The Stadamsterdam full rigged clipper ship (which is considerably bigger than Astrid) has a 750KW engine (about 1000HP). This is enough to propel the ship at 11 knots. I would also expect that ship to be able to make headway under engine power alone directly into a force 6 wind.
Therefore I think a Severn class lifeboat should be more than enough to tow Astrid in against the force 5 conditions which were present at the time.
The Arun class has about 900HP. I would have thought that would be sufficient as well.
You can't equate the engine powers because the lifeboat's propeller has a pitch and diameter suited to its normal operations.
The other issue is that it would be very dangerous to the lifeboat to have a very large and heavy ship attached on a tow in a big sea. The ship, with far greater weight is going to pull the lifeboat around like a toy.
I'm sure everyone involved did their best to avoid losing the ship while firstly focussing on the priority of saving lives. When you think about it, the lifeboat wouldn't have been able to go around picking up survivors while undertaking a tow.
