Default 44 Ocean SS real world performance?

Sea trialing a 44 Ocean SS, 6-71TIB later this week. Boat has a fresh bottom (blasted / blister repairs / barrier coat / bottom paint). Engines 500 hours SOH, (were maintained by one of areas best DD mechanics until retired). I am looking for 27-28 kts WOT and 24 kts cruise around 2150, full fuel 6 people on board.

Am I being realistic?

My Viking runs the same cruise speed / RPM as it did at the factory test (I have the original test logs) so I expect the boat should be able to run close to the factory brochure performance, after adjusting for the heavier weight of full fuel and crew from the test report half fuel and I expect two people.

Thanks - Greg

Thanks.

The owner took the boat home from the bottom work and exterior hull inspection on Friday. One motor only pulled 2350, but it also only ran 24 kts. If both motors were 2350 I would still have expected 26 kts or so. Owner seemed a bit shocked when I said I expect it to run close to 30 kts. Props are 24 x 27 unknown cup.

A very good DD mechanic (my surveyor actually) is going to see what is up with the one motor on Tuesday. Anxious to see what turns up and if they can fix in time to keep survey/sea trial schedule or causes another delay. This has been a very long, slow, stressful process (and as an engineer I don't do uncertainty well).

We had a 1989 44 Ocean with 6-71 tib. I don't recall the props but we cruised 25 kts at 2100-2150 rpm normal full load (not overnight canyon load). Wot was 30-31 kts full. I always turned propper wot rpm even with full load so it was not over propped. Great boat and engines just don't overprop and the engines will be good. Oceans claim to fame back then was all their boats were 30+ kts so expect 30 kts unless something is off.

Thanks sfaatz. Just what I was looking to find out.

vitalsigns. Prior owners of my current Viking were as anal as I am, I have paperwork back to the original invoice, test run logs and QC check list.

Boat failed survey, never made it to sea trial. Back to looking. Thanks all for the information.

What issues came up on the survey? I have a friend looking at Oceans right now, would appreciate knowing what you found.

This boat did not have any of the typical issues of water leaking around windows or visible inside the cabin. The cosmetics inside and out were extremely well maintained. Initial inspection was much better than a prior 46 had looked at, which was obviously wet everywhere. I had not been able to explore the decks prior since it was raining when we were able to take initial look at the boat. Later learned the exterior teak was so nice since owner replace it all when Ocean closed a few years ago.

Several levels or problem caused us to stop the survey very early in the process:.

First was the bottom half of main stringers tested wet the length of the engine room and under cockpit. We didn't ask to drill to find the depth of moisture due to subsequent findings. It could be from prolonged water in the bilge migrating from the limber holes, but did not investigate further to see how extensive any actual rot was.

Second was high moisture and numerous soft spots across the cockpit floor. The owner had previously had the factory teak floor removed and a "couple" layers of fiberglass added. I think that took away most of the original strength in the floor, there is little stiffening structure below the floor, so it flexed excessively since. (disclaimer I design composite structures for aircraft, and I wouldn't expect that thin a floor after the teak layer was removed to be sufficient.)

Final straw when stopped survey was when all of the foredeck tested wet, and soft spots along the outer walkway the full length of the bow rail area. Much softer near each stanchion and foot or two away. Near the anchor line hawse pipe you could flex the deck visibly (about 1/4") pushing with just your toes.

Expect it all could be fixed but I'm not interested in having a boat in the yard for months instead of using it.

Final comment, I believe from statements and reaction that the owner knew of all the issues except the main stringers (found later it had failed a partial survey before) but didn't let the current broker or myself in on his secret.

I'm still interested in a 44 or 45 Ocean, like the layout and performance, but this candidate was a failure.

Greg-

Great tips- thanks. I am toying with either an older 44 Ocean (most are crap like you surveyed) or a new(er) 48 Ocean. best of luck in the hunt!

I looked at a 1999 48 that had lots of water problems (mold) too. I like the older teak cabin boats, but they are hard to find. Hanging on to my 1987 Viking 35 until I find something in as good condition.

You Ocean 44/45 guys should consider the 43SS, production 2000-2005. Many build/quality improvements, fast and economical hull and 4 cycle power - either Volvo 480 or the preferred Yanmar 500. Factory provided numbers below. My 43SS is in Plymouth, MA

and for the OP... here are factory numbers for the 45SS with 6-71TI power. The 45 replaced the 44 with some hull improvements, but should be very close

Thanks. I also received link to data for the 44 MV, same hull and power, only about 1 knot slower.

This is very sound advice. The difference in design, manufacturing techniques and engine choices really make the 43SS a very substantial upgrade over the older model 44/45. The rough water ride of the 43 is light years ahead of the 44/45. I know it may be a $$ issue but it may be worth a look at the 43. My dad has a 2004 43SS with 500 Yanmars and it is a very nice boat especially for the money. Fast, efficient and a decent ride in choppy seas.

And I will add my dads boat is 16 yrs old now and he cruises at 25 kts and hits WOT of 32 kts any day of the week. I don't recall the rpm's other than they are much higher than my Cats.

The 43 salon looks smaller than the 44 but I've never been on one. Could you tell me the length of salon on port up to the galley, and then including the galley; and length on stbd with the dinette area?

I looked at a 48 but its really too big for my dock (46 ft long) and I don't really need/want the third cabin. I'd actually like two cabins with one head and put the extra space in the salon but no one seems to make that arrangement.

The 43SS salon total length is 13'-6" both P&S, including the galley
Galley counter to counter is 6'-3"
Salon length less galley to port is 7'-3"

Thank you very much. The galley-up does use up a lot of salon space compared to the 44. I expect the 45 is closer to the 43 than the 44 since it has the same basic arrangement.

I had the 671 tibs in a 43 egg harbor. The engines are not known for longevity as they are a lot of hp worked into the original smaller motor block. I remember mine had lower hours and I was told they had some decent wear on them. If your looking to repower it then its a mute issue. I know nothing about the boat but i do know my experiences with the motors. They were so smokey on startup, hard to cold start and always found oil dripping somewhere at one time or another
