Introducing the HT21 - 21 Foot 6.4m Hardtop Cuddy Cabin Aluminum Boat Kit. A versatile Sportfisher and Family Cruiser. The open plan of a Hardtop boat lends itself well to adapting to your needs: You can increase the indoor space with a hard wall or canvas wall to close off the back of the cabin, or add a full-length stand-up camper-back for maximum indoor space on those off-season getaways. Or on sunny days, and fishing trips, run it with the whole deck open! It's rare to find this much cabin space on a 21 foot hull.

Versatile: Plenty of room for fishing with friends and the versatility of a Family Cruiser. It’s a boat that will keep the whole family happy.

The Cuddy Cabin forward sports full sitting headroom, and room for two to sleep so you can extend your outings to overnighters or weekend getaways. It has three spacious under bunk lockers for storage in the Cuddy, and can even hide a discrete head in the forward center locker. Add a propane BBQ and a swim grid shower out back and you have all the amenities.

The HT21 is based on our well proven Walkaround 20 hull (link) that's been in service for several decades. With 1/4" bottom plates and 18 degree deadrise she's built to handle waves, weather, and rocky shores with confidence. This is a tough west-coast boat with attractive modern styling that is just as at home in Europe or “down under”.

Flexible Power Options include either single outboard with a trolling/kicker motor, or twin outboard configurations.

    Hey Rick,

    Just wanted to give you an update on the 21 HT. This kit is the best kit I’ve put together so far, everything is fitting perfectly. By the end of the fourth day we were on step thirteen and I can honestly say it’s squared true from end to end. This was with us still cutting parts on the router while I was fitting them together, if all the parts were in front of me I would’ve been a lot farther ahead. Amazing job Rick.
