Styrofoam everywhere!

Well i have started to clean out my new purchase (MacGregor 25) and as i have started to get into some of the holds, I find large quantities of chopped up Styrofoam. Asking my ex-navy friends, they say it is to help with buoyancy. I think that the displacement and buoyancy of the boat will not be helped with Styrofoam inside the hull, unless it is to fill compartments so nobody fills them with heavy stuff.

Overall question, why is it there and can I take it out???

Thanks

Scott

It's there in case you fill with water.

Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did. So throw off your bowlines. Sail away from safe harbor. Catch the trade winds in your sails. Explore, Dream, Discover.

Re: Styrofoam everywhere!

You can take it out but if you get holed your boat will sink. Since that foam is open cell it sometimes gets saturated with water. If that is the case you may as well remove it.

Most boats don't have foam. It was a selling feature for the Macs.

I sail.

I believe he means punching a serious hole in your boat, taking water fast. The styrofoam means you still have displacement. Without it, you will sink. Granted, your basically sunk either way ... Just not on the bottom perhaps

Re: Styrofoam everywhere!

If its chopped up it will just float out of the holds, so its not going to keep you afloat.
Clean it out & if you want flotation in those spaces get some spray in flotation foam.

Re: Styrofoam everywhere!

There is a MacGregor forum that is very, very active, and filled with knowledgeable people. Before you start moving the foam flotation around, I would talk to them. It's macgregorsailors.com. They helped us alot when we had a Mac.

Re: Styrofoam everywhere!

Hi Scott
I too have a mac 25, and yes the Styrofoam is for flotation. As was said just in case you get holed. In my boat I have a few good sized blocks under the cockpit area and under the V berth its almost full. If you do get holed at least you wont sink, the boat will float to some degree.
I also belong to the Macgregor.com board and they are a mine of info. Check them out. A great bunch of like minded sailors.
