I'm sailing around the world with my father!  I have many reasons to choose my dad.  1) The two of us built a sailboat when I was about 10.  We sold it and bought a better one.... He taught me how to sail..or tried to.  I'm not very good.  That's why I need him. 2) He is 83 and I'm not sure how much time we have to spend together in the far future.  3) My mother does all the communicating since he is pretty hard of hearing.    4) The most important:  I love him...he's my pal! 

I thik it would be cool to go sailing. I never had before, but I would go a lone. It sound that you and your dad are really close. I guess sailing would make you two even closer
