When I was sailing dinghies and every time I bought another one, I always capsized and rolled it to see if I could get myself out of trouble... I guess this thread is a sort of virtual equivalent.
I am not planning to roll my boat, but just thinking:
- Even though most of us have secured our batteries, do 'normal', air vented lead acid ones, like Trojan T-105 many boats have as house batteries, leak acid when upside down or when tilted at 90 degrees? - - And if so, how much, just a few drops, or the whole content?
Hehehe, have AGMs now, can even be mounted upside down.
Still on batteries, there is one reason (keep centre of gravity low) to mount batteries as low as possible, and another reason to mount them higher in case of a rollover and coming the right way up again:
- There will be some salt water
sloshing around and when the batteries under the floorboard are awash....., they do not provide much power if any.
Still thinking....about engine
now, when in rollover:
- If the engine
is running (and staying in place), lubrication is next to nil if the engine keeps running when the boat is on its side or upside down, hmm, soon the fuel pump
will suck air and then stop? Will that be before any damage can be done?
- If the engine is running or not, and water sloshing around (after the boat has come the right way up).... how is the air intake protected from water ingress.. Water in the cylinder(s) is one sure way to damage the engine irreparably.
Still thinking.... about tankage ie diesel:
- Will they leak from the airvent, maybe OK if the airvents are outside, or will sea water then enter the tanks
Still thinking..... about crew being in the cockpit
- Hopefully all will be clipped on.... but can they be easily undone if the tether is not long enough?
- And when you undo the clip, can you hang onto the boat, or be swept away?
Still thinking..... about mast
- How soon would they fill up with water? And I guess a 15 mt mast
will weigh then an extra 500 kg (that is when one tries to right the boat and trying the get the mast (then level with he water) out of the water).... hmmm that is lot of leverage.
Still thinking..... let me check the weather forecast
for this afternoon:
- 10-15 knots of wind
, with 20 knots in gusts, seas to 1 meter....., swell at 2-2.5 meters:
I am staying home!!!!
Maybe those with actual rollover experience could share that here.
And frighten a few of us.
