Enclosed is a step-by-step walk thru to install a wakeboard rack to a 2009 bayliner 175 without a wakeboard tower. My objective was to install a wake board rack that met the following criteria:
1. Was a robust system and could handle the various loads of the boat (not a wimpy design).
2. Could support 2x wakeboards.
3. Would not interfere with the Bimini (in deployed and/or stowed position).
4. Would not impede boarding/deboarding from the dock.
5. Would not interfere with docking the boat (cleat line obstruction, fender placement...).
6. Easy access to board.
7. Would not obstruct drivers view.
8. Functional and clean aesthetics.
9. Quick disconnect feature (no tools req'd would be nice).
I've looked at a few non-tower wake board systems and they are either too expensive or did not meet one or more of the criteria listed above. I bought, from e-bay a wake board rack at $120 sold by e-bay member "lipboating" and seen here:

the wakeboard rack, from e-bay

closer view, seems like a nice item, aluminum made. The features I was looking for was the ability to attach to a 7/8 inch rod and fully adjustable mounting angles

bimini deployed on boat, the bimini brackets are 7/8.

attach rack bracket to Bimini aft vertical bracket

quick check of rack

Couple of issues:
1. wake board is too far back, would impede entry/exit of boat
2. aft bracket is not all that strong, worry about failure of bimini

bracket as clamped to bimini rod

move board to middle bimini bracket

seems better. Can not exit/enter boat with wake board attached except:
1. seems board is too high
2. The bimini support rod system may not be able to support the rack and board
I'll need to fabricate my own 7/8 rod and attach to the boat about this location

stainless steel rod at 6 foot in length, $40 from marine west

secure base with stainless steel wood screw right into the boat floor, thru carpet

attach rack

add board

side view
Observations:
The upper bracket seems to be taking too much of the load. Seems to be carrying the moment as a short couple. I'll need to remove the upper bracket and replace with a aluminum guard

bimini stowed, no issues

bimini down, no issues
Review, observations and lessons learned:
1. The 175 does not allow wake board storage in ski locker
2. The final installed rod and attach system is very robust. I can pull my full weight on the rack without rack/rod deflection.
3. Little loss in visibility.
4. No entry/exit issues
5. Although I have not tried out the system, that review will need to occur spring/summer, 2010.
Enjoy,
Keithm

Looks pretty good. The only issue I can see is in use when you approach docks and want to tie up with other boats. That would be something to be careful about.

What did your total cost and hours come out to?

Looks like a fun project.... Very Happy

May I ask what stops the thing spinning 360 when under way?

I gave quite abit of thought about the various translations loads (side to side, fore-aft, and up-down) and rotations (pitch, roll, and yaw) the brackect/pole would need to transfer to the boat. The yaw moment is the weakest of all the load environmnets. To resist "spinning" I drilled 2x small pilot holes in the CRES 7/8 support tube. The set screws of the base bracket will rest in these pilot holes. I have not field tested the function of the rack, but it will support my weight. If it spins I can add additional anti-rotational supports easily.
