TG,
If you would like to look at a boat that you can use for MANY purposes, take a look at a Concept. I am not saying they are the best for offshore but, they are a great boat and they do NOT have a balsa cored hull. That is what I am running now and I personally love the boat. They can be found at
www.conceptboats.com
Hope Trayder doesn't boot me off for this.
