This are pretty standard hinges for all kind of furniture doors. Manufacturer is "BLUM", and they are sold worldwide. No need to buy at SVB for "marine" prices.
Try to identify all type numbers and signs, which are usually applied on the backside of the hinge and the baseplate to get the correct one to buy online or
try to google the nearest dealer which has them on stock and can give advice, take a sample of that hinge (including the baseplate of your hinge, which is missing on your photo), make a visit and select the right one. If you don't have luck with "Blum"-hinges, you will find other brands of hinges, which will fit too.
