I used my 23 Allmand in the bayous and gulf coast for 13 yrs...ran it aground in the mud more times than I care to admit. Many times we had to go overboard and push it out of the muck, sinking knee deep. Even with 3 guys pushing/pulling it was difficult due to the hydraulic suction.
I would always run it shallow in less than 2ft of water to get to the sand beaches at the barrier islands, especially after I went to an outboard on a bracket. What's the worse that could happen? We don't have rocks down here (just oysters and other shells to chew up props and keels) and the tidal range isn't too great.
The 23 Allmand was heavy and your 25 will be heavier, so you'll probably want to avoid doing what we did in the shallow bayous.
I did learn a valuable lesson I'll pass on: If the birds are standing in the water, it's too shallow to plane through!
