Is there a big difference between aluminum or wood row boats? We've been looking online and in some ways the aluminum is cheaper. What are the pros and cons? Is one more sturdier than the other, or does one hold more weight?

Re: Differences between the tow boats
Aluminum is very light, easy to pick up (with 2 - 3 people), low maintenance. You don't have to do anything to an aluminum boat, except spray it off with some fresh water, when you pull it out of the water. Wood, NO, heavy, lots of maintenance - paint, varnish, chance of leaks. Get the aluminum

Get some bubble bath, mr. bubble, or just dish soap, thinned out with water, spray it all over the boat, you will get it cleaned up and find the leak at the same time. When you see th e stream of bubbles coming out, mark it, get it dried off and patch it up. I think they use a contac cement on the Hypolon boats, or is it neoprene? Do you have a patch kit? Any pieces of material for a patch? The hardware store has pvc rubber used for shower pans, that might stick on there, clean it good with laq thinner, and brush on some glue, both pieces, let dry, then slap them together. You will know if it will work. Or else look up the manufacturers recommendations. he boat supply might have patch kits in stock. Hope this helps.
I have some tips I learned from finding a trailer for my 27 foot cruiser. Really, you can find deals in this economy that make rigging a trailer from scratch too much work.
You need to find the loaded weight of your boat and where the hull needs support from Carver. Your trailer needs to hit the "Chines" correctly, meaning the bunks have to be adjustable to the contours of the hull.
The bunk supports can fit outside, inside, or on top the frame rails Mine started on top of the rails and were converted to the torsion axles, requiring new supports.
The axles need to support enough weight and State laws will say how many axles need brakes. Your choice of electric or hydraulic. The bunks should be made of Cypress, but synthetic decking could be cheaper. Your tires should Load rated D or better and 15 to 16 inch wheels, not 14 inch because of the weight.
There are numerous Boat Salvage yards listed online.
There seems to be a "thing" about the region the boats are used. Some places have orphaned trailers everywhere and others are always married to a trailer.
I have seen Boatyard liquidations with ridiculously cheap trailer prices. Use the internet and look.
Rowing a boat is only an isokinetic exercise if you make it so. The perfect stroke has an acceleration and a deceleration, therefore, it is not isokinetic.
However, resistance does increase with more effort in the middle of the stroke, therefore, this "negative feedback" mechanism has a similar feel as an isokinetic system.
Go to website for the vessel and pull up the owners manual. If none, make sure all water is out of the pontoons (assuming aluminum) Remove and store all cushions canvas soft coverings and electronics indoors. Outboard remove and store inside. Syphon bottom of fuel tank for any water if present, Remove fuel lines and fuel water seperators. Plug opening.
Get under the dash and look at the back. You will see a big nut on the rotary part where the cable feeds into the steering system. Loosen that nut all the way. With the nut loose you can turn your steering wheel until the cable comes out. Then you can remove the steering wheel and the three bolts holding it on.
The boats (or shells) are basically of two types and reflectthe two forms of rowing---sweep rowing and sculling. In sweep rowing each rower handles a single oar (about 12.5 ft or 3.9 m long) in sculling a rower uses two oars, or sculls, (each about 9.5 ft or 3 m long). The word shell is often used in reference to the boats used because the hull is only about 1/8" to 1/4" thick to make it as light as possible. These shells are also rather long and racing shells are as narrow as possible while recreational ones can be rather wide. Most shells today are made of composite materials such as carbon fiber, fiberglass, or kevlar. A few manufacturers still build wooden boats.
Each rower has his back to the direction the shell is moving and power is generated using a blended sequence of the rower's legs, back and arms. The rower sits on a sliding seat with wheels on a track called the slide.
Each oar is held in a U-shaped swivel (oarlock) mounted on a metal pin at the end of a rigger. The rigger is an assembly of tubes that is tightly bolted to the body of the shell.The exception to this are some european recreational boats called "inriggers" which have the oarlock attach directly on the gunwale. The subtypes of rowing shells are classified according to the number of rowers in the shell.
Sweep Boats (each rower has one oar)
These shells can have a coxswain---a person who steers the shell (using a rudder) and urges the rowers on. I have included in parenthesis the symbol used for each subtype along with some dimensions and weights.
Coxed Pair (2+)
Two sweep rowers with a coxswain.
Coxless Pair (2-)
Two sweep rowers without a coxswain.
Coxed Four (4+)
Four sweep rowers with a coxswain.
Straight (or Coxless) Four (4-)
Four sweep rowers without a coxswain. Steering is usually accomplished via a rudder that is attached to a cable that is connected to one of the rower's foot stretchers (this an adjustable bracket to which the rower's feet are secured). The coxless pair has a similar type of rudder setup.
Eight sweep rowers with a coxswain. Eights are 60+ ft (~18.5 m) long and weigh about 250 pounds (~114 kg).
Sculling Boats (each rower has two oars)
Only in rare cases do these boats have a coxswain. Steering is generally accomplished by applying more power or pressure to the oar(s) on one side of the shell. The hands overlap (usually left over right in the US) during part of the rowing cycle, or are always left in front of right.
One rower or sculler. Singles are about 26 ft (8 m) long and less than a foot (0.3 m) wide. Racing singles can weigh as little as 30 pounds (~13.5 kg). There are heavier (~45 to 50 pounds), shorter and wider versions often referred to as recreational singles.
Two scullers. Most racing doubles can be also used as a pair with a different set of riggers designed for sweep oars. When used as a pair a rudder is usually added. There are also recreational versions of sculling doubles.
Four scullers. Often referred to as a `quad' and usually has a rudder attached to one of the sculler's foot stretchers as in the straight four. Most quads can also be rigged as a straight four using a different set of riggers.
Eight scullers. This is rarely seen, though is used in the UK, at least, in junior competition where sweep rowing is not allowed.
There are basically two weight classes for rowers---heavyweight (HWT) and lightweight (LWT).
For team LWT boats, there is a 72.5 kg (~160 lbs) individual maximum, and the boat must average no more than 70 kg (~155 lbs).
The individual maximum for team LWT boats is 59 kg (~130 lbs), and the boat must average no more than 57 kg (~125 lbs).
In the US, the women have an individual max only; no average. In some regattas in the US (usually head races late in the season) these limits are increased by 5 lbs.
A rowing shell is usually built with a particular weight class of rower in mind. Until just recently the Olympics effectively had only HWT classifications.
