Pinta Home - Construction


current status

Hull Number: 0402-002

Hull Type: Brims
Hull Designer: Stefan Probst
Build Version: (not yet decided)
Overall Design: Stefan Probst
Overall Dimensions: 8'0" x 4'0"
Weight: Hull: (not yet known), Empty: (not yet known), max. Displacement: (?)
Manufacturer: HAPBY (Hanoi Private Boat Yards), a still purely virtual entity
Boat Yard: Kim Ma Thuong, Roof Terasse Dock
Construction Period: Starting middle of November 2004
Launch: Planned for February 2005
Builders: Anna-Ly Probst, Stefan Probst
Construction Type: Plywood, Framed
Construction Details: inside grade plywood:
bottom: sandwich of 7 mm (1/3") ply / GF / 3 mm (1/8") ply;
sides: 8 mm (1/3"); transoms, fore deck: 12 mm (1/2")
all plywood edges protected by logs
inside and outside 2 layers Epoxy; bottom 1 layer glass fibre
inside and outside 3 layers latex based paint
Design Objectives: Provide a boat that can carry the whole family (2 adults, 1 kid), plus picnic gear (i.e. about 220 kg / 500 lbs).
To be propelled by oars, electric drive (trolling motor), and maybe sail.
Improve and test adapted technology (protected ply, paint to epoxy adhesion).
Assess suitability of new boat yard premises (moved from Thai Ha to Kim Ma Thuong).
Provide test platform for small electric propulsion systems.
Provide test platform for modular construction: Modular superstructure, modular hull.
Provide dry dock for OSS Santa Maria (i.e. dry storage).
Have fun.
Notes: After the "Santa Maria", this is the second boat in our "exploration" series. Consequently, she is named "Pinta", the name of Christopher Columbus' second ship, when he discovered America.
31.07.07 - The End: We are closing our Kim Ma Thuong boat yard (i.e. we are moving).
Pinta has been in an half-finished status since quite some time. I could not decide whether to continue or to scrap her. The original purpose is still valid, but I recognized meanwhile that a 4' beam is not enough for useful modular construction, i.e. to assemble a long TIMS-like boat. The modules also get too big for "portable use" like the King Nuts.
To continue her would mean that she would only be used lone, or together with King Nuts, a bit like a single ended proa.
Also, it looks like there is meanwhile outdoor quality ply available, which means that it would be much easier to use that new material than to make sure that Pinta, with her interior grade ply, is really completely encapsulated in Epoxy.
Finally, to bring her down from the Roof Terasse Dock, to an unknown storage space (no major building in the next place ... for about 6 months probably), made the decision easy: Say goodby and leave her behind.
Her successor (Pinta II) will probably be a Bolger 8' Fast Brick, widened to 5'.
