It doesn't sound natural at all. I'm guessing here as there's not much context.
I think it's a description of a yacht, or similar vessel. The white tip line could be a reference to the many lines painted on the hull, like the plimsoll line for example, but I think in this case it's more decorative. Ambry I think is a misspelling of amber, and refers to the colour of the varnish (lacquer) painted on the line. 'Wale' I think is a misspelling of whale, which is inkeeping with the copper fittings, as in 'fixtures and fittings'
The online dictionary defines 'ambry' as
1. (Christianity / Ecclesiastical Terms) a recessed cupboard in the wall of a church near the altar, used to store sacred vessels, etc.
2. Obsolete a small cupboard or other storage space
which given the limited context does not seem appropriate.
