Status 580 Mast support

I'm looking at a Status 580 but found rot in the form ply(?) under the mast support just forward of the swing keel. The rot extends forward until approximately halfway under the 'cabin' area. Just forward of the keel, the port and starboard tanks have holed, as well as the two tanks between the forward inspection ports.

I'm trying to determine if this rot is a deal breaker or worth persevering with, so question time.

1. I presume there needs to be structural support under the mast support, can I repair this 'rot' with another mast support, or is ply and epoxy/fibreglass the only way?

2. Do the tanks need to be sealed off from each other to maintain safety?

3. Is this a common problem? If so can I repair this with out cutting up the floor and using smaller strips of repair material through the inspection ports?

4. I presume the original damage occurred from leaking around the keel pivot bolt, what is the best method to prevent a reoccurrence?

Thanks in advance.

Re: Status 580 Mast support
From what construction I see in the photograph I would assume that the Status 580 would have been built in Sydney during the late 70s.

We completley redesigned the interior mould so that the mast step support ran thawtwise, and was part of the interior moulding, and no timber was used in its construction.

Of concern is the nature of the hole under the mast support, it appears that the laminate there is far too thin (should be at least 8mm thick,) as with good hull laminating practice the boat's shell should be double thickness there for at least 100mm in width for the full length of the keel.

If you can cut the small piece that protudes from the hole and burn it, then that will leave just the glass content, and if you cannot detect any woven roving residue then you must assume none was used in the hull construction. If that is so, then I would not go ahead with with the project, as your repair problems may be never ending. (usually if a laminate containing woven rovings is damaged it just splits and the remaining pieces remain attached).

1. Beware also that you can expect all the remaining timber used in the boat will have deteriorated .

2. You may be able to seal off the floatation tanks with pouring foam.

3. If you do go ahead with repairing this boat there may be no alternative to using timber again.

What ever you do , this will be a big job and it would be very important to thoroughly clean and abrade the surfaces that are to be repaired.

Good luck.

Re: Status 580 Mast support
Hi, I'm the owner of the Status and suggested Pete try this forum for some advice. Assuming Pete does not go ahead I'll be keeping the boat and looking for a repair that will work for light sailing around Canberra. I was thinking that with the ply removed, perhaps a fiberglass patch each side with some spaced reinforcement from deck to keel? I'd welcome any advice or ideas for the repair. Cheers Mike

Re: Status 580 Mast support
Pete and Mike.
A ring frame could be a quick and satisfactory way of solving the compression problem from the mast if you can get a fastening to the side of the hull or interior moulding, it would also take the strain off the bottom of the hull and elimenate the need for further timber work under the floor.

Rob, thanks for that - I appreciate the advice.
