We had a boat built by Stillwater in 2010. There were serious delays in its launch and when it was launched it was so badly ballasted that it didn't get off the slings and was immediately hoisted back onto the truck.
3 years down the line I have had to paint the cabin myself, couldn't afford a pro job,. lots of corrosion below the original paintwork.
Also at the same time I discovered.that the company had not completed the engine installation document for Vetus hence no engine warranty. Engine needed new mountings. Persistent water leak from skin tank bottom hose discovered to be the result of failure to put any sealant on the tank fitting thread.
One Year down the line I discovered that the agreed galvonic isolator had not been fitted, the company did fit this.
Poor fit of internal panelling around lounge windows. Fit of some cupboard doors poor.
Having said all this the boat is still floating!
