So how does one go about testing bottom changes before making them permanent?

For example, lets say I want to bond a temporary strake to the bottom for water testing? What materials are used?

We make them out of white oak and screw them to the bottom test move them around till we are happy them bond them in .

First time I saw this done was around 2002 when I was at the Sunsation factory checking out the first 288 MCOB and the buck for what would become the first (and only of that hull design) Innovator. Wayne was under a boat with sections of strake make out of wood screwing them into the bottom. I thought, "that's crazy man!" Lol!

The ole carlson boys in the texas days used to use bondo.. prob a polyester filler like dolphin glaze. Just for lake testing. You will prob need a second set of special trailer bunks at the ramp for that program. And a weekday off .
