For those that are interested, we've begun to create a copy of our manual and have placed it here for your review.

This is a profile picture of WhimSea. She's sitting on the hard at the boat broker in Michigan. Her mast is down (the one you might see is from the boat behind her).

To the right is a picture of our mast. To help give you some perspective, that's a Dodge Durango.


Here she sits in the cradle at the Spirit Lake Marina, Minnesota. As you can guess from the ladder we've been working on her, climbing around and generally sitting on her and marveling at the fact that she belongs to us. We've also been working at renaming her. Here's Troy measuring the size and location of the previous name 'Sails Call' to see where we need to put the new graphics.

Here's the finished product. We named her WhimSea. To the right you'll see the finished product. It wasn't an easy task to complete since the weather was also switching between sunny and chilly, but after much elbow grease and scrubbing along with Troy's work at buffing and waxing, we finally got it done and I think it looks darn good.

She's got a nice size cockpit with a table and two stern rail seats, which you can see in the side view of the cockpit to the right. Troy and I spent some time sitting in those seats and watching a beaver run through the harbor our first weekend and can vouch for the fact that they are quite comfortable, as is the rest of the cockpit. Eventually, we hope to get some cushions to make the cockpit even more comfortable. But that's some time down the road.

The interior has ample room for Troy and I and plenty of guests, the galley (to the left) allows for making plenty of food, she sleeps seven in her two staterooms and she has two heads! And the best part for anyone who has spent some time and experienced the inconsistency of the weather on Lake Superior... A Force 10 heater (you can see it, in the picture to the right on the far wall)! This is one of the first pieces of equipment we've tried out and can tell you it works well.

Her navigation station is equipped with all the electronics we need. She's got a nifty little tuck under stool that swings out when you need it to make logging our trips comfortable.
