Re: placement of skid fin

[bh]

Traditionally they were placed about 4′ fwd of the transom on the centre line. As racers began to raise their motors, some found turbulence from the fin cauised cavitation , so they moved it about a foot off centre to the left, as in NA we always turn left. Problem for cottage/river racers is the boat will not turn to the right very well , and turbulence will affect the prop in right turns.
For hobby use, and since u are not concerned with every last mph , I would attach one or two ‘skid rails’ , ie pieces of hardwood, maybe 2"x 2" or so, along the bottom that would help steering some and make it much easier to trailer and beach.
Your choice. PS; -that fin may be a bit big ?
