I see Chrusty1 has now updated his profile and removed all his details. When I looked yesterday his occupation stated Marina Manager, I do wonder if he is a bit more friendly with his berth holders or is the place empty
Anyway, I am based on the Solent and come across all sorts, but I have to say I find it about the same whether stinkpot or raggie, some friendly some ignore you. I have rescued both types and received thanks and a look of appreciation. All I hope for, if I am in need of help, I just hope a raggie or stinkpot will assist. But to date, when I had engine failure and was drifting, seastart has always been there and are very quick to get things moving again.
With regards to OP, I would expect anyone who needed help to at least raise their hand/wave, however I would still ask if they are okay if I see the engine hatch open.
