After seeing Nick's creation and all of the variations at MalibuCrew I thought I would join the club. Since my 07 did not come with the extra surf tabs, I purchased some Lenco 15060-001 (the HD ones), some 1/2" polycarbonate, hinges (ended up using 12 ga trim tabs), a switch, and a bunch of SS bolts and screws.
The tabs are 12.5", taper to 11.5" and are 22" long. They are laminated 1" thick and weigh about 10 lbs each. Since I have the old style swim deck, I designed the retract position to be right at the deck versus going under it. It extends to 112* measuring from the stern (22* longitudinal). It almost took a lot longer to fiddle with setting the position than to actually install it. For now the tabs are manual. When I figure out how to build a logic controller I will make it automatic.
Laminating and then run through the router to round the edges. I added some color to the glue, but the pressure was a bit too much in a few spots. If I get real keen after I know this works, I will add a matching wrap or gel-coat it.
