Fastening a Phinisi: Wooden Pegs, Bolts and the Strength of a Bugis Hull

By Tana Beru Boat Builder — Build Desk · August 19, 2026

A Bugis phinisi is fastened peg-first: long wooden dowels are driven through the planking to draw the seams tight, and galvanised steel bolts and drift fasteners are added where load demands. This combination makes the hull strong, fair and repairable plank by plank.

Pegs First

Before any steel goes in, long wooden dowels lock plank to plank, pulling the seams tight. This peg fastening is central to how a Bugis hull is assembled and is one reason the boats have crossed oceans for centuries.

Bolts Where Load Demands

Steel drift bolts and galvanised fasteners are added at the keel, frames and high-load areas. The hull is not either-or; it is wood and steel used each where it belongs, in the traditional order.

Strong, Fair and Repairable

Peg-first fastening gives a fair hull and, crucially, one that can be repaired plank by plank far from any yard — a real advantage for a boat working remote waters. See the full method in how a phinisi is built.
