Premise:I have 85 gold.
I would like to spend it on hirelings and capital so I make a profit.
I would like to do this by catching and selling fish.
Expenses:A somewhat seaworthy vessel is the Dugout Canoe. It costs 20 gold, and holds 4 people, according to Stormwrack.
So, I have 4 fishermen. This is unskilled labour, and an untrained hireling costs 1 sp/day, according to the DMG.
As of now, I must make at least 4 sp/day to cover my day to day expenses.
They each need a fishing rod. The rod itself is easy: a quarterstaff, which has no cost. Having no RAW cost for fishing tackle, I will assume that 25 feet of Silk Rope equivalent will suffice for each fisherman, each day, which costs 5 gp for each fisherman.
My day to day expenses are now 5.4 gp.
Now, they need fishing hooks. The SRD lists a fishing hook as costing 1 sp. I am assuming they each use 2/day.
My day to day expenses are now 6.2 gp.
We will assume that the boat becomes unusable after 20 days, so we accrue an equipment depreciation expense of 1 gp/day.
My day to day expenses are now 7.2 gp.
We will round it to 10 gp to account for unforeseen expenses.
I will hire a clerk to manage the business in my absence. I will hire an old, VERY trustworthy friend from the legion (my character served in the Legion of Doom) and give him a 20% cut of net profits.
Profits:This source says that a single man can expect to pull in ~100 pounds of fish per day using the handline method:
http://www.galapagos.org/wp-content/uploads/2012/04/biodiv8-white-fish-fishery.pdfDue to technological innovations and skill, I feel safe in cutting the catch by half, but I suspect that the actual number would be higher. However, I have no evidence to prove this. So, my fishermen catch ~50 pounds of fish per fisherman per fishing day.
Let’s assume that all they catch are Sardines, a mid-cost fish, by the Arms and Equipment Guide’s standards, at 4 gp/pound.
Let’s assume that I sell to a middleman, who resells the fish at a 100% markup, meaning that I sell my fish for 2 gp/pound.
I have four fishermen, each pulling in ~50 pounds of fish, for a total of ~200 pounds of fish a day. This is resold for ~400 gp, each day.
