Your market research should also include identifying your potential customers and size of the market. It wont be cheap to set up production of your tender and there are basically only two reasons why you can’t find competitors: A). either your competitors don’t believe there is a market for this product or B). they are wrong and there is a market. You have to hope for B), of course;-). And you have to hope they did not properly research the market…
But I would definitely try to identify who would buy a small tender in CF? Say it is a tender for a luxury yacht then yes, why not have a swank one in CF, as they are already spending a ton of money. But 2.5m is too small for them, right? So, who is left? Most often people who don’t have the budget will go down in size of boats, tenders, too I would think. And if they are out to save money, they won’t go for CF.
Not trying to kill your plan, just thinking out loud:-)
