove with oven, a top-loading refrigerator, and a front-loading freezer.

Hull and Deck
The Moody 425 has a solid fiberglass hull that is reinforced with stringers and bulkheads. The hull shape is round-bilged with moderate overhangs at both ends.

The deck is also made of fiberglass with balsa core for stiffness and insulation. The deck is molded in one piece with an integral toe rail and raised bulwarks for safety, and is wide and flat, with plenty of handrails and cleats. The anchor locker is located at the bow, with an electric windlass and a bow roller. The boat also has a sugar scoop transom that makes boarding and swimming easier.

The Moody 425 has a spacious cockpit that can accommodate six people comfortably. The cockpit also has a large locker, a folding table, and an access hatch to the aft cabin.
