This is how I was introduced to world of inflatable boats. I was hesitant at first but ultimately after being realistic about what we would be doing in the craft, lake exploring / lazy river floating and fishing for $100 what did I have to lose.
Step 1: Getting to Know the Seahawk 4
On the water with 2 adults and 1 child the raft was quite stable but as would be expected it doesn't track or paddle like a hard body boat. But this raft can float in less than 1ft of water and is quite manuverable.
After the fun filled maiden voyage I had three things to improve on: The oars that come with the boat are bit short and I plan to replace these. I have an idea to use the rafts motor mount lugs to attach a skag to help with tracking. The final area and first project was installing a wooden floor for better stability.
Even though the floor mod is a popular one for this raft I had a hard time finding any good construction info or details.
Step 2: Inflate, Measure, Cut
I used 3/8 plywood sheet this was ok but I feel 1/2 would have been a better choice after testing on the water.
Step 3: Sand Edges and Trim
I've seen staples used for this but pointy objects and inflatable things don't get along. Plus after use the foam will pull through the staples and have to be reattached.
Be sure to do a test fit with the edge covering before carpet covering. Also be sure to add a hole in the rear to access the floor chamber filling valve.
Step 4: Cover With Outdoor or Auto Grade Carpet
The basic idea is to lap the bottom side of the carpet over the edges and staple on the top side of the panel then the top cover is cut to the edges and stapled over the overlap. This will ensure all staples are on the top surface. If they start to back out you can see this right away in stead of being hidden underneath. I kept all staples as close to the board edge as possible so that the once the pipe edging was attached it too would cover / protect the boat from loose staples.
Step 5: Test Fit and Finish Up
Step 6: Final Notes
One could go all out adding seats and decks but then you would be in hard side boat money or you could buy a professional grade pack raft that will be rated for extreme rapids and made of ballistic material.
