Could anyone tell me the purpose and benefits of having the two short fins under the bottom of the hull close to the rudder and propeller

Hi Skipper,
besides probably a bit stabilisation when roling ist mainly to cover the propeller from both sides and when grounding. I serves like an open propeller tunnel. The older boats have real half tunnels to cover the propellers.
For some of the lifeboats it's of course also the sliding help on the slipway.
Best,
Joerg

These two keels were added to try and stop the Waveney's horrendous tendancy to roll as the original Americal design (44ft Coastguard cutter) did not have them. As to them helping with prevention of damage when grounding they are completly useless as the props and A frames are much lower than the lower edge of the keels.
