Many years ago we had a steering failure, cable pulled out on a different boat than we have now. Anyway, long story short, with the high wind and without a means to steer through the crab traps we pulled out that BoatUS card and dialed them up. It would have been $1200+ for the tow back to our slip were it now for that ~$100 per year fee. Put that together with two tows when we had a 17' bow-rider before that that had a few engine problems causing us to request a tow and we are still way ahead.
I guess its just about risk mitigation. If you are 100% certain of your systems, then you have mitigated the risk in your favor but sometimes the defecation has an impaction upon the oscillation device.
