If you can balance the lift and speed you get an effect that must be something like the old horse boats riding they wave. We managed it a bit on 1" ice and found that once you accelerated onto the ice and got the lift you could throttle back to near tickover and fly along until conditions changed. The best effect at this time was the ice in Grub Street singing for hundreds of yards in front. But, as you say on the thick more exposed bits the poor prop took a real hammering with us even having to back and ram on Sheldon. Luck that was a hire boat and they gave us permission to proceed!

AIUI, damage to steel is unlikely, but there is a risk of excess wear on the drive train if you make a habit of ice breaking, as a result of using the prop as an ice grinder. Came up from Alrewas to Fradley yesterday in quite heavy ice - the first time I've felt Sanity's bow lift as she rode up onto the sheet briefly. Lost some blacking, mainly from the rubbing strake where it cuts the water on the shoulder of the bow, but no damage to the steel. 末 All the best Bruce There are no strangers on the cut, only boaters we've yet to meet.
