Interior Layout and Accommodations
The interior of Katrinka is designed to be a comfortable and highly usable space both for offshore passages or for quiet times at anchor in a secluded cove.
Special attention has been made to assure the spaces down below are light and airy with a white painted color scheme (trimmed in Teak) reflecting natural light from hull ports, overhead hatches and numerous deck prisms along with ventilation provided by opening hatches, well-placed dorades and fans in every cabin. Well-ventilated for keeping cool,  Katrinka is also equipped with diesel-fired hot air heating allowing her owners comfortable cruises to higher latitudes extended use into the shoulders of the New England sailing season.
Safety and comfort is also a special consideration to the below decks areas as the current (and hopefully future) owner has kept up Katrinka’s reputation as a competitive ocean racing and long range cruising boat. To this end the interior design maximizes comfort for long term use (a rested sailor is a good sailor) and safety with features like ease of access to critical equipment, thru-hulls, etc. and positive locking mechanisms making sure that locker doors, drawers and cabin soles stay in place in the roughest of weather,

Passageway Aft
Immediately aft of the forward cabin is a passageway aft to the main saloon.
Cabin sole in passageway is varnished Teak and Holly
To port of the passageway is the forward head and opposite (to starboard) is a hanging locker with the door to this locker doing double-duty as a privacy door for the forward cabin.
The forward head area features Raritan manually operated marine toilet, storage areas above / outboard and below stainless steel counter tops with Teak fiddles, Teal trimmed mirror, stainless steel sink basin, handheld faucet / shower head,  Teak and Holly cabin sole and Teak shower grate.

Varnished Teak drop-leaf table with drawer storage on center-line of main saloon. Table is flanked by straight settee to starboard and L-shaped settee to port with pilot berths above and outboard of the settees both port and starboard and bin storage space outboard of the pilot berths. Additional storage space in deep drawers and locker under and forward of the pilot berths. Port and starboard under the pilot berths (aft end) are stainless steel Vitrifrigo drawer-style refrigerators.
Overhead hatch, fixed hull ports and deck prisms provide an amazing amount of natural light with reading and dome lights for after the sun goes down. Natural and artificial  ventilation of the main saloon is more than adequately provided by dorade vents, opening hatch (with screen) and well-placed fans.
Main Companionway
Main Companionway is located starboard aft in the Main saloon. Exit / Entrance to the below decks area is by way of a companionway ladder with varnished teak rails and bare teak steps. The companionway ladder lands on the sound-insulated engine box with one more step down to the main saloon cabin sole.
Outboard of the companionway is a wet locker, courtesy lights at base of ladder and EPIRB mounted within reach of the upper companionway opening.
Galley Area
Galley is located aft of the main saloon and to port. This area is extremely well lighted with 3 deck prisms, 3 overhead dome lights, a fixed hull port light and an opening hatch directly above. Generous storage for dry goods, china, glasses, etc. in lockers, drawers and glass racks above and below the counter tops. Counter tops are of stainless steel with high teak fiddles to keep everything in it’s place. Cooking is done with a gimbaled Force Ten 3-burner stove and oven. Cold food storage is under-counter with large well-insulated, stainless steel ice box kept cool with Seafrost refrigeration. Single stainless steel sink basin supplied with hot and cold pressure water and manually provided (foot-pump) salt water.
Aft Head Area
The aft head compartment is located opposite of the galley and aft of the main companionway. Like all the interior spaces the aft head is very well lighted with 2 deck prisms overhead, a fixed hull port light and electrical lighting. Joinery fronts are white painted with varnished teak trim, counter tops are stainless steel and underfoot the cabin soles is Teak and Holly with a teak shower grate. Hot and cold pressure water provided by way of hand-held faucet / shower head and Raritan manually operated marine toilet.
Generous storage in lockers above and outboard of the toilet along with additional lockers and drawers under counter. Handy access to ft end of the engine compartment by way of sound-insulated doors under counter.
Passageway to Aft cabin
There are hanging lockers located to port and starboard of the passageway to the aft sleeping cabin. Very handy for storage of foul-weather gear these also house electrical and plumbing equipment and make for easy access to key components for maintenance purposes.
Aft Sleeping Cabin
As often mentioned in this description Katrinka’s interior spaces the aft sleeping cabin is quite well lighted by way of fixed hull portlights both port and starboard, opening port on center line (facing forward), an overhead opening hatch along with well-placed electrical lighting. The aft cabin is also well ventilated with the above mentioned opening port and hatch along with well-placed electrical fans and for cooler nights the aft cabin is heated as a zone of the diesel hot air heating system.
There is a true double berth (Pullman-style) to starboard with storage drawers under berth, storage lockers located forward and outboard and the fixed hull port right at eye level for early morning wake-up light. Opposite (to port) is a forward-facing navigation station / office space with full size chart desk with drawers storage under, navigational electronics displays forward, bookshelf for reference materials and an under counter locker dedicated to storage of ship’s information and equipment manuals. Seating at the nav station is provided as a part of an L-shaped settee that wraps around the aft end of the cabin providing a perfect spot for quiet reading or donning a new dry pair of socks.
