Length:  15' 0"
Beam:      6' 2"
Deadrise:  4"
Hull depth at Midship:  28"
Hull weight:  No Clue
Displacement:  Even less of a clue
Maximum Power:  55 hp or so...

Length -    How did I decide on the length - you ask?  Very
simple:  Of the free wood I received, most of the boards were 16'
in length.  That left me enough to trim any uneven ends and to
allow for bending that would not break the wood.  Through all
this scientific data, I wound up at 15 feet.

Beam -        You might detect a pattern here.  Of the old growth
Heart Pine beams I had available for a frame, together with a 15   
degree angle for the sides of the boat, resulted in a beam a
little over six feet.  Again, here you have the height of scientific
nautical design at work.

Deadrise-    I don't know if I got the term right, but from the bottom
of the vee to the side of the boat rises 4 inches.  A flat bottom
would have been easier to build but I don't like the way flat bottom
boats handle at speed.  They seem to lack directional stability.  
Many builders add strips to the bottom of the boat to compensate
for this.  I added a slight - but what I hope to be effective - vee.

Hull Depth -  Kinda eyeballed this one.  I looked at other designs
and decided how much deeper I wanted mine.  I'm trying to avoid
being swamped at even very rough conditions.

Hull Weight - I'll weigh it when I'm done.  My gut feeling is that it
will be a heavy boat.  When I flipped the hull, it certainly felt
heavy.   The heavy weight, for this size boat, will decrease the top
speed.  But I'm not building a speed demon.  The higher weight
should increase its stability while at rest.

Displacement -  If a gallon of watter weighs 8.3 lbs or so,  I
calculate the boat will displace somewhere in the neighborhood
of:  HA!  I really had you going!  I have no clue and it has been
way too many years since I used my college calculus to
figure it out.  Plus, I don't really care so long as it displaces
water and does not leak it.

Power:        For power, I settled on 55 hp. This decision was
made because I only wanted a 2 cylinder motor to keep weight
down.  I bought an 85 hp 3 cylinder off Ebay.  BUT, the Sea
Sprite donor boat I bought (also off Ebay) wound up being too
nice to part out so I combined the two and sold it.  The Sea
Sprite was christened "Skippy" by the proud new owners who
happen to have a slip down the dock from me.

The 55hp powers the boat nicely - a comfortable 22 mph cruise
in choppy water and a 12 mph plane.   Top speed is 28 mph with
the current prop but the water had best be smooth at that speed.
It is very economical to operate.  But best of all are the looks I get.
