As usual your analysis and your language skills are faulty. Please pay attention to what I said, "The mold cost is the same to make one fin or a thousand". This is true unless there is some degradation of the mold before then. Which you do not mention.
As to your analysis. The mold is a sunk cost meaning it was already paid for and cannot be recovered, consequently your allocations have no cash flow effect for Bob. I am not sure when (if ever) you took a managerial accounting course but the contribution margin approach has been taught since at least the early 1980s. If Bob is able to sell the fins for more than his variable costs (production costs, packaging, shipping, etc.) then he will have cash to cover his fixed costs. The objective is to maximize the total contribution margin. This assumes the rest of his costs are fixed period costs that do not vary with the number of fins sold.
As far as developing an exclusive product that depends on the margins and volume. He would be better off selling 2 fins each with a $200 contribution margin than 1 fin with a $300 contribution margin. I am not sure of what the elasticity of demand is for scuba fins, but Force Fins start in price where most other fins end. I am sure Scubapro would sell a Tactical Jet Fin for $500 if they thought they could get it.
I am sure that ScubaPro would do what you are saying, IF they could make it for $5 and sell it for $500.
As far as Force Fin's business model, I am not privy to their books, so I cannot provide any "real" data. Whether their business model is good or bad from your academic perspective, I have no idea. What does seem to come across from you, is you have limited knowledge of manufacturing a low volume molded product, using high $$ materials that does not fit the mass produced model you seem to want to use for comparison. Mold costs are not a one time expense (plus repairs and replacement) and must be amortized over their life - which means each fin produced must cover a portion of the initial/replacement cost.
I can tell you that Force Fins are made in 7 sizes (S, M, M-L, L, XL, XXL and XXXL) and each size requires a different mold. The designs are adjusted to maximize performance - smaller sizes tend to be shorter, narrower and thinner to provide the proper flex for the material being used. I believe that there are 8-10 models of Force Fins with fixed foot pockets and 4 that have adjustable pockets.
I can say for sure that in the case of the Flying Force Fin, in Tan Delta (#1) - I own pair number 120 (Bob signs and numbers all the higher end fins). So in the process of making 120 fins, he has probably created 7 molds at a cost of thousands of $$. So, if these fins are sold for $600 a pair, it does not seem that there is a tremendous profit margin - in fact, I doubt that there is much profit. These are manufactured because Bob wants to offer a product that will meet the needs/wants of the type of diver who is willing to pay for performance. My guess is that the Originals, Pros, Slim Fins, and SD-1s provide the vast majority of the income because of their higher volumes (and are therefore less expensive).
By the way - if you want to discuss credentials - we can have that discussion offline - but I assure you, mine are impeccable both academically and from a manufacturing/management standpoint.
