The Mangalui Ndulu was built by well travelled surfers for the sole purpose of sailing the wave rich coastal islands off Sumatra. Matt Cruden and Greg Spindler designed a comfortable vessel capable of doing those extra miles to give you a little bit more on your Sumatran Surf Voyage.

For over a year Matt and Greg lived in a small primitive village on the eastern side of Indonesia on the Island of Sulawesi. Working closely with the Bugis boat builders to bring together some Eastern and Western knowledge and create the 82 foot solid ironwood and teak wood motor sailor.

The Bugis men are well known sailors and pirates of Indonesian history. Their sailing vessels largely influenced by the Dutch trading vessels of previous centuries, during which the Dutch moved into the area to reap the benefits of the ‘spice islands trading’.

After the six-week mission of launching the MangaluiNdulu across the ribbon reef lying offshore (using many hands, block and tackle, tug boats and hundreds of 44 gallon drums), she set off for a two-month journey around Indonesia for her test run with a few mates. Arriving into Sumatran waters in late October 1996.

The Mangalui has been operating out of Padang in West Sumatra since then doing surf trips up and down the coast, from Panaitan Island In West Java up to the northern islands of Aceh (North Sumatra) We are now proud to say that we can enjoy the benefits of all our efforts in building the Mangalui and its operation with many friends from all parts of the world. Her reputation speaks for herself with our high percentage of return guest who come to enjoy her mellow, relaxed vibe, memorable times and taste the epic waves Sumatra has to offer.

From the turn of the century, Matt Cruden continued to run charters with his wife and children on board for quite a few years. These days with an ever-growing family Matt has taken on partners and shares the ‘Mango stoke’ with them and our experienced Captains.
