Up and over door might be an issue when open, but I'm proposing to install two RSJs transversely, so a lift of the boat (less trailer) shouldn't involve a load of any more than 250kg on each hoist/beam.
I have also been planning for years that i would install lighter hoist's in the roof, but i need to fix/ support them in the space between inner an outer roof, and hate the idea
to crawl in 30 cm deep blown stonewool insulation so havent yet got to it
Sounds crazy, but we have water circulated underfloor heating in the garage. The reason is that as having water based floor heating in the house, it was easiest and cheapest to use the same heat exchange also in the garage, thus only option was floor heating.
The setup is litle different, the pipes was secured in the rebars before the concrete was poured, a one layer construction, only one thick & and strong reinforced concrete "slab", having EPS insulation below. Same construction possible to do with electric wire heaters i guess.
Downside over her is that can not shut it of totally during the worst winter time because there is a potential risk that the pipes/tubes might freeze and get damaged, trying to fix them deep in the concrete floor is not an easy or cheap job... using glycol would eliminate any issues but have not bothered to change the fluid, don't even now how to do it as the system is pressurized...
In a milder climate think taking care of insulation and having a few of these HeatandPlumb.com: Myson Finesse Electric Radiators - Free UK Delivery
would do the job, using upon need? As the air changes pretty little in a garage most of the time, energy consumption is not huge.
