This is not to be viewed as a complaint or negative comment. I think of it as a TugNut service bulletin based on my personal experience. My issue may be a one and done issue or there may be other Cutwaters or Tugs that have this issue. When I find a discrepancy in QC it is not to say that the product is poorly built. It is to notify owners and the product customer service representatives of an issue I found and repaired. I hope this post and other maintenance post are viewed as me informing other owners of my findings and experiences. I also hope that my posts are viewed as my opinion when I say in my opinion.

Having owned the boat for 4 years we have never had a leak at the "coach roof". This year, actually last month when I loaded the boat on the trailer I noticed a brown rusty looking water leaking out under the "coach roof". The boat was sitting on the trailer bow down. The boat normally floats bow slightly elevated. The brown water ran into the roof side drains and then into the cockpit. I cleaned up the mess and trailed to our Kentucky destination. We experienced a heavy rain over night when we were in Kentucky and this was our chance to see if our new cockpit enclosure kept the rain out. My wife was checking for canvas leaks and kept saying the only leak is from the coach roof. I was worried that the canvas shop drilled a hole somewhere but I could not find any discrepancies. I removed the teak veneer ceiling under the coach roof to see if I could see where the leak was. The leak was easily found. The 4 1/4 -20 screws that were fastening the mask to the roof had drips of water coming off of them. My thought was the screws came loose and the mast moved and broke the sealant seal. I inspected the tightness of the screw/nut and found them to be very tight. I inspected the mast and found it was tight and no evidence of it moving. I knew that I had to seal the screws to fix the leak.

Removal of the mast. There are 4 screws 1/4-20 with lock nuts and small 304 ss washers.Two of the nuts are difficult to get to but achievable. There are two #12 self tapping screws that hold the mast too. I removed all 4 ,1/4 -20 screws and left the #12 screws in my thought was I will need to break the sealant seal loose when all screw are removed. When I removed the 2 #12 screws the mast started falling.

Findings:

There was no sealant used to install the mast. No trace of sealant. There is wood used in the cunstruction of the roof for reinforcement it was saturated with water and this is where the brown water was coming from. I feel the integrity of the coach roof is compromised. I was able to dry the wood to the best of my ability at the dock. ( we are on a trip ) I used my wife's hair drier. I am assuming this has been leaking for 4 years so there is possible damage to the exposed wood that is not resin sealed. I will deal with this when we are done cruising and remove the coach roof to make integrity repairs.

Reason for thread. Make a quick inspection of the mast and see if there is any evidence of sealant under the mast base. If not I would inspect as I did. Positive of the temporary repair. I have repaired the leak and the couch roof area is completely dry. I have tested it several times with the hose test. water pressure from a hose aimed directly at mast base. .

Excellent write-up! Yours is a model for future Tugnut Service Bulletins, and enrich all those who read them!
 
Brian,

Great post and thank you for the update. This is the exact reason for this forum which is for us to learn and hopefully for others down the road. Thank you for posting and I will be sure to forward it off to the plant manager to have a look at the boats being built in the factory.

Thanks again,
