After you have done what has been suggested, you have taken all 'reasonable' precautions to minimize the chances of serious damage from a strike IMHO.
I don't think it is possible to reduce these chances to zero, no matter what precautions you take--a strike contains so much energy/second that it could destroy any bonding before it is over or overwhelm it and thus jump to any nearby object, metal or plastic, grounded or not. A tree in my back yard took a direct strike awhile back and did not explode or burn--it just died and had to be taken down. However, EVERY motor in my nearby house was destroyed by the EMP produced by the strike-washing machine, dryer, garage door opener, etc. Seamanship to avoid t-storms, luck and insurance are your last and maybe the only resorts you have when out in such weather.
