Having owned the 450DA three years and seeing the intrest these boats have I thought i would give my very and i do mean very unexpert or worse review. First a little history. We moved up from a 2005 Glacier Bay 2685 that we had used for two trips to the Bahamas. Moving up 19 feet to such a big boat was scary. We had an epic 6 month or so boat search that included alot of help from FrankW and others. We tested several and i mean several SR. 40 TO 50 feet. After all the crying we selected the 450DA. From stern to bow alittle comentary. The swim platform is big and low to the water and that is good. We put hurley davits on with a 10 foot two inch 8.8hp dinghy and it works like a charm. The fuel, water and power cord are located in easy to get to locations around transome area. Storage area is good size and deep enough to throw a bunch of useless stuff in. The cockpit area is large but i donot like the round euro looking seats. They are fairly comfortable but could be better. Sink is on port area. Dont like that faucet. Carpet in storage area under sink was a bad idea. The engine hatch area is good and pretty easy to go up and down. The engine room steps are good. Engine room is GREAT. Lots of room and can get to almost everything easily. I have Cat 3126-420hp and love them. Back out of the engine room to helm. My boat has a canvas design that goes up thus making head room very, very spacious. I know most dont have this and some complain of tight head room. The design on mine makes the area very large. The helm area is good, seating comfortable. Gauges in good position except the chart plotter. I like mine to the right and closer to eye level. We modified ours and its all good. The viewing from the captains seat is good. Every thing is easy to get to. Not much i would change. The door leading down to salon is large. The steps are good. On the left going down is the electrical panel. This is well thought out and easy to use. My salon seating is AWFUL, DID I SAY AWFUL. You have to 18 years old or a gold medal winning gymnast to sit there for long. The tv is above refrigerator and can be a neck sprain. We are going to do some mods in this area soon. We have the washer/dryer combo and my wife loves it. Was a must have from her during our boat search. The galley is all good. Not much i would change. The main Stateroom is all good as is aft stateroom. Bathroom for master stateroom is very large easy to move around in etc... Very nice. Other small head is nice but shower is not seperate, so alittle wiping up after the shower. No big deal. I really like our little aft compartment. Lots of storage, more comfortable than you would think. We have the maple(light) interior and its easy to clean, etc... The storage areas in salon are easy to get to and fairly large. Thats all good. Sump pump is in salon storage. Very easy to get to. Fresh water pumps are in aft area under bed. Overall the living area is good with everything easy to get to. Nothing I would change but the seating area. I will do another PART2 review about bow area and mechinical latter.
