2001 Bertram 510

A friend of mine owns an 05' with same engines.
We cruised on his boat last summer.

Your assumption about consumption is correct.
The best speed/RPM/fuel ratio on this boat seems to be 1800/1850 RPMs with some 23.5-24.5 knots (clean hull), means 200/220 liters per hour. Those 100 RPMs are not worth the speed against fuel burn.

Sea keeping: she's a tank; just some station wagon effect in cockpit, particularly if you have a cockpit sunshade.

Costs: pretty close the seasonal service, would have to add some 10K on a 2000hrs range. Huge of electronic control units very expensives. As far as Mans: Very good engines but also big smokers.

Still trying to make me liking the shape of the boat from bow to deckhouse.

So if I do the most basic maths, and having owned the "latest" MANS in a 48 UNIESSE (which I sold before the MAN warranty expired) it seems to me that the savings on fuel are ABSOLUTELY negated by the maintenance costs on the latest technology engines?
Not to mention the lack of support which is a big issue for owners who use their boats for cruising to ports that are not within the city hubs.
Did we not choose DEISEL engines for their longevity and low maintenance costs?
Seems to me that the manufacturers have worked out a great way to keep the cash flow positive by UP selling the community a high cost maintenance engine when the original ethos was precisely the opposite.

Kaufe,

good point

RT 46

I used to run a 51 Bert, and believe it was a 2001 or 2002. Fuel burn at cruise (26 kts.) was about 85gph. Did Not Like the boat.
1) We had a vibration in the stbd motor that we couldn't get rid of despite several realignments and mechanics checking. That could be just this boat however.
2) I found it's seakeeping lousy. In a 5' head sea she slammed so much that the owner was injured and it had us down to 10 kts. At rest she was a seasick machine. rocked like hell in a 3' sea.
3) we had glass problems all over. Lots of stress cracks on the deck and bridge.

I used to run a 46 from the 1980's. Now that was a tank. Had that out in well over 10' angry seas and felt completely secure.

Nice 28.

Mercruisers or yanmars?

28's have their issues (a hint of wetness on a rough day), but they do get you home on a bad day.

Very nice. Did you put in the 170's or 230's?

I had one with the 170's and they ran like a toyota. Put 1000 hours on them without any issues.

Where are the outriggers!

Scrumpy

Bas you own the Queen of Rock and Roll!
I remember when I was on a friend's of mine 28, we had to grab everything, even if a dinghy was riding by.

On the other hand, back to the 510, with all the due respect to NYCAP, one of the Pros here,
I agree in head seas you have to throttle down, but this is what has to be done also on a 50 Hatteras.
I would guess that is more related to hull length.

While if we talk of Bert 46, let me say a couple of things:
A) Dave Napier the guy thanks to whom the term "Bertram weather" was coined and Designer of the 46 hull
B) Lower speeds, different boat planing also due to engines weight, huge of hull weight and fuel burn.

Still thinking the 510 is a good boat IMMO.

While I agree the hundreds series, 450/510/570 and last but not least the 630, represented actually the end of a Legend!

Can't remember the name of the Designer

My friend put on her no less than 2K hours during the last 7 years, with not a single major issue.

He only had to change a couple of electronic control units; let me say, due to some shore-power overload may be, when he was cruising in deep South Med.

If you can have engines surveyed carefully, including fluids analysis, prior to a possible purchase, big issues stay out of the door.

Those hrs mean they should have at least made a major haul

Happy to give a view on the 36, as I had two 28's, before getting a new 36 which i had for 5 years.

It may mean that they are ready for a major overhaul soon and that the new owner is going to have that very expensive privilege.

I had my Bertram 54 tied to a mooring and we were having fun with the Bertram 28 too ... So we brought the B28 next to the B54 using large fenders as a precaution. A passing boat left just the right kind of wake that had the B28 rock over so hard that the radar arch on the B28 almost smashed through the side salon window of the B54 .. It was that close. The upper (top of B28 salon) rub rail did hit the side of the B54 and exploded with fiberglass going everywhere. The force of impact was extreme. No damage to the B54 but that started the process on the B28 where I decided to replace the salon window glass and frames, glass over the front windows and do an entire exterior paint job. It's going to be a 2 year process and I'm approaching one year this summer. Got her sanded down, glassed over the front and new custom glass (sealed) on the sides.

Lesson for all Bertram 28 owners ... don't tie up or let anybody tie up tandem as you will all regret it.

The 54 Bert is a tank!
