       Blue Orca is a proposal prepared for a charter company interested in a boat for whale watching in the Queen Charlotte Islands. She is a 70 foot motorsailer of somewhat unique styling so that she would stand out and be easily identified by the average consumer. The large viewing ports in the main lounge will allow unobstructed observation in all types of weather while remaining warm and comfortable.

       I have put a crew cabin in the bow for a husband and wife team (captain and cook/hostess). They have a small desk for ship's papers and their own w.c. with shower. I have put another crew cabin amidship off the engine room for a marine biologist or other type of specialist. Here I have also included a desk for planning course material, etc. The passenger cabins have upper and lower berths but in the aft four cabins I have given the option of having the lower berths pull out to form a double. Each cabin has plenty of storage for personal effects. All w.c.s have a toilet, sink, and shower. The galley is equipped with a large fridge/freezer with microwave above, stove with oven, and dishwasher built into the pantry, accessed from the galley side. The pantry has full height cabinets for food stowage. The main cabin lounge will seat 12 in comfort, with viewing areas outboard of the settees for people who want to stand at the windows and watch the world go by. There are hanging lockers at the doors to the side decks for coats and wet gear, and a bar forward which is open to the galley below for pass through serving. The helm has a navigation table which will take full size charts and all electrical panels will be immediately available to starboard. A hydraulically powered winch mounted just off centerline will handle all sheets through sheet stoppers. All sails are roller furling for ease of handling. The side decks are wide for easy access, there is a sun pad for laying on the fore deck, and a large aft deck for lounge chairs, etc. There is a stairway aft to the swim grid, with access to the lazarrette from the swim grid with storage room for lots of water toys.

       The hull has a six foot draft for some of the shallower waters of the northwest and is a must if you plan on using this boat in the Caribbean. I have used twin keels and twin rudders for good sail performance and a hull form which will allow 18 knots speed with 500 s.h.p. using a single diesel with variable pitch prop. This data has been verified through a model test program.

       Blue Orca represents a concept which can be modified in length, width, and layout to suit the owners requirements. The possible variations are endless. If you are intrigued by this type of vessel, give me your requirements and I will prepare a sketch to suit your needs.

Plans include 6 sheets of drawings and a typewritten book of specifications.
