The fish-tank is a 1986 Rybo Runner.

Length: 30'    Beam: 10'    Propulsion: 2x mercury optimax 225 hp

    dry weight: unknown  fuel capacity: 350 gal     

top speed: 35 knots    cruising speed: 27 knots

The vessel was designed by fisher marine tech, (fisher is known for “body by fisher” on most American made cars).  The boat was finished in the rybovich boat yard of West Palm Beach, which was under fisher’s ownership at that time.

This was the first sport vessel to utilize a “stepped” hull, a design that was originally used for seaplanes.  Now a very popular design element for performance sport boats, This design reduces drag and allows the boat to “plane” faster and cruise more efficiently.

The photos below show the second step's "air box", a design that was later abandoned, in favor of open slot design.  The holes at the water line allow air to vent through slot on the aft side of the step, thus breaking surface adhesion with the water.

 

I found the boat listed at national liquidators in fort Lauderdale.  as a bank repossession, she was in need of some t.l.c., but sound.  after being outbid, (the auction winner defaulted on the deal), I was able to acquire the boat for $21k (pretax).  since ownership, I had to replace one powerhead, due to a water intrusion into the oil reservoir.  unfortunately, while in the yard, some f*cking thieves had stolen the lower units, props, and some other miscellaneous items...an unforeseen event that ended up costing me an additional $17k on the investment.

 

 notwithstanding, after the replacement parts, some detailing, and the addition of some "body art",  i now have a mechanically sound and solid fishing platform for under $40k.

Finally back home and ready to fish:

The fish-tank’s “trunk cabin” is unique…no others were built. All the other Fisher Marine Tech/Rybo Runners have center-consoles that have a head inside

There were approximately 80 Rybo Runners ever constructed.

Since the 1980’s the Rybo runner molds have been acquired by several boat builders, and there are a number of “one-off” designs inexistence. Currently “Typhoon Marine” is building boats based on the Rybo runner hull.
