Go for it... this is a great opportunity to make a good impression as her cuckold.
Mr. Hers,
Good to hear you're planning to accompany your wife to the BBQ her lover is throwing this weekend. It would definitely be bad form if you were to decline to go, and stay home pouting (which is what it would look like).

My wife showed me a swimsuit she's going to take. I asked her why, if this is a BBQ with people from work. "For the boat. He (her lover) has a boat and is going to take people on it throughout the day." I asked: "Who's going to be doing the BBQ then?" "Oh, he has some local caterers coming to do all of that. It should be fun, he said he'll even show you how to drive [his boat]."
That's very generous of your wife's lover. If his boat includes a cabin or half-cabin, perhaps he'll take you and your wife (only) out with him for a "short cruise," then — when you get the hang of handling it — invite your wife below into the cabin, so she can fuck him while you're driving.
You might consider suggesting this possibility to your wife. (On the other hand, perhaps there will be no need to suggest it.) The daring nature of her doing her lover on-board, with you driving and unable to leave the helm because you have to pay attention, would greatly increase the erotic intensity of BBQ for both of them... and for you as well, no doubt.

I honestly was going to just say hello, make some small talk and spend the rest of the day mingling with everyone else. I thought showing up and meeting him was a big enough step but having extended time together? The thought of going out on his boat where I'm ****** to interact with him let alone being taught how to drive a boat is freaking me out.
Hey, don't worry about it. Treat it as an opportunity to increase your knowledge of small-boat handling. Be curious, and ask your wife's lover lots of questions about every aspect of handling his boat. He'll be impressed by your interest, since that's obviously something he likes to do.
mr.Her's said:
I'm hoping he's very cool. I'm hoping that everything else aside, this is a person I would really want to hang out with. I'm sure he is from what my wife tells me. Everyone seems to really like him.
If your wife wants you to meet her lover, you can be confident he is someone you should meet. If she has informed her lover she wants him to meet her cuckold (you), you can be sure he will be gracious and put you at ease when you're introduced. Let your wife guide you; be attentive and follow her cues re. what she wants you to do and how she wants you to behave; be friendly toward all (especially her lover); and the BBQ — including accepting her lover's generous offer to show you how to drive his boat — will go well for you. Your wife wants to be proud of you for making a good impression as her cuckold; if you do, your status (and your wife's status) will rise in the eyes of her lover and her colleagues, and you will find it a rewarding experience.
If your wife does not take advantage of this apparent upcoming opportunity to fuck her lover while you're driving his boat for them (due, perhaps, to insufficient privacy), you might keep in mind that you should learn as much as possible about driving and handling it because they may have this in mind for the future.
Have a good weekend! When the BBQ is over, don't be too eager to leave... watch your wife, and she will cue you when she's ready to depart. Then, be sure to look her lover in the eye and give him a firm handshake, as you tell him it was a pleasure to have met him and thank him heartily for inviting you to such a great party.
Good luck!
Custer
