Interesting. I know the area fairly well and I thought it would be down to N or NE giving a hideous sea state and no shelter. However SSW will bend and scream up the E side of IOM. It is common to have a belt of wind/sea stretching 5 miles out with really grim conditions while beyond that the Irish sea proper is lovely. It may be that they thought they would find shelter by hugging the IOM, but actually found it much worse and so assumed it was worse still further out.
Peel or Douglas would have been good shelter but tough to get into. If they didn't have them already worked-up as ports of refuge and were cold, tired and sick, I can see a call for help looking attractive!
the 1200z 48hr forecast on the 26th gave cyclonic conditions north of IoM - wind all over the place but no more than 15kn. the actual on the 28th was 30kn with gusts to F8. the passage from the Mull to Holyhead is 100m. some of the posts here verge on the sanctimonious with much tut tutting ... there could be more to this which might deserve more than the usual armchair bluster ...
We were on passage from the Clyde to Bangor (NI) overnight 28/29th. The wind was cyclonic and dropped to zero around midnight then picked up to F3 till about 08:00 then we had a NW F6 till arrival in Bangor at 13:00.
Sea state ranged from slight to moderate throughout passage.
Unless your boat has some form of heating I usually find it is just too cold to be enjoyable to be onboard overnight much after mid December! Also as I have a fiberglass hull I like to lift out to delay the chances of osmosis setting in.
If you want a winter pontoon you could try the HM at Brightlingsea - you would need a dinghy to get out to boat and there is no electricity on pontoon. Otherwise could go to Bradwell Marina I expect for a somewhat greater cost!
Thanks Flipper.
Dont worry no chance that I will be sleeping on her over Winter...I hope!! may try Brightlingsea, happy with Mersea for now, I have a dingy with a nice new Honda 2.3.
