What do all of these manufactures have in common? They all make a boat with a 24 degree deadrise angle just like the GoDu 10.5!

But what is Deadrise? 

Deadrise angle is the number of degrees of rise from a level point on the bottom of the keel to the relative angle of the hull, measured at the boat's transom. 

Comparing deadrise angles is a common measure of how soft a boat will ride and more deadrise generally equals the ability to run at faster speeds before pounding becomes excessive. 
For example, let's say two boats of the same size with different deadrise angles are headed across a choppy bay and both captains have the same tolerance for comfort: the boats are called Deep-V and Shallow-V respectively. 

The Deep-V boat can travel faster on average than the Shallow-V and will arrive sooner. It also means, due to its higher average speed, that the Deep-V is traveling higher out of the water while pounding less and as a result is likely to experience less spray than Shallow-V. So because of its Deep-V its a faster and dryer boat for the captain and crew. 

A deadrise of 24 degrees like the GoDu has is often referred to as an “Offshore Deep-V”. These types of boats have been in continuous production by various manufactures since the offshore race boats of the 1960’s and are a coveted favorite of offshore fisherman, both commercial and recreational from all over the world.

Now if you are thinking: “But my dinghy isn't a race boat”, consider this: When a boat is on a plane (cruising on top of the water) it only has about the rear ⅓ of the hull in contact with the water, so for a 10.5 foot dinghy that's only 3 feet of hull in the water! 

The GoDu 10.5 has a cruising speed of about 15-18kn with two people and gear in the boat and a solo captain can travel at speeds in excess of 22 knots!! This is the same speed achieved by boats 2 or 3 times its size, with 3 or 4 times the engine power- but the GoDu is doing it on only about 3 feet of hull! So if you think your planing dinghy isn't a race boat: think again, because these little boats are very fast for their size! 

But why do I need it? 

When you are out cruising for the season, it's natural that you tend to move the mothership whenever the weather is good for sailing and hang out at anchor when the weather isn't so good for sailing. As a result, the wind is usually pretty strong when you're at anchor and that's precisely when you want to get off the boat and explore the most. 

Whether that's going to town, getting out diving or snorkeling at the reef or just cruising around in the dinghy exploring the area. 

The ability to travel in comfort and safely in the dinghy is paramount to your success and happiness while cruising. 

With the wind up, the water is choppy with wind driven waves, a higher deadrise allows you to travel faster and dryer than a smaller one. It also has an awesome feeling of “grip” on the water and will inspire confidence for you and your crew. 

A day spent freediving or snorkeling out on the reef is such a great experience! Dont let it be a pounding slog at half plane all the way out and back. Get a GoDu, so you can GoDu YOUR ADVENTURE. 

Notable Quotes: 

• “We found that 24.5 degrees is the perfect compromise of speed, efficiency and a soft ride. A deeper V would yield a softer ride but at a loss of efficiency,” says Contender engineer Chris Becker.

• “More deadrise typically equates to a better ride in bigger sea conditions” says Todd Albrecht, Jupiter‘s vice president of sales.

• “A 24-degree transom deadrise best suits the boats that Regulator currently makes,” says Lou Codega, naval architect and designer for the brand. “Historically, that has proved itself to produce a hull that creates the best combination of ride quality, stability on the troll, speed, and fuel economy for planing boats.”
