Free calculators for boat builders
Small calculators for the questions that come up in every build: how much epoxy, how many sheets, how fast will she go, and what to call her. Imperial and metric, free, no account. Each page explains how the number is worked out, so you can check it against your own plans.
Epoxy calculator
How much epoxy to buy: area and coats in, liters, gallons and kit sizes out.
Plywood sheet calculator
How many sheets of plywood your panels need, with scarf joints for the long ones.
Hull speed calculator
The theoretical top speed of a displacement hull from its waterline length.
Boat name generator
Names worth painting on a transom, from a hand-picked word list.
For how long a boat really takes, the hours are in the build logs: see the numbers, worked out from every log on the site.
