YepLakemasters and the channel markers were both wrong?
It was the green buoy just to the right coming out of Friendship. I was pretty dialed in on Lakemaster and I was probably 20-30 yards to the right of the buoy. I also saw a video of two boat that ended up getting grounded at the same spot last week.Not to make you wallow in the mud but can you give more details about the location of that whale for everyone's benefit? And what did you see? Is it on the same side as Friendship and just downstream? By how much downstream?

Sorry that happened, glad no one got hurt. Unfortunately there will be more this year. I don’t trust the ATONS whatsoever, but GPS...usually. sounds like events conspired against you, with the exception of being on the last day lol. Good luck on the repairs, thanks for posting. Words to remember this year.Ok...here goes! I use Lakemaster on my Ranger and in all my 40 years of boating at Lake Powell, I’ve never dinged my boat on a submerged rock, let alone ding my prop. Well, that all changed April 30 just south of Friendship. The sunlight that evening prevented be from being able to see due to the reflection, so I trusted Lakemaster and the channel markers...Big Mistake! Bam!!! Ruined my prop and lower unit. Limped back to the houseboat at the back of Last Chance and towed it back from there. The good news is it happened at the very last day of fishing and we were heading back for the night. The not so good news is the repair bill!
Once you drop off the mesa the ground slopes down gently towards the old channel on the south side. (Hijack warning!) Anybody know where the marine charts get their data on underwater terrain? Soundings? USGS map data from pre-lake times? I'm not sure that I would trust the 1953 data for close elevation accuracy.Image dated today, but probably yesterday. Several surprises along the north (west) side of the channel.

That's the spot. Definitely not a good location for a channel bouy. The rocks are above the water now.Ok...here goes!

Been there and done that coasting over the rock piles all puckered up!Guilty! Here's my track from April 29th. Heading east early morning feeling confident about my bearing until my graph said 20', throttled back quickly and coasted over a rock pile at 5'. View attachment 12933
