Blackness Point Marine is an option, so is Dartside Quay at Galmpton (latter easier to get to) plus campsite & good pub just up the road. Rob/ Steve in the office are very helpful.
If repairs take long, an option if you're down for a few days would be to launch at Blackness, Galmpton or Brixham, them pop the boat on a marina pontoon for a few days - c. £2.50/m /day.
Dartside is accessibble upto 2.5-3hrs of HW.
I'm sure there's be lots of pressure to get this slip fully operational again - they are meant to be widening it to 8m!
