The grocery store at Trellis is well stocked if you need to top up your provisions. Restaurant options in Trellis are still limited but the market restaurant has expanded a bit - you can get burgers, roti,, or ribs there. It is also an option for take out if you want to eat on board without needing to cook. There is also a bar with burgers down the beach and Aragorns shop is also open.The folks who collect the Trellis mooring fee come around with ice as well.
You can get water at Marina Cay and their temporary tent restaurant is pleasant with a decent menu.
