The link above in Chromers post is me being towed into Roche Harbor after my trusty 1994 Yamaha 70 2 stroke lost a bearing. Ouch. I used my 3 hp dinghy motor to get us into a safe and comfortable spot -- I suppose we could have used the little motor to get back, but very slowly. Plus, I didn't want to chance the currents in the pass with such little power.
On the same trip, before this, just as we got to our rental house on San Juan Island I had a different problem.
As the link here illustrates, you DO NOT want to back a boat down an sloped driveway made of gravel and mud in the rain. Nothing like sliding sideways down a driveway. Since I have the BoatUS trailer add-on for $10 (?) they sent out a tow truck and we were on our way. We almost needed them again to tow the boat up the ramp at Roche since the 'ramp' is not much more than a beach with some broken asphalt. Yes, I tow with a minivan -- but the trailer endorsement is a whole lot cheaper than a 4 x 4. And, in So Cal I've never needed a truck to tow.
I've had good experiences with Vessel Assist/ Boat US in the past. They are a great convenience -- but they do not replace common sense and proper equipment.
When I was younger on my father's sail boat we had a pin hole leak in his deisel auxiliary fuel line. This was before the days of Vessel Assist. Needless to say we spent the night becalmed -- perfectly safely -- off Palos Verdes where its too deep to anchor. It would have been a great convenience to have been towed in to Marina Del Rey.
Years later, on my own boat, after enjoying a great summer weekend in Avalon, we headed over to the fuel dock to gas up with the intention of making an evening passage home. Did you know that fuel docks close at 5:00 pm? Well I didn't... I was young and stupid. That said, we called Vessel Assist Avalon who was more than happy to sell us 25 gallons at their cost. Clearly we could have waited until the am -- but we had already sent half our party home on the ferry -- so again, the convenience of vessel assist made the weekend run smoothly.
Now, with kids and other responsibilities which make spending an unplanned night floating REALLY inconvenient I have found Vessel Assist to be well worth the money. It is really the least expensive part of my boating budget -- and when I need them (even if just for convenience) I am delighted to be able to use their services.
