Twin 5.7 Horizon VD's
Hello forum members, I thought I would take a moment to fill you in on my first impressions of the 2007 Sea Ray 320 Sundancer. There are others on the board who surely will contribute their first impressions too and this hopefully will make for some good reading.

My new 320 which was put to water on Friday the 23rd of March is a decently equipped boat with notable features including twin engine 350 Horizon V-drive power plants, bow thruster, soft top, central vacuum, Raymarine GPS-chartplotter-radar, wide-screen TV and cockpit icemaker. On the next day, Saturday, I spent time with a certified 100 ton Captain which my dealer provided for orientation up to 8 hours though I only used about 4 (the other 4 I may or may not use). Then on Sunday my family and I went out for a 2 hour round-the-island cruise to exercise the new boat.

It is important to know my background just a bit; I came from a single engine 280 Sundancer and previous to that a 220 Sundeck so I have never piloted a twin engine boat before for any length of time. What a difference! In close quarter maneuvering there is no doubt the twins have a major advantage even without the bow thruster. The 320 was a pleasure to operate and the inboards were smooth as silk. Strangely enough I was surprised that the boat did not feel very big, certainly not what I thought it would feel like stepping up from a 280 that is. In fact, the overall feeling was that of still being on a pocket cruiser; up until the point of running her on plane at cruise. You knew you were on a big boat then!

My dealer in Portland (Trudeau’s Sea Ray) did an excellent job preparing and fitting the boat. We only had one real issue last weekend and that was the GPS stopped working. Come to find out it was a bad antennae cable connector and they promptly replaced it. There were a few other issues like the soft top was damaged from shipping but that is on order and there were several blemishes, but nothing major. As I mentioned in a previous blog I had the bottom repainted with Pettit Trinidad SR (2 gallons) because the factory bottom paint is known to be of poor quality and longevity. We also added the upgraded deep cycle gel cells (all 4) which I hope will be worth the additional cost over time. All in all, the boat was wonderfully built by a crew at Sea Ray that obviously takes great pride in their workmanship; I am very impressed with the fit and finish (and I “really†looked hard for poor quality)!

So what did I like best about the boat? This will surprise you I am sure; it is the soft top. Yes, that is the coolest part of the boat by far. I love the additional length front and rear, the wonderful look, the “no rattle†construction, the clean visibility without any stanchions, the 3†drip overhangs all around and the way it leaves more exposed white arch over the top. It just looks fabulous and for the ~$2000 retail up-charge it is worth it! Granted I live in rain country so that may be partially the reason I love it so much, but boy do I love it! My second favorite feature, yep, you guessed it, the bow thruster. And the reason for that is probably more than anything else, is that I love toys. Do you need one; no, but do I like it, heck yes! I suppose I should add a third item here too that I like, and that would be the ultra smooth shifting ZF transmissions. They are so silky smooth I can only describe it as somewhat sensual. The amazing low end torque too isn’t bad either. Oh yes, I just have to boast about all the great storage; thank you Sea Ray!

What’s on the flip side? What are the things I already dislike? That is easy and the number one item is that cabin sofa and table. Give me a dinette anytime please, and in fact I dislike it so much I already am thinking about paying a custom shop to take it out and build me a dinette. No other item on the boat comes close to the cabin sofa. Another area I immediately recognized as a negative is the mid cabin lounge. Not that I don’t like it but that it is not long enough for my 5’11†body to sleep on because it is too short to lay down straight. The new 310 Sundancer has a longer one. I guess the large fuel tank is what kills that spaces potential. Finally the other item of contention is the disappointing built in coffee pot (slash microwave). That was a huge error in judgment if you ask me. First of all let me tell you I do not like combo appliances (esp. tv/DVD’s) and this is a really bad combination.

Well that is more than enough for one blog but I do plan to write an ongoing string around the same general subject and another where I compare the 280 Sundancer to the 320 titled “Do you really need to move up?†My sincere thanks to Sea Ray for building what seems to be another truly outstanding sport cruiser and one which I am sure will give me, my family and friends years of pleasure! I never would have believed it, but Sea Ray kept me from jumping over to Formula (now there is a feat).

Cheers Mates,

Marqus
 
Well written Marq and I enjoyed all your observations. I am looking forward to what others have to say.

I hope you really enjoy the new boat. :thumbsup:
 
Thanks, great info. Sounds like a great boat and dealer :thumbsup:
 
I'm a little confused by your lack of space sleeping in the mid cabin. I'm 6' and I could not touch the end with my feet sleeping in my mid cabin area and my boat has a foot less beam than yours.
 
Wow what a great post! Congrats on the new boat and thanks for sharing your experiences so far. I especially love hearing your impressions of the soft top. I ordered it on my 320 and thought the look and sturdy mounting was worth the price. I'll know for sure when I take delivery next month. Others on the forum have expressed a negative opinion so its nice to hear the voice of experience!

Look forward to reading more when you can.
 
Marq....your going to need a bigger boat! :smt043

Nice write up, make some addendum's over the next couple of months. :grin:

Glad you like your boat. :thumbsup:
 
Hey Marqus -- one thought on your mid cabin. The dealer showed me how the starboard side seat back is hinged and folds up. This gives you several more inches of room for laying down. I'm also 5' 11" and I could stretch out fine.
 
