Just my 2 cents ..
I think it's a Glastron / Carlson CVX16 built in Anaheim California for the 1980 model year.
Shipped to Canada, sold, Carlson emblem cracked or fell off.
Owner couldn't find a original Carlson emblem or liked the Glastron emblem better ..So replaced with Glastron emblem.
Not sure why a dealer or importer would remove emblem .. Glastron and Glastron/Carlson were the same company.
Only way to tell ( for sure ) which year the boat is .. is by HIN.
Titles & reg. papers are often wrong for many different reasons.
There were a few splash's CVX hull's in Canada.
Easy to tell by stern, dash and HIN's.
