Tome is only really looking at ironing his best dresses and a few smalls. (the camouflaged thongs will be OK straight from the wash basket) I think a travel iron maybe 12 volt may do the trick. With gas curling tongs, a 12 volt drier and a battery driven bikini line shaver all will be OK. (perhaps a heart shape trim for valentines?)
While Tome is away practicing fraternising with the Liveaboards on their forum trying to get the answer he wants to hear, I can safely but shamefacedly admit to us having a 110/240v travel iron on board :-( which the invertor will drive.
Will hurredly claim though, to improve my own self esteem, that it has never been used in anger outside of the marina, mostly with real electricity, and only when living aboard while working (whoops, digging a hole for myself again mentioning working).
How about getting an anchor with a smooth, possibly rounded surface (a Spade might be quite good in this respect). Stick it in the engine bay, ideally on top of the block, and motor for a few miles. By this time, it should be nice and hot (be careful lifting it out of the engine bay!) and ready to use. Spread out the item to be ironed on a flat surface (chart table? Tara Palmer-Tomkinson's chest?) and dash away. If the anchor gets too cold to work properly, just motor another few miles and warm it up again.
Sorted!
PS Don't use the anchor for its intended purpose until it has cooled down again; particularly in colder waters, as sudden cooling may lead to distortion of the shank. Though not with a Spade. Obviously.....
I am a weekend Solent Sailor so ironing is what the missus does at home while I'm drinking beer and watching the footie/rugby/cricket or mending the motorbike on non-sailing weekends. I am safe in saying this 'cos she never visits this forum.
I hope.
I pray.
Many, many moons ago I remember my Mother's elder sister had a paraffin powered one. Had a little tank on the back which held about a mug full, and then you pumped it up like an old fashoned blowlamp.
Crushed velvet loon pants and a cheesecloth shirt was always my favourite workaround for this problem but perhaps it wouldn't work as well for Tome today as it did in the sixties!