Wanna trade your 320 for my 240? :grin:


Congrats on your new boat! :thumbsup:
 
Marqus-

Congrats on the new ride. A few observations after first year on our 320. We also went from a 270 w/ single 7.4 to the twins. First of all " Holly sheep dip bat man" we underestimated both the cost of fuel ( $3.50/gal ) and just how much we would be running through her. Its was like Christmass in July.
We too were a little confused by the sofa / table below. As is turns out 75 percent of the time we end up out back for eating. It's good for a conversation pit and the table a plus for appetizers and a like. The mico/coffee combo... We are not coffee drinkers so the coffee pot has become another storage spot for us. We changed out the face of the fridge a brushed S.S. panel to match the Micro. It looks good.
One thing I'm going to work on this summer is the trash can is in the storage cabinet under the sink. Not a big fan of storing much of anything along with the open trash. I'm going to frame it off and put a drawer slide on it. This will keep the trash seperate and we will be able to utilize the balance of the cabinet. Look at his and let me know what your thoughts are.
The mid cabin Lounge, not my choice of areas to sleep in. I prefer the v-berth or the couch witch I suite me fine. The mid cabin is great for the kids. We have the flip down TV / Entertainment system back there with the remote head phones. One movie, they close the curtain and we pretty much do'nt know they exist!

On our original complaint list was the TV antenna reception or lack there of. Our marina does not have cable so this became a challange for the eveing news. We ended up putting an HD reciever on board with a small directional antenna. We were amazed at the picture on the bulk head 26" lcd. I also found out our area has several full time weather cahnnels with live 100 mile
radar. A great tool before we head out.

We do not have the thruster but learned quickly to practice with the twins and ended up with great confidence backing in any slip by myself.

As far as fit and finish. I preform some quality work for Brunswick from composite construction and adherence to the laminate schedules to fit, finish and funtion. They clearly missed the mark on the fuel sending unit. Ours displays throught the Smart craft monitor and never worked well or at all. On long trips we learned to guage usage from experience. I learned at the plant they knew of this and were putting ultrsonic sending units on the new 07's. Other than one chip on delivery we were satisfied with boat finish.

P.S. I am disapointed with: the side SeaRay bubble decals versus the old chrome SeaRay logos they use to use and the lack of light over the galley counter.

That is my 25 cents worth!

Yes, the lack of light over the galley work surface is not acceptable. 1 AC light which is offset, no DC lights and the sky light. Very poor lighting.

After 11.5 hours on the clock, 65.5 gallons of fuel burned, .7 average MPG at a lowly 21 MPH average; yes, I would say she is a gas sucking hog. Watching the fuel needles drop sure makes me miss my 1.94 MPG 280DA.

We sure do like the room and storage though!
 
On the GPM subject- the 6.2's pushed us 24.5 mph and was at .94 GPM. We found that to be our cruising / comfort speed. We can do better ar 21-23 but on long trips grew to be comfortable with .94.

So far we have nothing to complain about other than the short berth. If I really streatch my feet go over the edge.

I said it before and I'll say it again, this boat needs the 6.2's. Even then you're looking at 3800-4000 rpm for a reasonable cruise speed of 24-27mph. The 350 mags simply cannot match that with those small 3 blade props, unless they are coupled to Bravo III's.
 
Marqus - Congrats on the new boat.
I'm sure your mileage will improve with some break-in time on the motors and running gear.
My best mileage comes in around 3600 - 3800 RPM at around 25 MPH and 26 GPH fuel burn. I feel that is reasonable.

In fact the props and gearing are exactly the same with the 350 or the 6.2 motors. All things considered, the 350 is the better buy IMO, and they are practically bullet proof. The 6.2 gains you a few hundred rpm on maximum top end, but who cares.
Now if you could get inboard big blocks in the 320 that would be significant.
 
I have a 300 with IOs, so I am able to get up and out of the plow mode and typically cruise at 30 mph. If I dont go 30, I chug along at 1000-1200 prms and about 6 or 7 mph. I think both of these options will get me the most distance for gallon. I never drive at speeds between these for very long.

I dont think your 320s are up on plane enough at 20 mph so I would not cruise too long at that speed. Not quite on plane is inefficient in any boat.
 
I agree, and the running angle on the 320 seems steep. Going to instal an inclinometer. Now that the boat is past the critical 10 hours, I'll run here at around 4K RPM's which should give me 27MPH.
 
No doubt the 320DA with v-drives tends to be stern heavy.

I have found a bit of tab helps quite a bit to both lower the bow on plane and improve performance. It's a lot more obvious with the digital tach readouts on the Smartcraft gauges - I can add some tab (both sides) and watch the RPM's increase 25-50 rpm. I keep doing this (add a bit of tab, let the boat settle a bit) until the RPM starts dropping when more tab is added.

Around 3800 rpm and beyond, the boat flattens out quite a bit on her own without using the tabs.

I agree CJ, and I guess that's the point. You need upwards of 3800 rpm to generate enough thrust with the 350's and inboards to get the most efficient running angle, whereas with the bravo III's 3500-3600 rpm gets you the same result. Of course the IO's have the higher maintenance cost, so it's a matter of compromise with both setups.
