Just a note to highlight how service should be carried out,..I fitted Smart tabs some time ago,they are now out of warranty. I noticed one of the rams had stopped working; (no resistance to upward pressure) on the Colonsay trip. Dropped Nauticus a note, explained the fault,.. they didn't ask where I bought them, or for a reciept, just that they were sorry I had a fault.
Within the week a apology and two new rams F.O.C from the states...great response...
Smart tabs are a great choice for a RIB.
