Sea Adex RMP 43: vee-nosed punt made better
  |  First Published: March 2016



Is there anything more synonymous with freshwater and estuary fishing than a vee-nose punt in the classic 4m+ range? Hulls of this size are ideal for a huge array of fit-outs, can be towed behind even the smallest of family cars and they won’t break the bank. In fact, I own one myself, along with half the staff here at Fishing Monthly. We’ve all customised our tinnies different ways, from rigging them up as a dedicated tournament fishing machine or as something to keep the kids away from the Xbox.

Fishing Monthly managed to get out on the water with Brisbane-based plate boat builder Sea Adex to put the new RMP 43 through its paces. As the name suggests, the RMP 43 is a 4.3m hull with a 10° deadrise and available in either tiller or side console configuration.

The Hull

The RMP 43 is a vee-nose punt with a slight deadrise of 10°. Built to handle anything, the hull is 4mm plate alloy from top to bottom. Traditionally, a true vee-nose punt has a sharp bow that flattens out to a flat transom. However, the advantages of having a slight vee to the bottom at the transom is that the hull doesn’t slap on the surface of the water as much, preventing the horrible ‘tinny slap’. Just looking at the running shots taken of the RMP 43, it is evident how much a small tinnie relies on the shape of the transom for ride quality. Add to this the 4mm heavy-duty plate alloy design, and the result is an amazing ride for a hull of this size.

One of the advantages of having a dead flat bottom is stability at rest. Most serious punts these days have a deadrise similar to that of the Sea Adex, but this comes at the cost of stability. What Sea Adex have done is place a very wide 150mm reverse chine down on the waterline.

The term ‘reverse chine’ is used a lot in hull design and for anyone new to boating it can be a little confusing. The chines of a hull simply give the hull its vee-shape, box shape or even rounded shape. A chine is the change in angle to ‘round out’ the hull. This dates back to when wooden planks would be used to shape a hull, and every plank placed to change the angle of the hull would create a chine.

Most manufacturers incorporate a reverse chine that deflects outwards, to allow water to be directed away from the boat for a drier ride. Because the reverse chine on the Sea Adex is huge and located on the waterline, it not only deflects spray but aids in the stability of the hull at rest. When you’re on board the RMP 43, or when you’re moving from one boat to another, it’s apparent that the stability of the Sea Adex is exceptional. Overall, the design of the RPM 43 is excellent, providing a very smooth, dry and quiet ride.

LayOut

The test boat was an open, tiller steer version of the RMP 43 which would be ideal for weekends away with the family or a bit of serious club or sportfishing. The seating was very comfortable, with three different positions as well as a slot for a seat or lean post on the front casting deck.

Underfloor storage was huge with plenty of room for bait, live or kill tanks to be installed. Tournament anglers could easily fit this out with batteries for either a 12V or 24V system. The bow has an anchor well, cleat and rope guide with enough room on the bow for an extra sounder as well.

The transom also has some extra storage along with side pockets and elevated trays to keep the battery and fuel tank off the deck. The test boat had a small Raymarine GPS sounder positioned just under the gunwale. The painted finish and fully carpeted deck gave a RMP 43 a very neat finish.

Performance

The tiller steer version of the RMP 43 was well laid out and simple to operate. The big tiller arm and massive gear control lever of the 60hp Mercury always appears oversize when looking at them, but the functionality is very good. The hull performed as a 4.3m plate boat should, having little trouble with the chop, but needed some restraint over big wakes and swell.

As mentioned, the constant deadrise and big reverse chine were the standout features of the RMP 43, giving it excellent stability at rest and perfect tracking, even through big eddies and over chop.

Being a tiller steer setup, we were unable to get accurate rev ranges on the outboard but the 60 Merc was happy to cruise at around half throttle at 16 knots and flat out she was just shy of 32 knots. The hull was stable at full noise and easy to manoeuvre while puttering around.

Prices for the RMP 43 start from $21,000, and options available include livebait tank, kill tank, electric motor mount, berley bucket, rod holders, side pocket storage, side console, centre console, targa tops, bimini tops and more.
