I can’t give you specifics on this but I have a 2006 1700 Fisherman which I believe is one step up in size and hull. I believe both are comparable to the rebel/impact line but you could just call a Lund dealer or walk in and ask. I really like my boat but these lower end Lunds are notoriously underpowered. Mine has a 90HP Johnson 4 stroke and is rated for a 115. I wish it had the 115.
As far as big water, I think you’ll be OK on that size lake so long as you have the full windshield model. I’d be careful on bodies like ML or Red Lake but I think that goes for almost any boat in windy conditions.
There are a few other forums if you google that boat that have a bit of info but it is limited.
