Brief Summary

Next spring the venerable Burger Boat Company in Manitowoc, WI will launch the 142’ tri-deck Sea Owl II. While we have not met the owner (and don’t even know who he is), we can tell a lot about him by looking at the yacht he has designed. Note that we say “the owner” -- not the naval architect, nor the captain, nor even the builder. This owner has a well-educated eye that appreciates traditional, conservative motoryacht design (the kind that Burger is famous for). He is also an owner that has spent many days at sea over the years and knows that Murphy must have been a yachtsman. The owner is also a dreamer, a man who plans to do a lot of long-distance cruising in the company of friends. And, he is a connoisseur of fine, practical boat building. We think that we all – no matter what size motoryacht we’re thinking about buying, from 40’ on up – can learn from studying the designs of Sea Owl II.

Captain's Report

Burger 142 Sea Owl II
Burger Boat Company’s 142’ Sea Owl II has a beam of 28’ and displaces approximately 650,000 lbs. (295,454 kgs.), yet she has incredibly low horsepower engines aboard. This yacht is being built by a connoisseur of large motoryachts.

When we get on a vessel like the Sea Owl II and walk her decks, we usually have the same thought –“Now, this is the real thing.” Her wide side decks, high bulwarks, large freeing ports and huge cleats all signal “any ocean, any time.” Yes, there are much larger yachts built these days, the latest superyacht is over 500’ long, but frankly 150’ is about as large as a boat can be and still feel somewhat like a yacht, and not a cruise ship.

The main deck.

Saloon and Dining...

Let us enter this boat from the aft deck, go through the sliding doors, and take a quick walk-through. We guarantee that when most people walk into this foyer that they will think, if not say out loud – “Wow.” The reason they will say that is not because it is a large yacht full of glittering gold stuff, but because the foyer is empty! To the left and the right are book cases and on the deck is a simple, round compass rose, something that will be a recurring theme throughout the boat. The saloon which has seating for 11 people, but that is not the important aspect of this deck. Rather, the focal point of this space is the dining area. A large, round dining table is set in a circle on the sole and it is accommodated with rounded bulkheads forward, creating a dramatic circular effect. The owner of this vessel is a sociable person who likes dinner party conversation to be light and gay with everyone participating – something that is best accomplished only with a round table. Our guess is that when this whole space was designed it started with width of the chairs and the circumference of the table. Note the clearance behind the seats and the placement of the buffet side boards port and starboard. The beam of the boat is 28’, so there was plenty of width for this dining area, even with the wide side decks.

Galley and Beyond

The galley space is fairly standard for this type and size of yacht. There is a large stove with oven in one section and refer/freezer in another. Counter space is limited, which is an occupational hazard. The companionway leads to the crews' quarters where there are two more refers/freezers, the washers and the dryers. (You can never have enough freezer space, even on a 142-footer. Remember, there are 18 people aboard.)Forward is the owner’s stateroom and suite. When you have a vessel large enough to have the owner’s suite on the main deck, in our opinion, you have arrived. The his and her head with circular shower is forward and both partners have their own desks, chest of drawers and walk-in closets. This whole design is typical of traditional yachts in this class.

The accommodations deck.

The Accommodations...

The spiral staircase to the accommodations deck keeps within the theme of the round dining room table and the rounded bulkheads there. It leads to a large foyer below and the four guest staterooms each with en suite heads. These guest staterooms are all large by any standard, thanks to the 28’ beam. Crew quarters are forward along with a galley and lounge/settee. Vessels of this size usually have seven or eight in the crew – Captain, First Officer, Engineer, Chef, Sous Chef, Mate, Stew, and often a second stew or mate. The captain’s cabin is up behind the pilothouse helm. In this design we find four crew cabins below, each with two bunks. Obviously the senior crew will get the larger cabins and the swabs are forward in the fo’c’sle. With seven in the crew, the engineer, first officer or chef might rate a private cabin. Aft is the garage for the tender on the centerline and there is plenty of room outboard for scuba gear, air compressors, furniture, fenders and water toys.

The Pilothouse and Sky Lounge Deck.

Pilothouse, Sky Lounge, Aft Deck II

Once you get beyond 115’ or so, a raised pilothouse design looks odd, and it is far more pleasing to the eye as well as for the guests to have a full deck with sky lounge. We like the pilothouse in Sea Owl II because there are three chairs on the bridge, a long bench seat with tables aft for the spectators, and a captain’s work station to port. The sky lounge is large and, in fact, wider than the saloon because there are no side decks. Aft we find another round table and more seating in the sun. What is different about this deck is the addition of a large pantry, complete with dumb waiter. Look closely and you can see it located abaft the captain’s cabin and forward of the sky lounge on the port side. This is a terrific idea, and with so much room, why not?

The Tri-Deck Flying Bridge

Obviously this deck is the icing on the cake for any yacht no matter that it is 142’. It is well laid out with plenty of guest seating port and starboard. There is a hot tub aft and a head tucked into the port pylon. What is not obvious, but a nice aspect of a boat of this size is the fact that the engine room air intakes are located on this deck which keeps saltwater and mist out of the engine room and the dry stack exhaust is here as well.

Power & Low Carbon Foot Print

Given how big and heavy the boat is, her power is very much on the light side, and that is one of the endearing aspects of this vessel – her relatively small carbon footprint. She is powered by twin Caterpillar 3412E DITA diesels developing 1,000-hp at 2100 rpms. That is less horsepower than most builders put in 60’ sportfishermen weighing 10% of her 650,000 lbs. (295,454 kgs.)!These are what Caterpillar calls “legacy” engines, which means that they no longer build them, but some of their distributors do. In the case of the 3412E, the engine weighs from about 5600 to 6257 lbs (2545 to 2844 kgs) compared to 3700 to 4200 lbs (1681 to 1909 kgs.) for the C-18 ACERT Caterpillar diesel developing about the same horsepower.Since this is a displacement vessel, the extra 3800 lbs. will not have much affect on speed or fuel efficiency, but the older, heavier engine will undoubtedly be more reliable and have a longer life. This is a very unusual engine selection and speaks volumes about the owner. The fact is that this vessel will probably be run from 11 to 13 knots at fuel consumption levels similar to 60’ convertible going not much faster -- and this is one of the things than makes displacement boats so attractive. She can carry up to 15,641 gal. (59,435 l) of fuel which gives enough range to cross any ocean, which clearly she is capable of doing. For those among our readers who are curious as to what an aluminum vessel such as Sea Owl II might cost, the answer is north of $20 million. Burger is located in the U.S.A., which these days is nearly the cheapest place on the planet to have a quality large motoryacht built.
