I am talking to the dealer tomorrow, after having had an hysterically funny conversation with him by email, with me trying to convince him I wasn't a scammer—because I was emailing from the UK, and not able to phone him because I do not have a local SIM. My partner and I are teaching workshops here. She does have a local SIM in her phone, so the dealer and I will chat tomorrow.
This boat is just bare bones, really, but to me good-looking bones: no autopilot, a single instrument (I am guessing that Lowrance is a sounder, but I could be wrong). It looks like a very good hull (it's only 15 years old, young for a wooden trawler).
