I am curious though, on our boat we carry 20 gallons of diesel and I can motor for about 24 hours at cruising speeds, why the need for two fuel stops in a 6 hour motor? That sounded a bit odd to me.
The short answer is that I was unable to fill up at the first stop as they no longer sell gas.
In the interest of sharing, here's the long story in case anyone wants to learn from my mistakes. Maybe I should change my screen name to "still learning"
Background: we have a 15hp 2 stroke ob and two 25L gas cans.
I wasn't able to get off work in time on Friday to fill up so we had to leave with one empty tank and one only 2/3 full (we had to leave before the Deep Cove pumps were open to make 2nd narrows at slack). That was enough to get us to Mosquito Creek.
I only filled the empty tank and didn't top up the one we'd been using as I was at about 1/2 full and figured I'd have more than enough to get to our destination plus to Gibsons or to another source. I was right but that did not leave much comfort room. Lesson: top up every
chance you get!
We didn't go to Gibsons but made a last minute change of plans to stay longer in Halkett Bay. This was based on the assumption that we'd be able to get gas in Snug Cove (sailing directions said you could get gas there - clearly now we know that that's not the case and hasn't been for a while). Lesson: we should have called ahead and confirmed.
Yesterday we start to head home with one empty tank and the other 1/2 full and start by stopping by Snug Cove and find there isn't gas (this is the first gas stop). I traded a power boater information on where the closest gas dock was for current conditions (low visibility, rain but mostly calm water in the channels). We motor over to Horseshoe Bay where we do find gas (second gas stop). I fill both
tanks (starting to learn from earlier mistakes) and motor the rest of the way home. I was able to complete the the trip from HSB to DC on one tank (good to know for future reference .... though we were traveling with the tide which I'm sure helped a bit).
We probably could have made it from Snug Cove to Mosquito Creek on that 1/2 tank but we would really have been running low and I didn't like the idea of risking the narrows and the harbor with the imminent loss of engine power a real possibility. I felt much better going through the narrows knowing that I had 1 and 1/2 tanks.
