It was my engine battery - and when I say flat I mean...

In Response To: My Optima lasted.... (Dave Westsail 42 Elysium)

too low to start the engine - not sure what the actual voltage was at that point, but it charged right back up (this happened on at least two occasions when we had an electrical gremlin - since resolved) I can see no difference in the voltage readings from new till now as a consequence. We have a smart charger and I make it a point to top up the batteries on a monthly basis. An interesting point made by an Optima tech at one of the races was that it would not hurt to EQUALIZE these big Optimas about once a year. He said this was not the official company position but in his lab testing it had proven beneficial - I tried it for two hours on the start battery last season but couldn't tell any difference one way or the other - might have needed more time.

Probably more likely 3-7 years, depending on use/care and charging system -- Larry - DH -- 11/4/2011, 11:35 am
There's ten years on the Optima 31's in our old boat... -- Ron Chappell -- 11/4/2011, 6:13 pm
We had a Optima as an engine start battery -- SG -- 11/4/2011, 7:57 pm
To clarify: I replace the Optima with another brand new one. (And I added another one as a dedicated Gen start batt -- SG -- 11/4/2011, 8:06 pm
As it got older, could you see any difference in it's actual condition? -- Tom Young -- 11/5/2011, 4:40 am
WIth a conventional lead (wet cells) battery, you really should equalize them or they'll sulphate. -- SG -- 11/5/2011, 5:43 am
5 months(I'm sailing this weekend ) But the starting battery is different test. -- Tom Young -- 11/5/2011, 6:15 am
Using an electric windlass without the engine on is not good for the windlass (aside from the battery issues) -- SG -- 11/5/2011, 7:42 am
I never use the Windlass unless the engine is running ... -- John -- 11/5/2011, 8:54 pm

Just switched away from Lifelines -- Dave Westsail 42 Elysium -- 11/4/2011, 2:20 pm
Lifelines (and any AGMs) need to be fully charged periodically... -- DDW -- 11/4/2011, 10:06 pm
Lifelines are different.... -- Dave Westsail 42 Elysium -- 11/5/2011, 5:26 am
You should not be equalizing Lifelines batteries every month... -- DDW -- 11/5/2011, 10:24 am
Lifelines engineer disagrees... -- Dave Westsail 42 Elysium -- 11/5/2011, 11:40 am
The Lifeline - Manual makes it clear, it's dependant on a number of factors -- SG -- 11/5/2011, 2:29 pm
Our experience is pretty positive for Lifeline's -- SG -- 11/5/2011, 3:17 pm
I agree, six months maybe or... -- Ron Chappell -- 11/5/2011, 3:17 pm
Manuals are a function of... -- Dave Westsail 42 Elysium -- 11/5/2011, 5:08 pm
The Lifeline Manual was updated in July of this year. -- SG -- 11/5/2011, 6:31 pm

Two big -- cchesley -- 11/4/2011, 9:14 am
Pretty big list this year -- Max Fletcher -- 11/4/2011, 10:08 am
The biggest ones were new holding tank and new broadband radar/c-p/fish-finder -- Larry - DH -- 11/4/2011, 10:39 am
You could eat off that engine - nice -- Max Fletcher -- 11/4/2011, 11:15 am
Hell! You could eat off those holding tanks, even the old one (Though eating off them is probably not recommended) -- Blye -- 11/4/2011, 11:23 am
The best part of that job was the tank had clearance past the engine -- Larry - DH -- 11/4/2011, 11:33 am
I took my CS holding tank out in 1997 and replaced it with a "bag" HT -- Blye -- 11/4/2011, 11:58 am
My summer was spent putting an addition on my house... but there is a serious boat component -- Blye -- 11/4/2011, 11:18 am

holding tank -- Ron -- 11/4/2011, 12:24 pm
Nice looking engine room. -- GeneC -- 11/4/2011, 12:02 pm
Love those boats. I hope you post more about your upgrades Ron. -- Tom Young -- 11/4/2011, 12:22 pm
under glass -- Ron -- 11/4/2011, 12:53 pm
Wow, all you need are probe points... -- GeneC -- 11/4/2011, 1:03 pm
Great! Good use of the stuff. -- Tom Young -- 11/4/2011, 1:33 pm

Here is a picture of the boat.. -- Todd D -- 11/4/2011, 1:21 pm
Nice work Todd, I bet you can't wait for spring. -- Tom Young -- 11/4/2011, 1:31 pm
Is that where the engine tops out, Todd, around 9 knots? -- Paul D -- 11/4/2011, 1:22 pm
Top speed was 9.1 knots at 3,150 rpms... -- Todd D -- 11/4/2011, 1:25 pm
How are you calculating burn rate? -- Larry - DH -- 11/4/2011, 1:38 pm
I have a plastic tank that I can see the side of... -- Todd D -- 11/4/2011, 1:44 pm
That would be really nice info to have -- Larry - DH -- 11/4/2011, 1:53 pm
It is remarkedly simple to calculate fuel burn versus speed if... -- Todd D -- 11/4/2011, 2:01 pm
How would you do that? What info is needed? -- Larry - DH -- 11/4/2011, 8:28 pm
For a first approximation, waterline length and displacement -- Todd D -- 11/5/2011, 5:42 am
The calculations are a bit too involved to write up here... -- Todd D -- 11/5/2011, 8:11 am
I can give you everything now, but BWL -- Larry - DH -- 11/5/2011, 9:48 am
corrected LWL to 36.75 feet in post above -- Larry - DH -- 11/5/2011, 9:59 am
Larry - here is a crude estimate... -- Todd D -- 11/5/2011, 12:31 pm
By the way... -- Todd D -- 11/5/2011, 12:33 pm
When you have strong winds and seas against you, can you be overpowered on a boat? -- Tom Young -- 11/5/2011, 4:20 pm
There is only so much power you can use... -- Todd D -- 11/5/2011, 4:46 pm
Then why do many sailboat designers spec larger auxilary engines,... -- Tom Young -- 11/5/2011, 5:00 pm
Larger engines are put in to make ignorant buyers happy... -- Todd D -- 11/5/2011, 5:12 pm
I think you can get Larrys boat with 150 hp Todd. It'll plane I imagine. -- Tom Young -- 11/5/2011, 5:18 pm
A planing hull is a very different beast than a displacement hull -- Todd D -- 11/5/2011, 5:38 pm
Thanks Todd. It doesn't match the real world though -- Larry - DH -- 11/5/2011, 8:20 pm
Also, we average about 1.25 GPH at 7.5-8 knots cruising speed -- Larry - DH -- 11/5/2011, 8:24 pm
It is clear that your hull is semi-planing or planing in design... -- Todd D -- 11/5/2011, 9:07 pm
Thanks Todd -- Larry - DH -- 11/5/2011, 9:38 pm
I have a friend with a 40' tri, he once couldn't turn it into the wind under power. -- Tom Young -- 11/6/2011, 2:56 am
My boat turns on a dime, but only with the centerboard down. -- Larry - DH -- 11/6/2011, 7:48 am
What auxiliary do you have? 4,000 RPM? -- SG -- 11/6/2011, 6:30 am
