Your boat was designed entirely as a performance shallow water boat. That means at all costs, even salon room was compromised to performance. That huge divider running directly down the center line of the boat from the steps to the forward bulkhead, from deck to ceiling, over a foot wide is a serious compromise.

So now you have a shallow water boat. Lets compare the shallow water performance to the IP. A particular IP has a draft of 4 feet. To put your boat in the same shallow water requires you to place your keel only half down. So now you keel is at 4 feet.

Problem is, only half of your keel is in the water. This means, only half of your lee resistance is provided. And of course only half of your keel weight is where is suppose to be. The other half of the weight is inside your salon uselessly creating a heeling moment.

The IP owner would have to remove his keel and place it on his salon floor to get the same effect as your boat in this configuration. So clearly, when we compare the performance of your boat in the same shalllow water you are at a serious disadvantage.

You complained that the IP is hard to tack because of its dual headsail configuration. However, its inner jib is invariably a self tacking jib. In situations where constant tacks are required why use the outer jib? In that case the IP owner has it all over your boat. He just turns his wheel.

My argument with you is not that your boat does not head to wind just fine. But you thoughtfully left out all the other advantages of the IP over your boat.
