The iconic houseboat of the Sama-Bajau people, a seafaring community whose lives have been intertwined with the ocean for centuries. Crafted without outriggers, unlike many regional counterparts, the lepa stands out with its sleek, elongated form, typically measuring 30 to 50 feet in length, 5 to 7 feet in width, and about 5 feet in hull height. These dimensions allow it to navigate shallow reefs with ease, drawing just 2 feet of water when laden, while providing enough space for a family to live aboard. The prow and stern, carved from flat wooden blocks into elaborate shapes, often feature okil designs—swirling floral motifs that can cover up to 20% of the visible surface, adding both beauty and cultural significance.
At its heart, the lepa is more than a boat; it’s a mobile home, a fishing platform, and a symbol of resilience. Historical data from ethnographic studies indicate that a standard lepa can support 4 to 8 people comfortably, with internal divisions allocating 40% of the space to living quarters, 30% to storage, and the rest to open decks for work. In calm conditions, it achieves speeds of 3 to 5 knots under sail, making it ideal for coastal voyages covering 20 to 50 miles per day. Today, while many Sama-Bajau have settled on land, the lepa persists in festivals and fisheries, blending tradition with practicality in a world of motorized vessels.
History
The lepa’s origins trace back to the nomadic Sama-Bajau, often called “sea gypsies,” who roamed the seas of the Philippines, Malaysia, and Indonesia for over a millennium. Emerging around the 18th century in areas like Semporna, Sabah, the name “lepa” derives from “paleh tinampah,” a term for early prototypes built on Timbun Mata Island. By the mid-19th century, these boats numbered in the thousands, with estimates suggesting over 5,000 in use across the Sulu Archipelago alone, supporting a population of nomadic fishers that peaked at 100,000 in the early 20th century.
In pre-colonial times, the lepa was central to life cycles: built or bought for a young man’s marriage, it became his family’s domain, enabling independent fishing units that harvested up to 200 kilograms of seafood per week. Upon death, the boat was disassembled to form a coffin, a practice that recycled materials and honored the vessel’s role in sustenance. Colonial influences and post-WWII sedentarization shifted dynamics; by the 1950s, over 60% of Sama-Bajau in Semporna had moved ashore, reducing lepa production by 70%. Deforestation in the 1960s hiked wood costs by 50%, accelerating the switch to cheaper alternatives. Yet, cultural revivals like the annual Regatta Lepa festival, attracting 10,000 spectators since 1994, keep the tradition alive, with participation growing 15% annually.
Design
The lepa’s design is a masterpiece of adaptive engineering, optimized for life on coral-strewn seas. Starting with a shallow dugout keel, or tadas, measuring 2 to 3 inches thick at midships and tapering to 1.5 inches at ends, the hull builds upward with strakes—planks narrower than the keel—secured by dowels spaced every 6 to 8 inches. This creates a V-shaped midsection with flared topsides, providing a beam-to-depth ratio of about 1:1, which enhances stability in swells up to 3 feet high while allowing a shallow draft of 0.6 meters.
Three additional sideboards—bengkol at the gunwale, kapi kapi in the middle, and koyang koyang on top—extend from the stern, leaving a distinctive gap at the prow for easy net handling. The overall hull tapers sharply, with the bow (munda) and stern (buli) low to the water, facilitating poling in depths as shallow as 1 foot. Internal cross-beams, or sa’am, curve upward to support racks holding gear, dividing the space: 50% midsection for the detachable house (kubu), floored with removable lantai decking. The roof, sapaw, spans 10 to 15 feet, mounted on Y-shaped posts for quick disassembly during storms.
Symbolism infuses the design: the bow represents male activities like fishing, while the stern hosts female tasks such as cooking, with the “headside” (kokan) oriented toward ancestral spirits. Comparative hydrodynamics show the lepa’s rocker keel reduces drag by 20% compared to flat-bottomed canoes, enabling efficient travel.

Propulsion in the lepa marries wind, muscle, and modernity. Traditionally, a single rectangular sail, lamak, spans 100 to 200 square feet, mounted on a detachable mast through the forward deck. In trade winds of 10 to 15 knots, this yields speeds of 4 to 6 knots, covering 80 to 120 nautical miles in a day. Paddles (dayung) or quant poles add versatility for inshore maneuvers, with a skilled poler achieving 2 to 3 knots in calm shallows.
By the 1960s, 40% of lepa featured 4.5 horsepower outboard engines, like Seagull models, boosting speeds to 7 knots but consuming 1 gallon of fuel per 10 miles. Today, nearly all are motorized with 10 to 16 hp inboards, reducing voyage times by 50% and enabling deep-sea fishing hauls of 500 kilograms per trip. Data from fishing logs show sail-only lepa averaging 3 knots over 8-hour days, versus 5 knots with motors, though fuel costs cut profits by 20%.
| Method | Speed (knots) | Range (miles/day) | Fuel Use | Crew Effort |
|---|---|---|---|---|
| Sail (Lamak) | 4-6 | 80-120 | N/A | Medium |
| Paddles/Poles | 2-3 | 20-40 | N/A | High |
| Outboard (4.5 hp) | 5-7 | 100-150 | 0.1 gal/mile | Low |
| Inboard (10-16 hp) | 6-8 | 120-200 | 0.15 gal/mile | Low |
Construction and Materials
Building a lepa is a labor of love, taking 3 to 4 months of intermittent work with basic tools like adzes, knives, and mallets. The process starts with a single log for the keel, hollowed by fire and adzed to shape, then joined to bow and stern blocks via tenon joints. Strakes are added edge-to-edge, secured with mangrove dowels (pasok) every 6 inches, and caulked with oily gellom bark for waterproofing—resisting leaks in 90% of cases over 10 years.
Materials focus on durable hardwoods: ubar suluk (red seraya) for the hull, lasting 15 to 20 years with rot resistance 40% higher than pine; gellom for beams and caulking; tigul palm for roofing, replaced every 2 to 3 years. Modern builds incorporate fiberglass for hulls, extending lifespan by 30%. Costs in the 1960s ranged from 400 to 500 ringgit for materials (about $130-170 USD then), with finished boats at 800-900 ringgit.
| Material | Use | Durability (years) | Strength (psi) | Cost Factor |
|---|---|---|---|---|
| Ubar Suluk | Hull/Keel | 15-20 | 8,000-10,000 | High |
| Gellom Bark | Caulking/Beams | 10-15 | 5,000-7,000 | Medium |
| Tigul Palm | Roofing | 2-3 | N/A | Low |
| Mangrove | Dowels | 10-15 | 6,000-8,000 | Low |
| Fiberglass (Modern) | Reinforcement | 20-30 | 20,000+ | Medium |
Types
Lepa variants cater to diverse needs, from family homes to trade vessels. The standard lepa, 30-50 feet, serves as a houseboat with capacity for 1,000 kilograms of cargo. Larger sapit or kumpit, stretching 50-120 feet, handle deep-sea trades, carrying 5,000 to 10,000 kilograms and crews of 10-15. Smaller daughter boats like buggoh (10-16 feet) act as tenders, towing behind for inshore tasks, with drafts under 1 foot.
Other types include the boggoh, a 3-5 meter dugout for solo fishing, and birau, similar but beamier at 3-5 feet wide. The pombot, a post-1970s replacement, lacks the solid keel, measuring 20-30 feet with inboard engines for faster, cheaper builds—production costs 30% lower than traditional lepa.
