3. Creating my first trimaran from a kayak...


Kayak: Pungo 140 (Wilderness Systems)  


Length = 14'       Max Beam = 28"       Weight = 55 lbs


Amas:  Length = 7'10", width & height = 6" avg, weight = 9 lbs ea.


Total weight rigged as trimaran = approx. 95 lbs


Observed top speed = 9 mph


My first homemade amas, under construction.


I made this rig so I could fiberglass both amas at once.


Test-fitting the amas, akas (crossbeams) and leeboards. I had made the rudder previously.


First test sail, using our 40 sq. ft. homemade lateen sail. Worked great!


The same rig in profile. Note also the homemade rudder.


Sailing test with our "small" sloop rig of about 32 sq. ft. OK, but not great.


They sure look much better painted!


With painted amas and our 52 sf. "sloop rig" - a lot quicker!



Big "sloop rig" worked well, but the 40 sq. ft lateen also worked great and was a lot less hassle.
