Al, question about my surveryor's write up..

[DLL]

Hi Al,
First, let me say my Surveyor, who I have used twice and will use again next week wrote me
up on a 1987 Tollycraft CPMY. Twin 3208TAs with appropriate exhausts.

Just aft of the Shower in the Aft Cabin, IF you raise the fake floor in the closet, you can see the Stbd engine's exhaust "pipe" going through a hole in the Bulkhead. It does not touch anywhere. The bulkhead is ... uh ... 5/8" marine plywood. The diameter of this hole is such that the exhaust is about 2 inches from the wood, all the way around the pipe. The exhaust pipe is typical diesel I would guess.

The write up said I lacked support between the bulkhead and the exhaust pipe. I called Gordon, who worked as the Purchasing Contractor for Tollycraft and I think he bought all the spare parts. If he does not know the answer, he will call another former employee and find out for you. He is a SUPER GOOD SOURCE.

He said there was never anything between the exhaust and the bulkhead. If a person ....
attached the exhaust pipe in any way to the bulkhead, his thoughts were it would pass vibrations thru the bulkhead, creating problems. That is a rough paraphrase.

Having been a Residential Real Estate Appraiser for almost 20 years, I try very hard to be nice to the person valuing my home, boat, etc. BUT I would like to explain what Gordon said to the Surveyor. He can write me up again, if he wants, but I will get Gordon to write a note explaining all this to the Insurance people. I guess I could print Gordon's email and hand it to our surveyor. He is a good surveyor and pretty nice guy. This will be the third time I have paid out of my pocket to use him. He is THOROUGH.

Have you ran across this particular situation yourself? On another boat or in an example of some kind?

Thanks Al.

If the vessel specs. out this way by the builder. You should be fine. Double clamps at all exaust ports, is the ABYC standard. Have you or any of the other owners of this vessel, changed the exaust stucture in any way?

Not to my knowledge. He said if the exhaust were touching the bulkhead we would get vibrations, etc. if I remember correctly.

What I did was get the foam stuff you put around your pipes at Lowes...split it and forced the open part of the foam down on the wood. It has the effect of cushioning the pipe if it moved, but it does not actually touch the exhaust pipe.

We shall see...he will be at the boat in a week.

I just read your reply again Al, this place on my boat is just a hole in the plywood. You can call the plywood a bulkhead, as in nautical terms, but it is still just plywood. If the hole is a foot across, the exhaust pipe is about 9 inches or so.

There are no clamps in this area. The exhaust pipe merely passes through the bulkhead as it goes towards the stern. No clamps anywhere. I can email you a picture if you want. Just think of a hole in the bulkhead and the pipe passing through it. It does not touch anywhere. That is the way Tollycraft designed it.

I can ask Gordon if he has any "specs" on it.
He might.

Thanks again, Dave

That is the way it was designed to be, Pete Slawek, AMS

I dont see where theres a problem. Did the surveyor tell you why he has a problem with this? Was there any information given in reguards to a standard that tells otherwise? Please get back to us.
