24SE engine compartment volume
 

What is the cubic feet volume of the engine bay on a 24ft Pantera -Im planning on fitting an auto fire extinguiher and would like to know if 100 cu ft is enough?

I think you can do L X W X H

I'm just thinking about my engine compartment (seeing as that's where I've been spending a lot of time lately - motors out and I'm cleaning it up and re-rigging).
Gotta figure:
Beam - 6'6" to 7'
Length - 4' to 4'6"
Depth at keel - max 4'

I'm thinking max 126 CF - and that isn't taking into consideration for the 24 degree deadrise.

I think your 100 CF is probably about dead-on.
Mind you, this is just a quick calculation off memory and approximation, but I think you'd be pretty good with the 100.

I was calculating and typing while you posted Tom.:D

this is something you could go over kill on and feel good about it.
It would be an easy sell to the wife:evilb:

You're right, it would be easy to go over-kill on this one.
But, if budget is an issue (as it would be in my case), I would imagine these are already rated at an "over-kill" rating.
I'd spend the additional money elsewhere - unless it would look cooler:D
But, that's just me.

The motor is probably about 3x3x3 so there goes another 27ft^3

Does anyone else think that blocking off the rest of the boat would be a good idea (just in case)?

You're right.
I wasn't even taking the motor, transom assy, batteries, etc... into account.
Blocking off the area between the bilge, and under the cockpit/down the gunwales raises another good point.
Before this turns into over-analyzing this like what would happen in a GD thread, I'll just say I'd feel comfortable with the 100CF without blocking off anything.

thanks, cost here is £239 for a 100cu ft Seafire - Fireboy even more!

Need to get it for next weekend so I dont recon its going to be practical.
