wondering about stability

hello i am 12 and my dad and i are converting a 14 foot lowe sea nymph deep v boat. out of coincidence i have the exact same tin as backpains. we plan to do the same conversion as his. the only thing my dad is worried about is the stability of the boat after decking it. we plan to have a kid and 2 full grown men on the boat.if you look at his conversion through the moderators link his username is backpain. any response is very appreciated.

The stability should be just fine. As long as you don't deck higher than the benches, you shouldn't have any problems.

This is the boat you are referring to correct? - https://www.tinboats.net/forum/viewtopic.php?f=21&t=1319&start=50
