I think the only keel type to be a potential problem would be a wing keel, but even then it seems unlikely. I have a blob rather than a bulb and it has never concerned me.
When our marina needs dredging my keel sinks 2 ft in the mud. My Hanse 311 has a sort. Of bulb but the top part is not flat or wide as one might imagine with a true bulb. I use an erodible anti foul on the keel & find it soon sheds any mud that might form. The keel probably makes a hole & only light silt drops on top. The tide through the mooring must move this anyway. I put 3 cts erodable anti foul on the bottom 2 ft of keel. I do some times push through the mud in the approach creek if arriving a bit early so that must not help either.

I find mud really useful. It's a great natural braking system when a strong wind is blowing me off my pontoon. Not available +/- 4 hours but I can time my entry accordingly. Plough to work myself near as necessary.

To fellow forum contributors, I give thanks for your advice. The comments were contradictory but none the less helpful. I have now put a deposit down on a 1989 Moody 31 MK 2 fin keeler. No blob keel with only 1.52m draft and a good engine to cope with a receding time in prevailing westerly winds

Good luck, with what will hopefully be your new aquisition
