Hey , -- Just a few comments from the builder of the only Water Van in the
The boat is a joy to operate above 10 Knots. Below 10 knots, because of the
nose heavy design, it tends to wander, and a 2.5 to 3' wave, square on, will
ship some water over the bow. Above 10, through 16 knots the wandering goes
away, the bow comes up nicely, and she runs very dry, even in 3' to 4' chop
and swells. At 18 knots she starts to plane and by 20 knots the Water Van
levels out and feels like she's riding on a cushion In fairly calm water,
with the Suzuki DF 115, she will easily cruise at 25 knots.
The forefoot / box keel is almost 3' wide for most of its length, and runs
6" below the main hull. There are 2 mini keels at the outboard edges of the
main hull, about 2" wide and 3" down. It appears that turbulated water and
air is trapped between the box keel and the mini outboard keels; effectively
creating a slippery foam cushion at the 10 to 18 knot range.

Thanks for posting the text. This is perfect. What issue was this
in? (I'm sure I have it, my collection goes back to 1990 - the only
problem is that I have them archived 3 deep in a floor level
In looking at Fastbrick, it has the forefoot but not the box keel
per Watervan, Clam Skiff and the tugs.
The design I've been playing with is a loose adaptation of Jim
Betts' Gypsy's Poke (which he never took beyond the cartoon stage).
A forefoot and perhaps a shallow box keel might go well with this
