Almost all boats are constructed on a production basis, as this is the most efficient means of production. There's only one set of molds and many boats being built from the mold, reducing the cost of tooling per boat. Normally, there are a limited number of options to make assembly line production more efficient in terms of cost.
Leaving the ranks of production boats, there are several types of custom construction. There are many boats built with a limited budget, which is normally by amateurs. If you don't want to build the boat yourself, the next level available is what sailors call "semi custom" boats.
These semi customs are normally built by small or mid sized shops out of one set of molds so the hull and decks could end up being identical. The builders will however, allow the owner to pick out the interior and other options.
The true custom built boat, or one of a kind boat, is specifically designed and built from scratch for a single customer with an unlimited budget. A true custom boat is a one on one project, and can get very expensive before you know it.
Before you decide to go out and buy a custom boat, you should give the used market another look. Those who have built custom or even semi custom boats in the past do put them on the market for sale at
some point or another.
This is a much less expensive way to go, simply because you won't be paying a professional to design the boat from scratch. You can find used boats that offer one of kind features and options, all you have to do is look aroun.
