Stabilizers for Blue Angel, engineering question

[BartW]

Bart, I find that if you drink the right amount of rosé you don't notice the swell as much in SoF

and if we drink a bit more of that pink wine in a swell, we will have lots of fishes and sea live under the boat,
which is a good thing for the divers

 

[wakeup]

now you are talking...

 

[Pinnacle]

Fantastic thread, Bart. S is reading it with much interest!

 

[jfm]

A fan and a hose as used for your genny ventilation in M2 could be a very cost effective solution

Hmmm. I'm not sure. You have to have very sweet smelling bilges in order to cool by venting into the accom space

not a major problem, imo
if really needed, I could bring the hose up throught the bathroom side wall locker (SB) and the dressing room (P), through the saloon floor, and under/behind the sofa's through the wall, arriving outside in a vent louvre above the side deck floor.
(or probably other more nicer solutions)

ooph; now I have to consider every word I type

Yeah that will cure the smell problem but the fan has to suck the air from the bilge to create the airflow over the hot motor. That will create a much less focussed and lower speed airflow over the motor than a fan that blows onto the motor

I don't see the problem J, there could be a hose on both sides of the blower,
blower in a nearby position,
extraction hose entrance, right in front of the electric stab motor.

I think there are a lot more difficult challenges on this project then this cooling, don't you think so ?

 

[Piers]

good advice Piers,
will show this to my wife when she sees the bill of the stabs

Hi Bart. It's always so interesting the way that, even in total flat calm oily seas, if I turn the stabs off my wife is shouting for me to turn them back on within 30 seconds - or soooner - how does she know????

Question:

I would like to know the thickness of the GRP / bottom of the boat,
how to measure this without a liftout ?
I have scuba gear to dive below,

Canados workers tell me that its thicker and stronger than modern GRP boats,
but they don't know how much.

If the bow has the same thickness as the bottom, who knows ?
I could measure the thickness,
in the anker locker draining hole.

Is Mrs Bart reading this? If so, how long do you image staying alive?

 

[rafiki_]

Bart, really difficult to say remotely. Safest way is to remove a seacock when on dry land, as I'm not sure there are a pair of callipers big enough to get over the gunwhales. The Canados suppliers should know, and I sure you have good contacts there. Failing all the above, if you know of a similar size/weight/type of boat that you can access, yours will not be too far away as an estimate.

Is Mrs Bart reading this?

when sitting behind my computer I alway's tell her I'm working ;-)
she never bothered reading the forum, she thinks its boaring
she is usually bussy working (4 kids), or painting ;-) , watching TV, or reading 50 shades of grey

Someone once told me..
"Never try and understand women. Women understand women, and they hate each other.

 

[BartW]

I've got a few PM's and e-mail's regarding the gyrostab option,
just to confirm that I have looked at this option, and talked with the people at Metz in Adam,
we DO need 2 x 8000's for BA,
this is 2 x 1m3 space which is very difficult to find in the e/r nor the lazarette, unless a very huge rebuild,
and even then, I will loose lots of usefull space and acces that I like right now.

Difficult. Is there a straight, not elbowed, seacock nearby?

1. Remove hose from seacock, open seacock, insert a depth gauge with hooked end (home made from sheet metal or sheet plastic or 5mm plywood; the hooked end is so you can feel the outer flange of the seacock and hook under that then pull up). Mark or scribe the depth gauge, then remove it and close seacock. You'll have a few gallons of water to clear up, sorry, though you can hold rag over the open seacock to resist the flow while you are doing the depth gauge work.

2. Then measure visible depth of seacock inside hull.

3. Then dive down and measure the flange thickness of the seacock.

4. Then apply arithmetic to the 3 numbers, and that gives you your answer to high accuracy.

You cannot measure the hull thickness elsewhere, eg anchor locker. 95% certainty it will be different

Brilliant !

there is a big straight seacock for "Toilet direct to sea outlet" very close.
I'm sure it doesn't have a grill.

I'll go there next week and take a Knitting needle with me

Maybe you could use ultrasound to measure the hull, non destructive and you could measure anywhere you like.
